📣 New research report on sexting in Czechia: over one-third of adults and nearly half of 18–29 y/o exchange sexually explicit messages, photos, or videos. Sexting is a common part of digital relationships, but it also brings risks such as unsolicited content and sexual coercion. 👉

Congratulations! ✨

Should the UK follow Australia’s under-16s social media ban? It could do more harm than good Children may be put off telling adults about something harmful they’re not supposed to have seen.

🖋️"An outright ban on social media platforms for under-16s is problematic. It neglects young people’s rights and voice and penalises them rather than targeting social media platforms.

Professor @jessicaringrose.bsky.social argues Australia’s under-16s social media ban could do more harm than good.

CRISPR as a microbial immune system In 2003, Mojica wrote the first paper suggesting that CRISPR was an innate microbial immune system. The paper was rejected by a series of high-profile journals, including Nature, Proceedings of the National Academy of Sciences, Molecular Microbiology and Nucleic Acids Research, before finally being accepted by Journal of Molecular Evolution in February, 2005.[3][4]

TIL the original paper describing CRISPR, by Francisco Mojica, was rejected by 4 journals and took 2 years to be published

Addiction Fiction: Dopamine Is Not Why Kids Love TikTok Nowadays, it seems we can be addicted to anything – not just alcohol and drugs, but pornography, random Internet browsing, video games, and smartphones. Academic research papers have investigate

Today Ive written about the Dopamine Myth...the belief dopamine makes activities like video games or social media "addictive". All the talk of "dopamine hits" is pseudoscientific nonsense...neither reflecting how brains nor pleasant activities work.

Happy to share my new study, publ. in Social Science Research 🎉 Bottom line: Yes, adolescents use their phones a lot 🤳 But I find no support for the notion that this use displaces reading, homework, hobbies, physical act., sleep... Instead: Changing media preferences 📺 ->📱. doi.org/10.1016/j.ss...

Non-academics: if you see an interesting academic paper on here and you can’t access it due to a paywall just email the author and (depending on the state of their inbox 😜) they will generally be thrilled you are interested in their work and send you a copy.

A screenshot of the paper, titled "Bridging qualitative methods and open research"

My comment about open research and qualitative methods is out! I argue that open research needs to take seriously the notion that "rigour" looks different for different methods and can learn from qualitative traditions. It feels very apt to be at #QMIP2025 for this publication day rdcu.be/evEpk

Our paper (with @davidsmahel.bsky.social and others) on how adolescents feel after sexting has been recently published in New Media and Society! You can read the study here: doi.org/10.1177/1461... (🔑 open access)

Abstract: Building on the idea that subjective evaluations of social media use (SMU) may shape well-being effects, this study investigated how two “social media mindsets”—agency (perceived control over SMU) and valence (perceived effects of SMU)—relate to self-reported and logged SMU, and four well-being indicators (depression, anxiety, stress, and life satisfaction) in a South African sample of young adults (N = 1,858; M age = 21.01). Agency mindsets were negatively correlated with SMU and positively with well-being, while valence mindsets were associated with higher SMU but not with well-being. Logged SMU showed weaker associations with mindsets and well-being than self-reported SMU, suggesting differences between perceived and actual behavior. The findings replicate, extend, and in some cases contradict prior research, emphasizing how users’ sense of control is more important for well-being than SMU duration or perceptions of its effects, and that more work is needed to understand whether the “mindsets” concept is fruitful. Lay summary: This study investigated how young adults’ feelings about social media—whether they feel in control of their use (agency) or view it positively (valence)—relate to their actual use and mental well-being. The study involved 1,858 participants from South Africa using both self-reported and actual logged social media usage data. The results show that people who feel more in control of their social media use tend to use it less and report better mental well-being. In contrast, those who see social media as more positive spend more time on it, but this mindset did not directly relate to well-being. The data collected from logs of actual usage show weaker relations with well-being compared to people’s estimates and to their mindsets. These findings suggest that a person’s sense of control over social media plays a more important role in their mental health than how much time they spend on it.

New in JCMC with @bronwynec.bsky.social: People who feel more in control of their social media use tend to use it less and report better well-being. Seeing social media as positive was associated with more use, but not well-being. 👉 doi.org/10.1093/jcmc...
