Grumpy IO psychologist with an interest in research methods, meta-science and personality. Views are my own and not those of my employer.

Or maybe that only worked if you were an Ivy League professor. https://doi.org/10.1016/j.obhdp.2011.03.00423 Oct 2026 01:44 +0000at://did:plc:vbodcooc4ubiiusytzzd6dn7/app.bsky.feed.post/3myj2jichms2lhttps://bsky.app/profile/marcuscrede.bsky.social/post/3mxsglegz5k2wA million times this. So unbelievably obnoxious to expect 50 faculty members to give up their time just because you could not come up with a more interesting assignment.

Or was there? Gemini tells me that no rain at all has fallen in Ames over the last 24 hours. Great that AI can get basic stuff like this wrong. I should definitely trust it with important stuff.😒09 Oct 2026 12:51 +0000at://did:plc:vbodcooc4ubiiusytzzd6dn7/app.bsky.feed.post/3mxgzbbznnc27https://bsky.app/profile/marcuscrede.bsky.social/post/3mxfw4uy3vc2tMy 9-year old kid just got a pretty personalized recruitment letter from a university. 😕09 Oct 2026 02:22 +0000at://did:plc:vbodcooc4ubiiusytzzd6dn7/app.bsky.feed.post/3mxfw4uy3vc2thttps://bsky.app/profile/marcuscrede.bsky.social/post/3mx7wromdjc22How mean would it be to point out to someone that a huge chunk of their (very well known) life's work is a function of a well-known statistical artifact?

It strikes me as horrific fraud on other researchers, the public, the employer, and funding agencies - as well as doing great damage to the public's trust in science. How Ariely still has a job is completely beyond me.
