Unpaywalled: Jonathan Haidt vs. social media
Hello everyone! We weren’t able to record a podcast this week, because 1) Stuart was busy and 2) it’s Tom’s birthday. So by way of apology we’re re-releasing this one about some drama last year between Jon Haidt, sworn enemy of smartphones, and some guys who like meta-analyses. Hope you enjoy it!A while back, The Studies Show covered the question of whether smartphones and social media cause mental health problems. Amazingly, that podcast didn’t settle the issue, and the debate has continued—and continued rather acrimoniously.Psychologists—most notably Jonathan Haidt—are currently laying into each other, analysing, re-analysing, and meta-analysing datasets to try and work out whether “it’s the phones”. In this paid-only episode of The Studies Show, Tom and Stuart explain the story so far, and in the process get very disappointed by their heroes.If you want to hear the whole episode and read the show notes, it’s easy to become a paid subscriber at thestudiesshowpod.com.Show notes* The summary of Jonathan Haidt’s upcoming book, Life After Babel* The Google Doc on social media effects maintained by Haidt, Twenge, and Rausch* Christopher Ferguson’s meta-analysis of causal social media effects studies* Very useful online calculator to interpret effect sizes* Study on the (non-)relation between reported and measured phone use* Haidt & Rausch’s first article criticising the Ferguson meta-analysis and re-calculating the effects* Anne Scheel’s critical tweet* Matt Jané’s first article responding to Haidt & Rausch* Haidt & Rausch respond to Jané (and criticise Ferguson again)* Jané responds to Haidt & Rausch, again* Haidt & Rausch’s second (or is it third?) article criticising the Ferguson meta-analysis (this is the one where they note the more basic errors)* Article by Mike Males making the point that, whoever is right, the effects are all very smallCredits* The Studies Show is produced by Julian Mayers at Yada Yada Productions.

Episode 91: Entangled Life and the wood wide web
Everyone has read Entangled Life, the wonderfully-written book about fungi that took the world by storm about 5 years ago. Among many other things, it popularised the “wood wide web”—the idea that trees can communicate with one another through networks of fungi at their roots.But is the wood wide web real? It turns out scientists have some major questions. We air them on this episode.And just to be completely clear, there are no personal vendettas here! Everyone recording this podcast is 100% free of “beefs” of all kinds. Even the co-host who was beaten in a book contest by the aforementioned mushroom book.The Science Fictions podcast is brought to you by Works in Progress magazine. Their most recent article is about the wonderful invention (and history) of the dishwasher, one of several incredible labour-saving devices that have made so many lives just a bit less dull.

Episode 90: Cognitive dissonance
It has happened again. A new paper, based on a tranche of unsealed historical documents, casts serious doubt on a piece of social psychology research from the mid-20th Century. Shocker!This time it’s about some of the fundamental inspirations for the idea of cognitive dissonance—the idea that holding contradictory views in one’s head creates discomfort and a need to change one of the beliefs. So what does the new historical research say? What about all the studies that claim to find evidence for cognitive dissonance—surely the whole thing isn’t a load of nonsense? Listen to this episode to find out.The Science Fictions podcast is brought to you by Works in Progress magazine. They’ve recently been publishing a whole host of podcasts, including the one we mentioned this week, on “the economics of the baby bust” (that’s the opposite of a baby boom, by the way). You can find it and many other podcasts at podcast.worksinprogress.co.

Paid-only episode 24: Creatine
This is a free preview of a paid episode. To hear more, visit sciencefictionspod.substack.comCreatine is the supplement of the moment, but both of us had vaguely heard that this one might actually not be total garbage.On the other hand: there are a lot of surprising claims made about it! If proponents are to be believed, it doesn’t just boost muscle mass – it reduces depression, prevents cancer, and improves your cognitive function.How much of this should we believe, and how much is it just a big load of crap? We thought we would take a look.
