New working paper with @robertboehm.bsky.social: it is an early version likely needing significant revision, so feedback is very much appreciated. We review multi-level games: a family of economic games that capture tensions within and between groups simultaneously. (1/5) doi.org/10.31234/osf...

There seems to be a broad perception across psychology and neuroscience that work shouldn't be "too technical" in order to reach the broadest possible audience. While I think we should strive for accessibility, I feel that this attitude can also be self-defeating: why are we dumbing down?

== Effect Size and Confidence Intervals (ESCI) check == Lots improved. Has a revamped website and R package on CRAN. Works like statcheck, also checks effect sizes and calculates confidence intervals. Tricky countless edge cases, but after testing it on 1000s of articles, seems pretty decent.

In poverty, do people take more or less risk? Some theories contend that they avoid risk out of caution. Others that they take risks (e.g. crime) out of desperation. In our new paper in BBS, we show that they are the two sides of the same coin: the desperation threshold. Peer commentary call soon!

New paper led by @makitotakei.bsky.social! We found experimental evidence for one of the key theoretical tenets of audience cost theory - those in the challenged country understand that the challenger’s leader would face a punishment for backing down.
