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."
