🚨 New working paper!
How well do people predict the results of studies?
@sdellavi.bsky.social and I leverage data from the first 100 studies to have been posted on the SSPP, containing 1,482 key questions, on which over 50,000 forecasts were placed. Some surprising results below.... 🧵👇
Very interesting work by @evavivalt.bsky.social and @sdellavi.bsky.social. Particularly intriguing is the finding that a surprising negative relationship between confidence and accuracy is accounted for by a subset of persistently overconfident forecasters.

Dunning-Kruger effect in practice:
In 53k forecasts across 100 projects, people who are more confident are actually much less accurate.

Not quite sure how to put it all in words, but I just spent an extraordinary day celebrating my dissertation adviser, Larry Katz. Feeling grateful, proud, and (re-) inspired.
Larry has raised so many extraordinary economists that being in the same room as them was overwhelming.
Nobel prize winner George Akerlof (my former colleague) on the firing of statistics officials:

I was the AEA's President Elect as the first Trump term began. We worried about government statistics then, and appointed a committee that included members (such as Google's Chief Economist) who might be in a position to help make reliable statistics available if the government went dark.

New short meta-survey on the SSPP: can you predict how well people predict?
Try your hand at it:

I have both *thoughts* and *feelings* about Trump attacking Harvard. And I want to share them with you.

The Social Science Prediction Platform has a new feature: a leaderboard showcasing those who provided the most forecasts or were the most accurate. Forecasters can opt into displaying their name.
You can also see your own rank if logged in. Check it out! @socscipredict.bsky.social
