Positive vs zero sum
There's a lot of talk of "zero-sum bias": believing situations that aren't zero-sum (e.g. trade) to be so.— Stefan Schubert (@StefanFSchubert) May 31, 2020
But seems there's also the opposite "positive-sum bias".
E.g. cf the notion that "all should get a prize".
Seems to rest on confusion that prizes are not zero-sum.
