The observational data: the Survey of Professional Forecasters lets us test some other predictions from the theory. As predicted, “excess” MSE above what variance alone would imply equals twice the disagreement in individual forecasts. (Honestly we were shocked at how well the data fits the theory!)

Here is a graphical version of the key result. Participants are unresponsive to changes in across-model uncertainty (left & middle panels), but reasonably responsive to within-model uncertainty (right panel).

The experiment: participants predict future “sales” data generated by a linear trend plus noise, and report their uncertainty. Sometimes they see the trendline (so only within-model uncertainty matters). Sometimes they don’t (introducing across-model uncertainty).

Very happy to share this paper: Like it says on the tin, we study how simplifying assumptions drive overprecision (excessive certainty) and disagreement (divergence in beliefs), using theory, an experiment, and observational data.

At least in terms of making good predictions there is a clear answer and it is not the one most give to Scott’s survey

I think if your entire organization is resisting your leadership you are not doing a great job of leading? www.politico.com/news/2025/04...

Very plausible but I’m not sure I’d 100% trust this guy

Great piece, which highlights why I think excessive pessimism about the state of our democracy can be counterproductive

Important point. E.g., according to a recent paper by @dbroockman.bsky.social and @jkalla.bsky.social only 20% of the population watches even 15 mins of Fox/month. Only ~5% watches 16hr/mo. onlinelibrary.wiley.com/doi/10.1111/...

Don’t envy the job of university presidents but this strikes me as the right response

Side effect of the leak is we now know why Andrew Baker disappeared from social media

One point of agreement is universities should also be unafraid to fight back against things like funding cuts and endowment taxes

A decent rule of thumb: if you are more confident in your assessment of what is going on than Adam, you are probably overconfident

I can think of someone who is a leading expert on the intersection of democratic institutions and autocracy, has written about measuring democracy, and is the chair of a related APSA section...

As long as he got a 5/5 on the quiz all should be fine, right?
