The BBQ was a great opportunity to reconnect with familiar faces, meet new people, and welcome the new cohort of students. For our first-year students, it was a chance to get to know the second-year students and alumni, share experiences, and ask questions about life in the programme.

With good food and lovely weather, it was a wonderful evening spent together before everyone got back into the rhythm of the academic year. A big thank you to our academic director Yvonne Brehmer and Rianne Hurkmans for organizing another great BBQ!

Not All Stress Is the Same
Why stressful moments linked to important goals may feel different
Feeling that your life has direction and that what you do matters (i.e., having a sense of purpose) has been shown to help people stay healthier, remain active, and cope better with stressful life events. However, a sense of purpose is not something that remains constant at all times; it can shift in response to the experiences we have each day. Most of us might know the feeling of ending a day full of stressful encounters and wondering where our sense of purpose went. In this study, we were interested in understanding the immediate effects that stressful events may have on our sense of purpose. To do so, we used data from the Daily Experiences and Health Study collected in British Columbia, Canada, who followed 236 adults for 14 days and asked them, four times a day, whether something stressful had happened and how purposeful they felt. At first glance, the effect of the stressor seemed straightforward: when people experienced a stressor, they reported slightly lower momentary purpose. But that overall link disappeared once we accounted for negative emotions such as feeling sad, anxious, or angry, that stressors also tend to evoke. In other words, part of the negative momentary association between stressful events and sense of purpose seemed to reflect the negative mood that the stressor introduced.
The more interesting story appeared when we looked at what the stressor meant for the person’s goals. Stressors that offered little or no opportunity to pursue an important goal were still linked to lower momentary purpose, even after accounting for these co-occurring negative emotions. These are the kinds of hassles that feel like interruptions: the problems that get in the way without helping you move forward. By contrast, stressors that were connected to goal pursuit were linked to slightly higher momentary purpose after accounting for co-occurring negative emotions. These stressors likely reflect situations where people actively make progress towards their goal, such as giving an important presentation at work or having a difficult conversation with someone. Further, people even felt slightly more purposeful a couple hours at the next assessment points when reporting such a stressor. These findings raise the possibility that goal-related stressors may carry a delayed benefit: although they are demanding in the moment, successfully working through these challenges may leave people with a stronger sense of purpose afterward.
One practical takeaway is to ask a different question when dealing with an everyday stressor: is this stress pulling me away from what matters to me, or is it part of something I care about? That distinction may shape whether a stressful event drains your sense of purpose or reinforces it.
If this topic piqued your interest, you may read the full paper here, or the abstract below.
Objective. This study examined whether everyday stressor occurrence is associated with lower sense of purpose, and whether this association depends on stressor-related goal opportunities, the Big Five personality traits, or trait purpose.
Methods. Data came from the Daily Experiences and Health Study (N = 236, ages 25–87). Participants reported on stressor occurrence and their feelings of purposefulness 4× per day in a 14-day ecological momentary assessment study. Multilevel analyses examined the within-person link between stressor occurrence and sense of purpose, including the Big Five and trait purpose as moderators.
Conclusion. Sense of purpose tends to be sensitive to the occurrence of stressful events, but the relationship may depend on whether the stressor is appraised as an opportunity to pursue important goals.

]]>The post End of Year Conference 2026 appeared first on Character Studies.
]]>The First Year Paper course consists of writing a research paper in the area of individual differences and assessment, under the supervision of an IDA staff member and using an existing dataset of one of their research projects. The students learn to identify a research question, review literature, analyze data, and write a concise and coherent paper. The First Year Paper course is concluded by the End of Year Conference, during which the students give a short presentation of their paper to second-year students, IDA alumni & staff, and future first-year students.
A week ago, on the 26th of May, the 2025-2027 cohort held their End of Year Conference, in which each student presented their First Year Paper. The conference consisted of two sets of presentations, with a “meet & greet” break in between. Future and current students, as well as IDA alumni, teachers, and staff, attended the conference, providing everyone with an opportunity to see what our first-year students have worked towards this year.

Each having a different supervisor and project, the students presented about a broad range of topics, including academic burnout and narcissism, sex and hormonal differences in fear conditioning, subjective well-being and major life events, as well as identity and trauma, and academic self-efficacy and talent use to name a few.


We would like to thank all the supervisors, our academic director Yvonne, and our course coordinator Meeke for making this event so memorable, and supporting the students in their research!
The day ended with some “drinks & bites”, to celebrate each successful presentation, and the end of the academic year approaching soon!

When did you do the IDA master?
2022-2024
How was the IDA Master helpful for what you are doing right now?
When starting my PhD, I really realized how much I have learned during the IDA Master. The IDA Master provided us with the right hard skills (e.g., how to write a research proposal, how to analyse complex data, how to review and write an article). Further, we learned many soft skills (how to work collaboratively together, how to deal with feedback, how to communicate problems within your research team etc.).
What was your favorite course? And why?
I really liked the traineeships as they gave a very realistic insight of what research looks like in practice. Further, I could deepen my interests there.
What was your favorite moment of the time as an IDA student?
My international traineeship was one of my highlights (see below for more information :)) and I enjoyed the graduation very much where you could see that all the hard work payed off, and everybody was happy with what they have achieved!
What was your motivation to finish your studies?
I started this Master to find my specific interest in Psychology. In the meantime I realized that I was really interested in everything related to Educational Psychology. Being able to further dive into this topic through the traineeships, the master thesis and some courses I was very motivated to continue my studies.
Did you experience stress or pressure in your studies, and if yes how did you deal with it?
I did experience some stress. The best for me was to share these with other IDA students, and make the best from stressful periods, like playing tennis after a learning session, or cooking together afterwards. Further, living in a house with 10 girls helped me a lot. They always supported me in more stressful times, cooked for me, and cheered me up.
What can you advise current or future IDA students?
Make the most of all the possibilities the IDA Master is providing. There are essential learning opportunities for later.
How was your overall experience in the master?
Very good!
What did you do in your international traineeship and how did you like it?
We were allowed to choose an Elective Master outside of Tilburg University. Therefore, I went to Amsterdam to follow the Research Master Course on Philosophy of Education which I really enjoyed. Within that course I have written a paper on sex education. I applied with the paper for a Conference on Philosophy of Education in Oxford. I got accepted and I presented a poster there. The four days in this castle with all those interesting people, philosophizing all day long about different aspects of education, made me appreciate research very much.
Are you still in touch with other alumni students?
Yes, I am with some of them. Always great to catch up and see how the life of PhD students at other universities is.
How did you experience the relationship with your teachers?
I think this can best be described with the word colleagues. We learned a lot from our teachers, who created a genuinely collegial atmosphere. This led to a sense of teamwork and made the learning process feel more natural and implicit.
Did you know from the beginning what you want to do after your master? How did you find out what you would like to do?
I did not know from the beginning what I wanted to do after the master. I was mainly interested in Psychology. However, the master showed me that I really liked the diverse work of a researcher. Therefore, within the second year I thought that a PhD might be a good idea which it was.

When did you do the IDA master?
2023-2025
How was the IDA Master helpful for what you are doing right now?
Somewhat. I’m working in People Operations (HR), which is more related to my previous masters in Work, Organisation and Health Psychology.
What was your favorite course? And why?
I really enjoyed the first few courses in the first year where we could explore various psychological differences, such as in personality, intelligence, etc. – they really made me think and I really valued the insights I got from the papers and discussions we had in class. I also really liked the traineeships and my thesis since we could choose to dive deep into a topic of our choice.
What was your favorite moment of the time as an IDA student?
This is difficult to think of a favourite moment, but I really liked the time spent discussing the class contents with the other students – it was very satisfying sometimes since we could match in our level of excitement and interest about various topics and have a foundational knowledge about the topic. Also taking my own time to dive deeper into a topic or get into a flow whilst reading and annotating a scientific paper on something I was fascinated by was super nice too.
What was your motivation to finish your studies?
I think my genuine curiosity about the topics and my determination to finish within the two years.
Did you experience stress or pressure in your studies, and if yes how did you deal with it?
Accepting that it was a part of it, having a good plan and being intentional with my time. Also just relating about it with my classmates was also helpful, knowing we were all experiencing it in our own way.
What can you advise current or future IDA students?
I’d say try to get really into knowing how you learn and work best, and what motivates you to keep going (e.g., working with others, alone, writing things out, searching for more papers because you’re so curious, etc.). And take this time to dive into what interests you most in psychology. It’s a difficult study but if you’re committed and find something in each course that interests you (even just a little bit) it’ll feel worth it.
How was your overall experience in the master?
Really good. I enjoyed the courses, I had a good cohort and I had time to explore so many topics in psychology.
What did you do in your international traineeship and how did you like it?
I supervised a study at the University of Chichester about leadership impression management and how this influences well-being and behavioural outcomes of employees at work. It was quite interesting since we could make use of an Experience Sampling Methods (ESM) design, plus I could visit the university, attend a short conference and learn about the other research being done there.
Are you still in touch with other alumni students?
A few, yes.
How did you experience the relationship with your teachers?
The teachers were very open and helpful. It was really nice to have a more close relationship with them than I experienced in my bachelor studies, especially during the traineeships since I did require some more guidance and support in these courses.
Did you know from the beginning what you want to do after your master? How did you find out what you would like to do?
I already did a masters beforehand, in Work, Organisation and Health Psychology in Nijmegen. Thus, I planned to perhaps combine my studies in some way, now I started off in HR and I’ll see where that leads me. I considered the option to go into research or do a PhD but I never felt a strong pull in that direction.

When did you do the IDA master?
2023-2025
How was the IDA Master helpful for what you are doing right now?
IDA contributed not only to the development of my theoretical and methodological skills (e.g., mixed-method study designs), but also to strengthening my professional attitude and networking abilities throughout the master’s program. I now apply these skills in my role as a junior researcher.
What was your favorite course? And why?
My favorite courses of the program were the internal traineeships. The traineeships helped me grow as a researcher by learning from experts and expanding my knowledge on different methodologies and skills. They also gave me the opportunity to apply these in practice, tailored to my interests.
What was your favorite moment of the time as an IDA student?
I don’t have one specific favorite moment, but the time spent in between classes stands out the most. Spending time over coffee or lunch with fellow IDA students, or collaborating on assignments together, truly made my studies special.
What was your motivation to finish your studies?
Before starting the master’s program, I was unsure whether a career in academia suited me or if I would enjoy working as a forensic psychologist more. For this reason, I chose to combine both tracks. However, during IDA I discovered that research was in fact my preference, which motivated me to complete the master’s and confirmed my ambition to pursue a career in academia.
Did you experience stress or pressure in your studies, and if yes how did you deal with it?
Yes, I experienced a lot of stress and self-proclaimed pressure. Everyone in the program is very smart and ambitious, which can sometimes feel overwhelming. However, if you focus on doing your best, you will realize that you are capable of more than you initially thought. It also helped me to talk about this with fellow students, as everyone is going through the same thing.
What can you advise current or future IDA students?
Don’t forget to pause ever now and then to reflect on how far you’ve come and all that you’ve accomplished. And most importantly, enjoy the journey. Before you know it, you’ll be at the IDA graduation and you will probably miss this time more than you expect.
How was your overall experience in the master?
Although the program could be quite challenging at times, I wouldn’t have wanted to miss it for the world. I learned so much in a safe and supportive environment, surrounded by people who truly helped me grow.
What did you do in your international traineeship and how did you like it?
For the international traineeship, I attended the Division of Health Psychology Annual Conference in Cardiff together with other IDA students. Although it was not my first conference, attending one abroad was a particularly valuable learning experience. I gained insights into how to effectively set up a research presentation and further developed my networking skills. Additionally, I really enjoyed exploring the city in our free time.
Are you still in touch with other alumni students?
I am still in touch with several alumni students from my cohort. Although it can be difficult to find time to meet, as we saw each other so frequently during IDA, we still make sure to see each other regularly. I formed friendships for life during the master’s program.
How did you experience the relationship with your teachers?
The close relationship with teachers is one of the aspects that makes this program so special. Because of the small cohort, there is a lot of room to interact with teachers. They go above and beyond to support the students and are open to collaborating on fun and meaningful traineeship projects.
Did you know from the beginning what you want to do after your master? How did you find out what you would like to do?
At the start of the program, I was unsure whether I wanted to pursue a career in academia or as a psychologist. Throughout the program, I discovered that I am most drawn to academia and to conducting research focused in forensic psychology, particularly focused on crime prevention and interventions. This combination feels like the perfect fit, which I now get to apply in my role as a junior researcher.

]]>The post What comes after IDA? appeared first on Character Studies.
]]>Most of our alumni choose to pursue a PhD: among those who graduated in or before 2024, 70% are currently PhD candidates or have completed a PhD.
About half of these positions are at Tilburg University, while others are spread across the Netherlands, Europe, and beyond.

However, not everyone follows the same path: some pursue a PhD, others don’t! While many alumni stay in academia and pursue (postdoctoral) research, teaching, or policy advisor roles, others move into the private sector, working as data analysts, HR development specialists, or research analysts. Some ever work for the Dutch Military or Government, and of course, a number pursue clinical careers.

A truly exceptional path taken by an alumni, is that of a 2019 graduate who was selected as a Topklas (Top-class) candidate, a highly selective and prestigious track. She is currently following a 6-year combined training as a GZ (healthcare) and a clinical psychologist, alongside a PhD track at GGZ Oost-Brabant, uniquely bridging clinical practice and scientific research. This trajectory reflects the interdisciplinary nature of the IDA program, and the range of opportunities available after IDA.

]]>The post Understanding those with BPD: how early relationships shape emotion regulation appeared first on Character Studies.
]]>In the course “Dynamics of Individual Differences“, students write a blog post on a topic of their interest that is related to an aspect that differs between individuals and changes across the lifespan. Mila Le Truong shared her blog post with us, enjoy the read!
Have you ever watched a person you love experience mood swings, feel like their emotions were out of control, or been terrified that their loved ones would abandon them? For many people, those emotions fade as quickly as they arise. For others, however, such feelings are constant and overwhelming, and for those supporting them, these situations can be confusing, painful, or frightening. This can be the reality of those living with, or supporting someone with, borderline personality disorder.

Borderline personality disorder (BPD) is a mental health condition marked by emotional instability, unstable sense of self, and chronic feelings of emptiness (Mayo Foundation for Medical Education and Research, 2024). The daily lives of people with BPD are like rollercoasters: unstable, with intense (emotional) highs and lows, that impact many aspects of their lives and decrease their overall happiness (Wibbelink et al., 2025).
The emotional challenges faced by people with BPD don’t appear out of nowhere but are often connected to how their brain and emotions learned to function when they were infants (Crowell et al., 2009). Understanding the connection between early life experiences and later emotion regulation is essential if we want to offer better support to people with BPD. So how exactly do early caregiving experiences shape the emotion regulation patterns of people with BPD, and what does this mean for those supporting them?
Emotion regulation, or ER, is our ability to understand, manage, and respond to our emotions in a way that is healthy and appropriate to the situation (Center For Mental Health, 2025). These skills begin to develop in infancy, as babies rely on interactions with their caregivers to regulate their feelings (Calkins, 1994): when a baby is upset, the caring touch or soothing voice of their parent teaches them to manage their emotions. In this first period of life, our brains are still developing, and regulation relies on external sources. These repeated moments of comfort teach a baby that emotions can be soothed and understood, helping them develop their emotion regulation skills (Calkins, 1994). Over time, these experiences become the infant’s foundation for emotion regulation and will become especially important when the growing child starts self-regulating.
In general, the family context is a crucial external source of emotion regulation. Children may learn about ER by observing those around them, and therefore often learn from how their parents react to and express emotions. Additionally, the emotional climate of the family: what parenting style is used, how emotions are dealt with (whether they are talked about, or rather swept under the rug and ignored), if the parents have a good and emotionally healthy relationship (Morris et al., 2007). Children also often face better outcomes if their caregivers respond to their distress in a consistent, warm and predictable way (Benoit, 2004).
For someone supporting a person with BPD, it is important to understand that a child who did not grow up with consistent safety, comfort or emotional stability, may grow up without a strong ability to regulate their emotions, because their environment did not teach them how to do that early in life. This means that when people with BPD have intense reactions that we may interpret as “overreactions”, these are their normal reactions, they reflect an inability to self-regulate and use skills to manage their emotions.
So, what happens when a child’s emotional needs are not met early in life? While positive early caregiving can foster ER, disruptions such as invalidation, trauma, or chronic stress can negatively impact this process.

Some children grow up in invalidating environments: households in which their emotions are often dismissed, minimized or invalidated. In such situations, they do not have the opportunity to learn how to communicate their emotional needs (Linehan, 1993, as cited in Grove & Crowell, 2017). Additionally, invalidating caregivers may reinforce extreme expressions of emotion, reacting only when the child’s emotions are very intensely or overwhelmingly expressed (Linehan, 1993, as cited in Grove & Crowell, 2017). Not only do these negative interactions increase in frequency and intensity over time, but they also teach the child that their feelings don’t matter, or aren’t worth understanding, unless they show very strong displays of emotions. This prevents the child from learning to understand their feelings, instead leaving them confused about their emotions or making them think that their emotions are not valid. Other forms of early adversity, such as trauma and chronic stress, can also impair emotional development.
In stressful situations, the quality of the relationship between infant and caregiver is important. If the caregiver reacts in comforting and predictable ways, this can protect them from stress. However, if the caregiver is causing the environment to be invalidating or traumatizing, the child’s early emotional experiences will be characterized by confusion, fear, or isolation, which will impair their ability to recover from negative emotional events, and limit the development of their ER skills (Mosquera et al., 2014). These early experiences can help explain the intense emotional reactions you may witness today as someone supporting a person with BPD. Lacking a reliable internal system to manage strong feelings can lead to, as an adult, experiencing rapid mood swings, fear of abandonment, or overall strong emotional reactions.
If early environment is so important, you might wonder: why doesn’t every child in an invalidating home develop BPD later in life?
Describing the emotion dysregulation that may result from a child’s environment alone does not paint the full picture. BPD is best understood as resulting from the mix of their personal natural sensitivity, which they are born with, and the environment they grew up in (Crowell, Beauchaine, & Linehan, 2009).
Some people are simply born more emotionally sensitive than others. In fact, many people who develop BPD were more emotionally sensitive as children. They may have felt more intense emotions, have had more strong reactions, have struggled more with calming down, or been more impulsive in reacting to their feelings. In research, this emotional sensitivity is often described as higher trait anxiety, higher trait impulsivity, and the temperament traits of negative affect and low effortful control (Grove & Crowell, 2017). Imagine a child who feels everything more strongly and is more prone to negative emotions: this must already be quite hard for them. While this sensitivity may be manageable, or become a strength, if paired with a supportive environment, it can be a major vulnerability when faced with an invalidating environment. Indeed, when this sensitive child must face an unsafe, dismissing or humiliating environment, they won’t learn to calm themselves down, when necessary, and instead feel like their emotions are confusing, or wrong.
Emotional struggles caused by biological sensitivities and an invalidating environment often become more apparent during adolescence. For many teenagers, this period of their life is characterized by increased emotional reactivity and vulnerability to poor outcomes (Hare et al., 2008). For adolescents who had early emotional difficulties, however, puberty can intensify early vulnerabilities. On top of the typical teenage risk-taking or mood swings, they may also experience changes that include more intense and prevalent emotional struggles. Importantly, these patterns of emotional dysregulation in those with early vulnerabilities often do not dissipate, as they usually do after adolescence. Instead, they may persist into adulthood, turning into the chronic emotional instability that characterizes BPD (Kaess & Cavelti, 2025).
Understanding how these patterns develop is important not only for clinical treatment, but also for the people who live alongside, and care for, individuals with BPD. For example, emotional outbursts often do not aim to seek attention, control or manipulate, especially when they happen between a person with BPD and someone they have a close relationship with. These outbursts are rather the portrayal of long overlooked sensitivity; they show an attempt to survive what feels like an overwhelming threat. While this does not excuse harmful behavior, it may help understand where it is coming from.
People with BPD may have strong emotional reactions, which cannot necessarily be rationalized with. What you can do in this situation, however, is to stay calm, and be consistent in your reactions. Stability is often something that people with BPD struggle with and therefore need others to remain calm and collected. Reassurance can be helpful in the moment, but its effect is often temporary, because the underlying fear and trauma have much deeper roots. Additionally, people with BPD may struggle to feel where their person ends and where others begin, which can make them very sensitive to the emotions of people around them (De Meulemeester et al., 2021), so your emotion regulation impacts them, and staying stable and emotionally regulated will help them more than reacting strongly or becoming upset. Lastly, while it is important to empathize with people with BPD, especially if you are supporting them in your daily life, it is also crucial to keep boundaries and to reinforce them. These things do not replace professional treatment but rather show that a supportive environment can make a powerful difference.

So, what if you, or someone close to you, developed BPD? How do you help yourself or another beyond a supportive environment?
BPD can be seen as the result of a mix of attachment experiences, invalidating environments, and a biological vulnerability. The good news is that the patterns shaped in early life, that may have led to BPD, can change. And vice versa, the emotion regulation skills that a person with BPD may never have had the chance to learn in childhood, can still be learned as an adult!
Several evidence-based approaches can support the healing process of people with BPD. Psychoeducation helps people understand their emotions, and gain self-awareness of these emotions (Lam et al., 2020). Cognitive reappraisal teaches ways to reinterpret a situation, so its emotional impact changes (Buhle et al., 2014). Dialectical Behavior Therapy (DBT) combines acceptance of feelings and reality, with a challenge to change yourself in beneficial ways, by teaching crucial skills for people with BPD, such as tolerating distress, and regulating emotions (Cleveland Clinic, 2022). For supporters of people with BPD, one of the most powerful things you can do is to be a consistent, calm and validating presence in their life. Professional treatment is crucial but having a support system that understands the roots of these struggles and responds with both compassion and boundaries, helps make the journey more bearable.
Understanding what BPD is and where it comes from doesn’t just reduce stigma, it helps us respond with empathy. For those with BPD, healing is absolutely possible, and no one has to walk this path alone.

Imagine, you are on a first date with a guy. You both went to a restaurant, had a nice meal together, chatted for a bit. At the end of the date, however, you realized it wasn’t a match for you. So, after thanking him for the night out, you politely told him you don’t think there was a connection. All of a sudden, the nice guy you were having dinner with earlier turned aggressive, insisted you give him another chance, an explanation, and eventually insulted you for rejecting him: “You weren’t even pretty anyway”, “You’re a stuck-up person who’s never going to find a man like this”.
Does this sound familiar? Maybe it’s something you or a friend has experienced. Maybe you are the person on the other side, dissatisfied with how your date turned out after spending such a nice time together and thinking things were going to go somewhere. The disgruntled individual above is a common example of an “incel”—a type of man that has gained popularity recently for their controversial ideals and behaviors.

An incel, short for involuntary celibate, is a person, most often a man, who feels entitled to sexual attention from women and are disgruntled that they are not getting it. They believe the reason for their struggles is that they were placed at the bottom of the social hierarchy due to lookism—discrimination based on physical appearance. They believe women are behind this unfair placement and are the source of all their problems. Thus, incels hold a lot of anger and resentment towards women. In the date scenario above, for example, we can see showcased the entitlement (demanding for another chance), aggressiveness (insulting), and lookism ideals (“You weren’t even pretty anyway”) of an incel. Figure 1 and Figure 2 further illustrates incels’ entitlement towards female attention and their hostility when denied it. Notably, incels also often have a big online community that shares their frustration and grievances, and reinforces their ideologies.

Why does this matter? In recent years, there has been a growing number of cases of violence against, but not limited to, women carried out in the name of incel ideologies. Most famously, the shooting of Elliot Rodger killed six and injured 14 people in the United States (ABC News, 2014; see more: BBC, 2018; Rodger, 2014; Rosdahl, 2014), but violent attacks and homicidal cases also arose in Turkey, Canada, and Italy (Icinsel, 2024; Cecco, 2023; L’Unione Sarda, 2022; see more: Kelly et al., 2021). However, to say all incels are violent is wrong. Reports show that only a small percent of incels is prone to physical violence (Costello & Buss, 2023; Hoffman et al., 2020; Moskalenko, González, et al., 2022). In the context of everyday life, however, incels do pose a large threat of harassment, assault, stalking, and generally creating an unsafe environment for women. What is more, incels know their beliefs are looked down upon by society, so they try to hide it, making them more dangerous. These two factors combined create a pervasive problem that is hard to ignore, no matter what gender you identify with. Therefore, I want to discuss with you what factors might predict a person being an incel. As a woman, this might help you be more aware about the problem to avoid danger for yourself. As a man, it might be helpful to know if you yourself are described by incel behaviors, or if any of your friends might be.
All men are not created equal, and neither are incels. There are some personality traits commonly seen in incels, including shyness, having negative body images, a lack of social skills, loneliness, and suicidal ideation (Stijelja & Mishara, 2022; Zhang et al., 2014). In terms of psychological states, inceldom is often linked to depression, anxiety, paranoid thinking, and insecure attachment—they struggle with trust, intimacy, and emotional expression in their personal relationships (Ciocca et al., 2022; Fontanesi et al., 2024; Moskalenko, Kates, et al., 2022). There is also a lot of resentment present in an incel. They feel bitter in their lack of a romantic relationship and believe that the bad things happening to them are outside of their control, that they can’t do anything about it (Fontanesi et al., 2024).

Maybe you did not expect this, but even the location of where you live can also predict if you might be an incel or not. A study by Brooks and colleagues (2022) looked at Tweets with incel content, and found that such Tweets often arise in areas that have high mating competition for men. This means in places where there are more men than women, fewer single women, higher income inequality, and a smaller gender gap in income, it is more likely that there are men who share incel ideologies.
Not just characteristics of the person themselves, many incels share common experiences in their lives that predispose them to being an incel. Many incels reported a history of childhood abuse or bullying (Anastasio, 2024; Moskalenko, Kates, et al., 2022). What is more, a lot of incels felt they were sexually and romantically inexperienced, that they were sexually “off-time” compared to their peers (Stijelja & Mishara, 2022). Especially in their adolescent years, incels often felt they were not living up to the masculinity norms of “being muscular”, “being hot”, and “getting a lot of girls” (Scaptura & Boyle, 2020; Utterback, 2024).
This gap between societal norm and real life is reminiscent of one’s failing to follow what psychologists call the master narrative (McLean & Syed, 2016). A master narrative is what society thinks one’s life should be like, what events should there be, and when should they happen. A personal narrative, in contrast, is what a person thinks their own life story is, why they think certain events happened, and how they personally relate to it. A person engages in meaning-making to make sense of events in their life and how they relate to their identity, to then incorporate into their personal narrative (McAdams & McLean, 2013). For an incel, they may feel that they failed to follow the master narrative—“getting girls”, so they try to cope with this gap through destructive meaning-making—believing they can’t “get girls” because “girls are inherently shallow and only like good-looking guys”. Consequently, they emerge with a new personal narrative, a narrative of an incel—“I don’t like girls, because although they should be giving me attention, they are not, because they only care about looks and muscles.”

Lastly, it is rarely the case that one becomes an incel in isolation. Incels often have a community of like-minded individuals who come together to share their grievances (Byerly, 2020; Mansour & Kidd, 2024). Such communities affirm and reinforce men’s negative sexual experiences with acknowledgement and approval, creating an echo-chamber of incel ideologies (Costello & Buss, 2023). Another element that makes incel communities such a black hole of misogyny is the “Us vs. Them” narrative that they promote, with “us” being the ostracized but enlightened group of incels who have realized the “true malicious nature of women”, while “them” are the fooled but privileged others who are being rewarded by the dating market (Wilén, 2024).
But it is not just the community that makes an incel, incels also choose themselves into their communities. The corresponsive principle in psychology describes how the person and the environment factors interact in shaping one’s personality: we choose or are chosen to be in the environment most fitting to our personality, and that environment also reinforces the personality traits that allowed us to join in the first place even more (Roberts & Wood, 2006). To illustrate, in the case of incels, their communities online reinforce their aggression towards women, like we discussed. But research found that men were often already using incel vocabularies and harboring anger and extremist tendencies even before joining incel communities (Lahnala et al., 2025; de Roos et al., 2025). This supports the claim that incels likely selected or were selected into incel communities because such communities suited their personality. Aiolfi and colleagues (2024) explored this interaction more, theorizing that incel communities likely attract people who are already prone to violence, to then give their frustration a form (through gendered violence and harassment) and a narrative (because women’s cruel nature made you sexually undesirable) that justify their aggression towards women. In other words, although a man might not have been spiteful towards women before and was only frustrated with his negative sexual experiences, joining an incel communities can exacerbate his resentful and aggressive tendencies, to eventually make him a hateful and violent incel.

Hopefully through the information I have shared, you now have a deeper insight into what can create an incel. If you are a woman, maybe this can help you foresee who around you might become an incel, to avoid or even intervene and help them if you can. If you are a man who sees yourself in the traits described, don’t worry, it doesn’t mean you are necessarily a violent or bad person. You can consider taking some time to self-reflect and learn to control your emotions, which can help defuse your aggression. It might also be helpful to explore the negative effects of masculinity and lookism ideals, to then deconstruct them and build a healthier worldview (Aiolfi et al., 2024). Working with a professional to develop social skills, a higher self-esteem, and positive sex education can also be beneficial. It is important to keep in mind that, even if you are an incel, not all incels are violent and vengeful people. Often, they just need some help and do not know where to get the support they require.
To sum up, in this blog post we have discussed how the personality traits of a person, their environment, and the events in their life can predispose someone to being an incel. Most critically, it is not just the communities that make an incel, it is also an incel that chooses their communities—there is an interaction between person and environmental factors that makes predicting inceldom complicated and dynamic. It is to be noted, however, that the phenomena of incels is still an emerging field of research, with many questions left unanswered. In future posts, would you want me to dive more into how harmful incels actually are? Do you want to know more about how you can help yourself or a friend who you think might be falling into the incel echo-chamber? Let me know what you think and if you have any suggestions!

]]>In the course “Dynamics of Individual Differences“, students write a blog post on a topic of their interest that is related to an aspect that differs between individuals and changes across the lifespan. Janne van Schijndel shared her blog post with us, enjoy the read!
Does your teenager all of a sudden spend the whole day in their bedroom listening to heavy metal, gangsta rap, goth, or other types of music that parents sometimes find unsettling? Or maybe they are frequently attending concerts with friends, dressing and maybe even behaving differently, and talking about music as if it is their whole life?
Many parents encounter a moment when music starts to play a more prominent role in their child’s life. Research consistently shows that music listening is a substantial part of adolescence (Delsing et al., 2008, Miranda & Claes, 2008, Selfhout et al., 2009). In research on adolescent development, most teenagers report listening to music daily, and across a wide range of genres (Ilić et al., 2024). But there are individual differences. Some adolescents dive deeper and longer into music than others, and some choose to listen to rebellious types of music, where others choose more easy-going genres.
Maybe your child is one of those that listen to music endlessly and in addition chooses the more rebellious genres. Then you may wonder if this musical obsession is changing your child. Does it affect their mood, their behavior, their values, maybe even their personality?
And yes, adolescence is a period of rapid emotional, social and psychological change, so having these concerns is understandable. This blog explores how music – according to research – influences adolescent development, particularly regarding personality, identity and well-being.

First, some reassurance.
Music does not directly change a young person’s personality traits or behavioral inclinations (Corrigall et al., 2013; Delsing et al., 2008; Lesiuk, 2018; Miranda & Claes, 2008). Listening to heavy metal does not make adolescents aggressive, rap does not cause criminal behavior. Goth music does not make teenagers depressed, and classical music does not make someone intelligent or disciplined. Traits like extraversion, conscientiousness and emotional stability develop gradually, influenced by genes, temperament, relationships and a person’s environment. Even very intense music preferences and habits do not directly affect this development.
Similarly, music does not cause or cure depression. However, young people who feel low may choose to listen to certain types of music that reflect or even reinforce these feelings, which is why these kinds of feelings and music often go together.
So, if music does not directly influence your child’s personality and identity, why then, is it such an important topic and pastime for them and what effects does it have on their development?
Research suggests that there are indirect links between music preferences and personality and identity development. These effects on personality and identity arise through friendships, emotion regulation, and identity exploration. Aspects that are known to be extremely important in adolescence, and music can be intertwined with them.
Exploring new friendships is increasingly important during adolescence, as young people try to find others with whom they feel understood and accepted. Research shows that adolescents often prefer social circles with friends that share the same music preferences (Miranda, 2013; Selfhout et al., 2009). This often provides mutual feelings of connection and belonging. A link between music, personality and identity lies within these friendships and can be explained by a psychological theory called Social Identity Theory by Tajfel and Turner (Brown, 2000; Selfhout et al., 2009). According to this concept, people build their social identity partially on the groups they belong to. Subsequently, as they want to be accepted and to feel that they are part of the group, adolescents may adopt the habits and behaviors that are common in the group. So, the changes in behavior and personality in your teenager that may be visible over time arise from the social contexts they select, and any wish or pressure they feel to adapt to fit in. It is not a result of the kinds of music they choose to listen to.

A second important development during the teenage years is that of emotion regulation, and this development can also be guided by music. Adolescents are faced with heightened emotional responses that rapidly arise and may feel hard to manage. Teenagers often use music as a tool to regulate these possibly disturbing feelings (Loureiro et al., 2024; Miranda & Claes, 2008; Miranda, 2013). They may choose to listen to music that calms them down, energizes them, or helps them understand their feelings. This usually is a healthy way for adolescents to learn to regulate their emotions. Sometimes music is even incorporated into therapeutic settings, to help adolescents deal with or to prevent anxiety or depression (Miranda, 2013; Rossi, 2024). Obviously, in emotion regulation, whether it is self-initiated or therapeutic, listening to music is not intended to change personality, but used to support expression of emotions and coping.
During puberty and adolescence, music may also play an important role in your child’s exploration of who they are (Delsing et al., 2008; Miranda, 2013). During this period, adolescents usually see more and more clearly who they really are. In relation to this, the field of personality and identity psychology uses the notion of self-concept clarity, referring to the degree to which someone has a crystallized, consistent and clear picture of who they are (Becht et al., 2017; Van Dijk et al., 2013).
Musical preferences fluctuate through life, and interestingly, during adolescence the fluctuation of these musical preferences may indicate to what extent a teenager’s self-concept clarity has been developed (MacDonald & Saarikallio, 2022). When self-concept is not so clear, adolescents may experiment with different genres and accompanying mood induced by music. As self-concept clarity becomes more crystallized and consistent, music preferences often also become more stabilized.
For most teenagers, music is an important but accompanying feature of their adolescence to help them explore their identity. For a smaller group however, music becomes central to identity development as they may even choose to pursue a music related career. Research on music students shows that those who choose music-related careers are more likely to have personalities characterized by intuition and feeling, traits associated with emotional sensitivity and value-oriented thinking (Lesiuk, 2018). These traits partly characterize these adolescents before they choose their careers, so their choice does not influence their personalities. But once they have chosen their career, music will become an even bigger part of their life and their identity.
Lastly, music also plays a role in how people see their past and imagine their future. People construct a so called narrative identity (McAdams & McLean, 2013), an evolving story that describes where they come from, how they have changed, and where they envision they are going in the future. These life stories are often built around meaningful and self-defining moments, which creates coherence in the life story and in the identity of a person across the lifespan.
For many people, music is closely linked to memories and emotions, and that is why songs often have personal meaning. Specific pieces of music are often associated with important people and moments in our lives, such as friendships, major life events, or specific emotional periods. Music may remind us of certain people and moments, but it can also help structure the narrative identity.
But besides individual narrative identity, music can also influence social narrative identity (Van Poecke, 2017). For example, in Indie-Folk communities, members listen to a specific kind of music in which collective storytelling is embedded. This music describes shared values and life philosophies, and contributes to understanding and coping with oneself and life’s challenges. In this way, listening to Indie-Folk helps to develop personal and shared narratives.

In sum, research paints a clear picture: music does not directly shape personality traits. But it does have an indirect influence through social environments, emotion regulation, and identity exploration, all of which may have a subtle effect on one’s personality traits and identity development.
This can of course still be a cause of concern to some parents. Some music choices and also any new behaviors your child displays can feel unsettling or concerning. In most cases, these preferences simply reflect your child’s exploration of their personality and identity. A way of finding out who they are, where they belong, and how they can cope.
Sometimes, when your child enters adolescence, it becomes harder to keep the conversation going and to stay connected with them. Key to understanding new behaviors and to staying connected, is open communication with your teenager. These new directions in music could turn out to be a very good starting point to talk with them about their emerging interests. Ask them what their music means to them, how the music makes them feel, and who they listen with. This may give you valuable insights into the new worlds your child is exploring, musically and socially, and into who they are becoming.
