alt Hacker NewsI'm either not seeing something or I do not see the point of this study.
Amount of "critical thinking" is basically amount of oversight, no? What's interesting is when the amount of oversight is inappropriate, leading to overconfidence in bad results (or, if too much oversight, lack of efficiency).
This paper does not seem to discuss results and correctness at all, ONLY the amount of critical thinking.
I'm going to assume you're being serious.
Critical thinking is actually something that people exercise (or don't) all the time. It is a skill and practice that is inarguably valuable in all situations. This paper is not about the effects of critical thinking on "AI results", but the exact inverse of that.
Do you value the capacity for critical thinking in yourself? In others? If so, the effect reported by this paper is probably of interest to you.
