alt Hacker NewsWow, I guess I never thought about the "few bad apples" figure of speech! Interesting. But regardless, everyone understands what it means in common use, even if it's logically wrong, and I swear I've never seen anybody be a pedant about it here.
And really, it goes against the spirit of HN to hyperfocus on idioms instead of addressing the meat of the argument...
As a personal observation, if an LLM was figuratively looking over my shoulder and pointed out something like "well, ackshually, 'a few bad apples' means..." I would delete the fucker.
A few bad apples is a great idiom though that applies to so many places. For examples, teachers often report that more than 2 troublemakers in a classroom ruins the entire class. A few bad cops destroy trust in all policemen, ruining the the entire force, et cetera.
And more relevant to us, a couple bad lines of code sprinkled in the millions in your code base can ruin the entire thing....
