- People are like sushi! Similar in some regards, different in others.
- Common group analyses are based on group averages that discount individual variability & have reduced predictive power
- Even within groups of people with shared characteristics, no 2 individuals are alike
Our new #scicomm poster tries to explain one of neuroscience big challenge of using group averages in easy/fun terms. Inputs/Feedback appreciated! #openscience #openscicomm #opencartoons
