alt Hacker News> And how exactly is that surprising?
Isn't the point of a lot of science to empirically demonstrate results which we'd otherwise take for granted as intuitive/obvious? Maybe in AI-literature-land everything published is supposed to be novel/surprising, but that doesn't encompass all of research, last I checked.
If the title of your study both makes a neurotoxin reference ("This is your brain on drugs", egg, pan, plus pearl-clutching) AND introduces a concept stolen and abused from IT and economics (cognitive debt? Implies repayment and 'refactoring', that is not what they mean, though) ... I expect a bit more than 'we tested this very obvious common sense thing, and lo and behold, it is just as a five year old would have predicted.'
