Introducing bluffbench, a new tool to evaluate how well LLMs actually see data plots.
When we trick LLMs with secret #RStats transformations, they can miss the visual contradiction.

When plotting, LLMs see what they expect to see - Posit
Data science agents need to accurately read plots even when the content contradicts their expectations. Our testing shows today's LLMs still struggle here.

I wanted an #rstats package to exist so I spent $20 and got Claude Code to build it for me.
Plus a shiny app using it: https://jcarroll.shinyapps.io/kanjiexplorer/

Wow. The discussions in the Annals of Statistics were... rough, in the 80s 😅
That being said, interesting paper and discussion. (Thanks to Yannis Yatracos who sent me this reference!)
