Today in @worksinprogress.bsky.social, I reflect on Donald Shoup's legacy. Perhaps the most interesting question: how did the most unlikely professor kick off an international parking reform movement? substack.com/home/post/p-...

I’m looking for responses to replications that attributed failure to stimuli becoming invalid with time (e.g., Shafir and Cheek 2024 JDM on choose/reject effects), or to stimulus selection more generally. Discussions also welcome (e.g., @olegurminsky.bsky.social and Dietvorst 2024 JCR). Pointers?

Previous research shows that people sometimes view moral questions as objectively true, while other times treating them as true only relative to different perspectives. In our new paper, we present evidence that social rewards may explain this apparent inconsistency...

Request: Are there examples of replications or studies examining whether results change when tested with a larger or different sample of stimuli?

There is a famous article titled: "How to show 9 is bigger than 221"... It critiques between-subject comparisons. Not enough people know the result is artifactual. You only get it when using a 1-10 scale (!) So people say "well, 9 is 9 big". Change scale, no effect.

Most papers comparing clustered data methods use biostat/econ language, so I tried to write one using psyc/ed language that covers the origin of the independence assumption, how each method handles ind. violations, and types of questions best-suited for each method psycnet.apa.org/record/2024-...

In the real world, many effects are non-linear. This new paper by @urisohn.bsky.social offers an intuitive explanation of the challenges with standard methods of testing interactions, along with a revised toolbox. In addition to changing a few lines in my R code, this changes how I think about data.

I can never think of a good answer to the “what’s a piece of advice…” question, but I thought of one (& will promptly forget it): when someone gives a valid critique of your work, ask them to join your team, invite them for a talk, buy them a cake, do whatever you can to foster that relationship.
