How can a brain disease increase creativity? We derive a brain circuit from creative tasks demonstrating they share reduced activity in the right frontal pole. Then we show that brain lesions & neurodegeneration that increase creativity are connected to this location jamanetwork.com/journals/jam...

I think there is a way to do exploratory research very rigorously. Just use full transparency. Publish the entire github history for the analysis chain, nits, zits, and all. And of course, focus more on the strength of evidence than posthoc narrative building.
