TikTok science is making you overconfident



Easy-to-understand shortform science videos can lead people to overestimate their scientific abilities, according to a new study.

Presenting complex material clearly is a key part of good science communications: a way for the general public, who may lack the high-level knowledge of experts, to understand and engage with important (or even just interesting) scientific information. With TikTok, Instagram Reels, YouTube, and other platforms, scientists and science communicators have ready-made audiences with whom to share their knowledge.

Simplifying scientific material too much in order to fit the short video format, however, may have unintended consequences. That's according to a new study in Frontiers Psychology, led by the University of Cologne's Sara Salzmann. Her team looks at short, entertaining online science videos, finding that the most easily understood video summaries can lead people to feel more confident in their own ability to evaluate the study themselves, even if they had no specialist knowledge.

Participants were 179 university students, mostly in their mid-20s and from non-psychology disciplines, to avoid specialist knowledge of the topics covered in the study. They were randomly assigned to watch one of two types of animated videos based on real psychology studies: either plain language summaries using everyday language, or scientific abstracts using academic terminology. Half of the participants in each group also watched a short educational video beforehand which explained the 'easiness effect', a common bias where people are more likely to trust information that's easier to understand, as well as overestimate their understanding of the study.

Each participant viewed four videos from their assigned condition, then rated how credible they found the research, how confident they felt in judging its accuracy, and how likely they were to seek more information, comment, or share the video online. By comparing responses between the groups, the researchers aimed to understand whether simplified videos disproportionately inflated people's confidence, and whether the de-biasing video would help to reduce that effect by giving participants context for their self-belief.

The results found that the plain language summaries did lead to a better understanding of scientific content, and were also seen as more credible. There was also evidence of the 'easiness effect', with participants also having greater confidence in their ability to evaluate the study themselves after watching these plain language summaries — regardless of whether or not they had been made aware of the bias beforehand.

Interestingly, however, participants were not more likely to make decisions like sharing content based on plain language summaries. This, the team says, suggests a more general caution about actually acting on scientific information without further input: "making decisions involves a certain level of commitment, which participants might have been hesitant to express," they write.

The study had a few limitations, the first of which is that intentions were self-reported and may not actually reflect real world behaviour. The sample was also undiverse, made up of highly educated young people, and other variables were also unaccounted for: political orientation or prior trust in science and social media weren't explored but may have influenced results. Future research could explore these factors.

Overall, however, the study's results do suggest that short, plain language animated videos may be an incredibly useful tool for disseminating scientific content and enhancing the engagement of the general public. We may need to be cautious too, though: while making science easier to understand can boost trust and accessibility, it may also lead people to overestimate their ability to critically evaluate research, potentially fuelling the spread of misinformation. Going forward, researchers may want to explore what shapes how people respond to scientific content — and to ensure that efforts to make science more accessible don't come at the cost of genuine understanding.

Students’ personalities change over the course of semesters


A new study finds students become less conscientious, open, and agreeable as term time wears on.

10 July 2025

By Emily Reynolds



Those that go to university or college often feel like they rapidly grow into new versions of themselves in this new and challenging environment. As such, the extent to which being in a fresh educational landscape causes shifts in our personality, and how, is the subject of some research interest.

Proponents of the Personality Stability Perspective believe that personality doesn't change all that much, with shifts only really perceivable when we observe traits over years. On the flip side, the Situational Perspective posits that there's variation in our personalities day-to-day, and even hour-to-hour, depending on the situational context we find ourselves in. Those who look at personality from a developmental standpoint also point to evidence that personality traits shift as we mature — especially as we adapt to social role changes when we reach adulthood and navigate transitional periods.

Writing in Frontiers in Psychology, Stephanie M. Anglin and colleagues put these perspectives head to head, investigating a particularly relevant period for potential personality change: the first semester of the school year. They discover that student personality does shift as they transition to college life, along with changes in wellbeing, social support, and health behaviours — insights that could prove useful for educators and universities seeking to better support student mental health.

Participants were 282 U.S. college students, recruited during the autumn term of 2023, who completed surveys at two points: early (weeks 2–3) and two-thirds through the semester (weeks 8–9). At each point, they completed the Big Five Inventory (a measure of five core aspects of personality), as well as reported on various aspects of their wellbeing and social life, health behaviours, academic engagement, and extracurricular activities.

In a finding which may not shock many students, participants' wellbeing seemed to decline across the semester, with students reporting feeling less happy and satisfied, and more stressed as time wore on. Their sleep and exercise routines also suffered, though the health of their diets remained the same across both timepoints.

Perhaps surprisingly, though, students didn't report spending any more time studying as the term progressed (though they were more likely to be absent from class). In general, they also spent less time with friends, their social support suffered, and relationship conflict rose. Personality traits were consistently related to these changes: more neurotic students were more stressed and less happy, while the more extraverted and conscientious had better wellbeing and healthier habits.

When comparing data from early and late semester, the team observed some changes in participants' Big Five personality scores. The dimensions of neuroticism and extraversion largely stayed the same, but students showed meaningful decreases in conscientiousness (as the Situational Perspective would predict, with students getting increasingly comfortable with their new situation), openness, and agreeableness. These changes to openness and agreeableness, the authors share, were unpredicted by all three existing theories of short term personality change.

While it's difficult to pinpoint exactly what might lead to such a shift, the authors suggest that it could be down to students starting the term with greater openness to new environments and relationships, and this enthusiasm may gradually taper off over time. Or, they suggest, it could be that the increasing social and academic demands of college life start to undermine these traits.

Interestingly, there was significant variability between participants: though overall trends did point to specific shifts, students differed in the degree to which their personalities actually changed, suggesting that some may be more reactive to situational pressures than others. Future research could explore what individual, social, and structural factors help explain these differences.

Despite being interesting, the findings should be interpreted carefully, the team warns. Participants were asked to reflect on their personality "over the past week", meaning their responses may have been shaped by extremely short-term changes in mood or memory. The study also had some selection bias: students who dropped out after the first survey tended to report much more negative experiences, meaning the final sample may not be fully representative.

Still, the research offers valuable insights into the pressures students face at a key transitional moment: while short-term declines in some traits may reflect temporary disruptions, they don't necessarily signal longer-term problems. Recognising these patterns may help educators, mental health professionals, and institutions better support students through the ebb and flow of academic life.

When you love someone with a mental illness or history of trauma


Daughter/mother, clinical psychologist/advocate-educator team Michelle D Sherman (PhD LP ABPP; pictured, left) and DeAnne M Sherman (right), with a new resource.

11 June 2025


Loving someone with a mental illness or history of trauma can be challenging and demanding. When your loved one is doing well, you may feel calm and hopeful; however, watching them struggle can be immensely painful. You may dedicate a lot of time and energy to supporting your loved one, and it can be easy to neglect your own feelings and needs. Further, many families suffer in silence which can magnify confusion, isolation, and pain.

We, a daughter/mother, clinical psychologist/advocate-educator team in Minnesota (USA), have been creating resources for families for 20 years. Our new release, Loving someone with a mental illness or history of trauma: Skills, hope, and strength for your journey (Johns Hopkins University Press, 2025) aims to educate, comfort, validate, and empower families.

It's a book for family members and friends who care about an adult who has a mental illness or has experienced trauma. We specifically address major depression, bipolar disorder, anxiety, schizophrenia, and posttraumatic stress disorder (PTSD).
Why did we write this book?

We ground this book in both our personal lived experiences and in Michelle's 30+ years of clinical experience working with individuals, couples, and families who live with a variety of mental illnesses.

In my (Michelle)'s work across diverse settings, including as the director of the Family Mental Health Program in a VA Medical Center, I have been repeatedly struck by how many family members/friends feel invisible. They frequently work tirelessly to support their loved one, but their experience and efforts are often ignored.

Inspired by this awareness and desiring to help, in the late 1990s I created family education programs regarding mental illness/PTSD. In facilitating these group sessions, I was in awe of what transpired among these families, including the power of connection, the ability to be understood, and the knowledge that they are not alone. Group participants were often hungry to learn new skills and to both give and receive support from other families.

For a wide variety of reasons, many caregivers never access a support group or therapist. Stigma, schedules, access, insurance coverage, waiting lists, and lack of awareness are but a few of the barriers that keep people from getting support.

I wanted to try to emulate and translate some of the in-person experiences into a book format, hoping to broaden access to the skills, information, and sense of feeling seen. So, I approached my mother (an advocate and educator) and asked her to join me in the writing process… and she said yes! Loving someone with a mental illness or history of trauma is the result of our collaboration and reflects our commitment to seeing and supporting caregivers. We hope readers experience it as a 'support group in a book', as it is filled with not only research-based skills, but passages from families with lived experience who generously allowed us to share their stories in their own words.

Equally importantly in our writing process, we drew upon our own lived experiences as we journey with family members and friends who have a mental illness or have experienced trauma. Our lived experiences inform every angle of our work; they highlight the considerable gap in the available resources, ignite and sustain our passion, motivate us to produce the best possible work, and make our writing especially meaningful.
How is our book different?

Although many valuable books explain various aspects of mental illness, we wrote this book specifically for family members/friends… providing hope and strength for their journey. It's important for caregivers to be seen and to have their experience validated.

We offer opportunities to reflect on thoughts and feelings, including open-ended questions, interactive activities, and checklists. Writing can provide a chance to name, organise, and process experiences. Research has found many benefits of writing about deeply personal emotions and thoughts, such as decreasing blood pressure, strengthening your immune system, decreasing depression and anxiety, and improving sleep and overall well-being. Writing can also provide the opportunity to find deeper meaning in the challenges and perhaps understand the situation from a new perspective.
No easy solutions

We do not strive to provide all the answers; easy solutions simply don't exist for complicated situations. However, we do offer a great deal of information, empowering and practical skills, up-to-date resources, and optional interactive activities to guide you in reflecting on your feelings and experiences. The information and recommendations are grounded in research, in principles of self-compassion, and in the evidence-based therapy models of cognitive-behavioral therapy (CBT) and Acceptance and Commitment Therapy (ACT).

Specifically, readers can:Learn tools to cope with difficult emotions
Reflect on strategies to empower your loved one
Acquire skills for strengthening your relationship with your loved one, including communication and limit-setting skills
Consider how stigma and discrimination around mental illness have affected you and your loved one
Learn strategies to support your children and help them cope effectively
Explore ways of managing common challenges, such as when your loved one declines professional help or misuses alcohol or drugs
Understand how your loved one's traumatic experiences can impact you and your relationship, and how the two of you can work together as a team
Find ways to build your personal resilience and be compassionate with yourself

In summary, we balance straightforward, research-based information and recommendations with an empathic voice to attempt to connect with both minds and hearts. We strive to create a space in which readers can move beyond simply learning facts to courageously and honestly looking at their experience. In addition to presenting strategies grounded in science, we offer recommendations and tools that have helped other families.
What about the kids?

We have also been writing books for 20 years for teens whose parent manages a mental illness or history of trauma. These young people are at increased risk of developing mental health problems themselves, but are sadly often invisible. Our most recent book, I'm not alone: A teen's guide to living with a parent who has a mental illness or history of trauma (2nd edition, 2024), helps to fill the significant gap in resources for these youth. To learn more, see sample pages, and check out other resources we have developed, see our website.

Eight ways to support your kids and help them cope



Figuring out how care for your partner, your kids, and yourself can be a lot to juggle, especially during rocky times. The good news is that kids are pretty resilient! The majority of children raised in families managing a mental illness do well. Research has found that resilient children tend to have strong social support, a sense of purpose, hope and optimism, active coping skills, a sense of belonging, good problem-solving skills, and the ability to regulate their emotions. So, although having a parent with a mental illness can be a bumpy road, most children cope effectively.

However, we know that these youth are at higher risk for developing emotional problems themselves. It's impossible to predict if any particular child will develop a mental illness because so many different factors come into play. Importantly, parents can take specific steps to help their kids, including teaching them how to understand and cope with feelings, recognizing early signs of more serious problems, and seeking treatment early. All of these steps can help children's long-term well-being.

Although an in-depth exploration of how to support children is beyond the scope of this book, we offer eight suggestions to help you as parents and to foster resilience in your kids.Take care of yourself. The single best thing you can do as a parent is to take care of your own well-being. Being good to yourself helps you be present for your kids. You are being a good parent when you are intentional about self-care. Not only are you improving yourself, but you are also being a good role model for your child. So, instead of feeling guilty for doing that yoga class after work, remember that committing this time for yourself is actually good for everyone!
Spend time alone with your child regularly. It can be helpful to schedule one on one time with your child on a regular basis. Your child can look forward to that quality time together. Although you may occasionally have serious conversations, dedicating this time to playing, having fun, and hanging out can strengthen your relationship. Of course, what you do together and the frequency of the shared time depend on their developmental level. (Some teenagers are most ready to talk at midnight!) You know your child and can suggest activities they will enjoy doing with you.
Talk openly about the mental illness and offer information in bite-size chunks, using language your kids can understand. Children are perceptive. Although they may not fully understand what they see and feel, they usually sense when someone is struggling. As children fear what they don't understand and often blame themselves, it's important for them to know what is going on. We believe it's important to be open and honest, using developmentally appropriate language. By naming and openly talking about the situation, you also have the opportunity to discuss how it's impacting them.

Because these conversations can be awkward, you may want to ask for help from a professional, a family member, or a friend. Resources listed at the end of this chapter can help you with these discussions.Listen and encourage your kids to share their feelings and questions. When you name the mental illness as the elephant in the living room, you open the door for children to share their feelings and ask questions. Although you may plan topics to address in specific conversations, your child may also raise the subject at random times, perhaps on the way to school or at bedtime. Be open to ongoing dialogue, and let them know you want to hear what they're thinking and feeling. The questions kids have and their reactions to mental illness change over time, so your explanations need to shift accordingly.

As a parent, you may not know all the answers or what to say, and that's OK! You may consult with a professional or family member to think through how to respond. As children discuss and begin to understand their parent's illness, they may develop greater compassion and empathy for others, and may begin to appreciate that life can be uncertain at times.Offer reassurance. In addition to being honest about the fact that your family is dealing with some challenges, it's important to offer reassurance. Although you decide what is appropriate for your unique situation, some helpful messages include

You're not alone. Over 1 in 20 American adults has a mental illness like your mom or dad. Many families are affected.

You didn't cause your parent's illness, and it's not your fault.

We see you. We realize this situation affects you. We want to support you.Create a support team for your children, possibly including their own therapist. Your partner's mental illness can consume a lot of time and energy, which can result in your having less to give to your kids. Encourage your children to spend time with other kids and to explore their interests outside the home.

You may also be intentional about creating a support team which may include their own individual therapist. Many other people can also help your children, such as family members, friends, faith leaders/elders, and community members such as coaches, teachers, and neighbors. These adults might create a regular ritual with your child (such as shooting hoops or getting ice cream together) or they may make themselves available when times are especially rough.

Are there adults in your kids' lives who are especially supportive? If so, who?

Remember, you don't have to go through hard times alone. Asking for help takes courage. People often want to support you but just don't know how. Be specific about what they can do to be helpful, such as picking up groceries, dropping the kids off at school, or spending time with your loved one so you can have some time alone.Empower your kids and instill hope. It's important to approach conversations in an honest yet positive manner. Instill confidence in your children that they can manage this difficult situation and have coping tools for the tough times. As a parent, you know that sticking to daily schedules and routines can build resilience, but take breaks and be flexible when needed. Help your children focus on what they have control over.

Children can be comforted by optimistic messages such as

We have doctors, counselors, relatives and friends who are helping us during this
difficult time.

Mental illness is treatable. There are many medications and therapies that can help your parent to feel better. Although we don't have a cure right now, scientists and doctors are developing new treatments all the time.

We've been through hard times as a family before—we can handle this!

Although you can't cure your parent, there are ways you can help and support them. Your parent loves it when you_______________________________ (fill in the blank with small things your child can do, such as give hugs, pick up their room, or send a loving text message).

Dating a Trans Person



https://megjohnandjustin.com/gender/dating-trans-person/#more-492

In this week’s podcast we answer the following question:

I’m an older queer guy who’s just started dating a really lovely trans man. Apart from talking to him, which we are doing, where can I get helpful advice and insight into my own “stuff”? I came out late in life – and I am not really used to a lot of the gay scene – which is probably an advantage! Any advice or comments gratefully received 🙂



Here’s a quick summary of some of the ideas we discuss.
Everyone is different

One key idea we talk about here is that often the best advice about how to date, have sex with, or otherwise relate to a trans person (or any other person with specific experiences) is actually what’s best for everyone. For example, it’s always best to assume that the person you’re dating will have a different body to anyone you’ve been with before, which will work in different ways, and that they’ll likely have different sexual desires – if any, and a different relationship to gender. Making those assumptions about anybody is a good starting position. That’s why we don’t give specific advice about trans people, disabled folk, people of certain sexualities, etc. in our book Enjoy Sex.
Transphobic, cisnormative culture

That said, we do live in a wider culture which assumes that certain identities, bodies, experiences, desires, etc. are ‘normal’ and which marginalises, objectifies, and or stigmatises others. That has an impact on everyone. In the case of trans, it’s generally assumed that people will remain in the gender they were assigned at birth (i.e. be cisgender), and trans genders are often seen as somehow debateable in a way that cis genders aren’t. Sadly the rates of hate crimes against trans people, and relatedly mental health problems among trans people remain alarmingly high. For example Stonewall recently found that eight out of ten young trans people had been bullied, one in ten had received death threats and – unsurprisingly given that – almost half had attempted suicide at some point.

That is going to have an impact on people in relationships. It can mean that trans people are particularly likely to have gone through tough stuff in their lives, and all the implications of that. It can mean that cis people have internalised some of the sensationalist and negative messages about trans people. For example it’s worth checking in with yourself about whether you have any assumptions about a trans partner, or whether you’re objectifying them or seeing them mostly through the lens of their transness, rather than as a full human being.
Power imbalances

There are power imbalances in pretty much all relationships which can make it easier or harder for each person to consent to things (e.g. where they want to go on a date, if they want to have sex, etc.) So in a relationship where one person is trans it’s worth having conversations about the potential impact of such dynamics, and how a cisgender partner can make it as easy as possible for them to be open about where they’re at. Of course there will be many other intersections in play in any relationship which are also worth discussing in this way, e.g. differences in age, class background, first language, etc.
Networks and communities

Different groups, networks, and communities will be more or less clued up about gender. If your own family and/or friendship group isn’t very aware it’s worth thinking about how best to navigate that if you’re going to be introducing a trans partner to them. They shouldn’t have to be doing the emotional labour of dealing with transphobic comments, or educating people. Not all trans people are open about being trans – some see it very much as something in their past, for example. So never tell anybody someone’s trans status without being absolutely sure that’s okay with them. If they are open, then it’s worth doing some checking out with any individuals or groups you’re hoping to introduce them to. If those people aren’t safe-enough then they don’t have to meet. If they do want to meet, perhaps they can do a bit of 101 education before they do so. There’s some great introductory stuff online on places like Gendered Intelligence, Everyday Feminism, and Julia Serano’s website.

If you want to engage with queer, gay, or LGBTQIA+ communities, spaces or events then again it’s worth checking out which are fully trans aware and inclusive. Sadly not all are yet. It’s often better to be reassured in advance than going along to something where a performer makes transphobic comments, or another attendee asks inappropriate questions.

The book that Meg-John wrote with Alex Iantaffi is a great starting point for thinking about your own gender, and how you relate to other people’s genders. You can find details – and our podcast about it – here.

How a bio-psycho-social approach supports people with chronic pain




We evaluated an innovative service in South London to assess impact and replicability







The PEACS Project

The PEACS (Pain: Equality of Care and Support in the Community) service was an innovative approach to chronic pain management that adopted the bio-psycho-social model, delivered by King’s Health Partners Mind & Body Programme in collaboration with the StockWellBeing Primary Care Network in Lambeth.
Context and challenges

Chronic pain affects approximately 34% of UK adults and has profound impacts beyond physical discomfort, influencing employment, mental health, and quality of life. The burden falls disproportionately on certain populations, with women, people from lower socioeconomic backgrounds, and Black communities experiencing higher prevalence rates. Traditional medical approaches often fail to address the complex interplay of physical, psychological, and social factors that influence chronic pain.
Goals of our work

The Tavistock Institute conducted an independent evaluation of PEACS between July 2022 and December 2024, seeking to assess:The development and implementation of the service across five GP practices
The impact on participants’ experience and health outcomes
The impact on the wider healthcare system effects, including healthcare utilisation and costs
The feasibility of replicating the intervention across other Primary Care Networks
What we did

We adopted a developmental and theory-driven mixed-methods approach that combined both quantitative and qualitative elements, includingObservations of intervention workshops
Interviews and focus groups with participants, staff and stakeholders
Analysis of participant surveys and health assessments
Review of healthcare utilisation data, including GP appointments and medication use
Cost-utility analysis to assess value for money
What we found

The PEACS service demonstrated notable success in engaging traditionally underserved populations, with the majority of participants across project cycles and levels of engagement being from Black backgrounds and the proportion of Black participants increasing from Year 1 to Year 2.

Key outcomes included:Improved self-management: Participants showed statistically significant reductions in pain catastrophising scores and improvements in physical health measures.
Reduced healthcare utilisation: Long-term follow-up showed 58% of participants reduced GP visits and 48% reduced medication use over 12 months.
Cost-effectiveness: The programme demonstrated good value for money, with cost per Quality Adjusted Life Year falling within NICE’s acceptable range.
Social connection: Over two-thirds of participants reported feeling less isolated as a result of the programme, with community engagement activities seeing sixfold increase in year 2.
The report

Building on the findings of the year one evaluation report, we published the comprehensive evaluation report in March 2025. The evaluation report provides detailed analysis of PEACS’ development, implementation, outcomes, and potential for replication. It offers insights for healthcare professionals, commissioners, and policymakers interested in addressing health inequalities, particularly for those working with chronic pain management in diverse communities.

Key findings suggest the bio-psycho-social approach adopted by PEACS effectively balanced reducing unnecessary healthcare utilisation while improving access for previously underserved groups. The report highlights both the successes and challenges encountered, providing practical recommendations for future implementations.
