Really great #SRA2026 roundtable session this morning by @mitchprinstein.bsky.social , @evatelzer.bsky.social , Brinleigh Murphy-Reuter and Sunny Liu all about advancing responsible social media research. Heartening to hear so many thoughtful perspectives, and no moral panic about teens and screens!

There is no evidence that social media harms children’s mental health Far from ‘drowning in evidence’, real researchers – not pop psychologists – are scouring a great desert looking for puddles

In my essay today for @spectator I argue that #socialmedia bans such as in place in Australia, and being considered in the UK are doomed to fail. The evidence just isn't there that they would help.

I listened to this episode this morning and Julia, I must thank you for your sane and incisive approach to this, at work and at home. I am a developmental psych researcher and it is infuriantingly bonkers how discussed.
Issues mostly generated by naive assertions of causation in child development.

Yes, they were soooo close with 100 days and DSEM and then just neglected the one direction/path that would have given them an iota of leverage in interpretation. Could never get published if only WB-->SM path analyzed.
And then the follow-up schlock balloons to sure, it ain't an RCT.

Agreed, Andrea. That direction is never considered by the pre-convinced crowd.

aaannnndd....PANAS is not a wellbeing measure. Feeling negative emotions is NORMAL.

Please please please MAKE THE SCHLOCK STOP!

Agreed, though I am finding it easier to get the warning across to students with these egregious examples. Somewhat deflates the "he's just an out of touch old man against anything new" tune out.

I JUST posted about another one. A meta-analysis. Zero reality.

On the plus side, great teaching tools.

As an expert, it really was not difficult to catch the bs. But students I gave it to all took it as real.
I am using this paper in all my classes as a cautionary tale.
The good news is, it makes another argument for critical thinking skill development.

Yup. You guessed it. NONE of the 45 references are real!

In journal, Scientia Psychiatrica, is out of Indoinesia, other papers seem legit. Editor did not respond to my email inquiry.

This is the AI age we live in.

all studies were from the past 5 yrs w/ very large samples N>800). I know this literature, recognized none.

I did not notice 1-45 superscript in table title indicating that the 45 studies were referenced numerically.

and citations in text were just those 45

ok, let's look at the references.

I had not really looked at the paper, was just helping undergrad. Table 1 seemed weird

The email (gmail) to the first author immediately bounced back. No such address.

Weird.

Ok, so I looked up the author at her institution in Ghana.

No such institution exists anywhere in the country.

Thus began a modern adventure in scientific research...

So...my undergrad thesis student is doing a quality analysis of studies found in meta-analyses. She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers.

Here's what happened:

Not surprisingly I have lots of thoughts on this. But in a nutshell, Yes, we should support teachers and no students should not be on their phones in class (unless they are integrated into the class plan or supporting learning), but, most teachers and schools had already solved this problem...

the danger is that adults claim victory and believe they have saved the children, when in reality they have just kicked down an already open door and did nothing to support youth mental health (oh, and by the way, we are in the midst of an adult mental health crisis but keep pointing only at youth)

New figures quantify teenagers’ self harm. Once again, we’re hearing social media is to blame. See if you can spot another reason why teens might be more depressed.
