Normal Curves: Sexy Science, Serious Statistics

Your Brain on AI: Is ChatGPT making us mentally lazy?


Listen Later

ChatGPT is melting our brainpower, killing creativity, and making us soulless — or so the headlines imply. We dig into the study behind the claims, starting with quirky bar charts and mysterious sample sizes, then winding through hairball-like brain diagrams and tens of thousands of statistical tests. Our statistical sleuthing leaves us with questions, not just about the results, but about whether this was science’s version of a first date that looked better on paper.

Statistical topics

  • ANOVA
  • Bar graphs
  • Data visualization 
  • False Discovery Rate correction
  • Multiple testing
  • Preprints
  • Statistical Sleuthing

Methodological morals

  • "Treat your preprints like your blind dates. Show up showered and with teeth brushed."
  • "Always check your N. Then check it again."
  • "Never make a bar graph that just shows p-values. Ever."
