The fall of "When prophecies fail": Another social psychology classic turns out to be based on fabrications and lies. In 1954, Dorothy Martin predicted an apocalyptic flood and promised her followers rescue by flying saucers. In “When Prophecy Fails “ (1956), the

What if people appreciate having an abundance of content and communication, more than they feel overloaded by it? Anne Schulz et al decided to have a look. Results? "We found that appreciation for abundance was about twice as common as overload". Paper: https://t.co/ChAJF02gAh

Another important behavioral (vs survey) social media consumption research (from @RoeeLevyZ, @PriceTheorist & co-authors). 45% of voters only see 5 election-related exposures per day (consumption is driven by heavy consumers). Steady until EDay w/ small peaks around events

“Democracy,” said H.L. Mencken, “is the theory that the common people know what they want, and deserve to get it good and hard.” I apply this idea to the democratising character of social media and connect it to the rise of right-wing populism: https://t.co/fdl1Bf27qD

PARUTION | "Histoire naturelle de la fiction" d'Edgar Dubourg @EdgarDubourg est #enlibrairie. L'auteur interroge ce paradoxe troublant : pourquoi tant d’êtres humains se passionnent pour des personnages et des mondes qui n’ont jamais existé ?

This is good news for debriefings in misinformation research: Debriefings that include fact-checks of the false claims used in the experiment reduce false beliefs, improve attitudes towards the study, and show no signs of negative effects. Feedback much welcomed :)

How effective are user corrections on social media, and does adding a link to a fact check improve effectiveness? In piece led by @Sacha_Altay , we find corrections have small effects, adding a fact-check is unlikely to make corrections more effective https://t.co/hGdsh1oGC8 1/6

In addition to the original UK results, we have now 👏replicated👏 this (TWICE) in the US. The main findings hold strong: information diets are a lot more diverse in attention than in engagement.

Finally got round to reading this paper in detail. It’s a tour de force. If you’re interested in the potential impact of AI on election outcomes you should put it by your bedside. Key takeaway: let’s remain alive to, but healthily skeptical of, the possibility of large impacts.

How harmful is GenAI around elections? Will it trigger a misinformation apocalypse and upend elections? I am happy to finally be able to share @Sacha_Altay’s & my answers to these and other questions on which we have been working for a year and which is out via @knightcolumbia.
