So much has been built upon this framework in psychology and decision making that it’s probably work reading Thinking Fast and Slow. Not all of it has survived the replication crisis (in particular some of the experiments on priming) but much is still relevant.

my reading of it is that system 1 is instinctual and system 2 is intellectual, but of course the boundaries are blurry and arbitrarily defined.

Nice, I'm a nondualist too. Yeah it's a strange delineation into "good" system 2 and "bad" system 1.

I don't think the Nobel committee have a monopoly on picking good or bad ideas ;)
