are better-performing face recognition models more human-like? turns out: NO
in terms of how we see/treat different faces as similar/different to each other, there seems to be tradeoff: better models are LESS human-like
so they already work in some 'alien' ways...

The Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement.
In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99.
At the same time, we show meta-analyses combine these results as if they’re equivalent.

How many versions of the Iowa Gambling Task (IGT) exist? And how much does this affect research using the IGT? More than you might think. 🧵

I reckon they haven’t thought that far ahead.
