I’ve seen people complain about google-style technical interviews, because implementing quicksort in real-time is probably not indicative of what you’ll be doing as a software engineer on the job.

Attractive women on dating apps. A man’s dating profile is a noisy signal of his value as a partner, but it’s extremely cheap for an attractive woman to just “swipe left” and try the next one. This strategy will certainly pass up people who would have made good partners, but the cost of evaluating a new profile is so low that it makes sense to just ignore any profiles that aren’t obviously great
