Well when you have one bad egg in an otherwise good group, you punish the group to enforce better behavior in the individual.
Uhhhhhh....No you don't. That's a stupid idea.
Every single time that happened in grade/high school, it NEVER produced that result.
The result was either
a) The entire class going "Oh my GOD the teacher is such a jerk dictator, they KNOW who the troublemaker was but they're punishing ALL of us, this is bullshit! Why do WE all have to write an apology essay when were were actually doing the class work?!" (IE, everyone blames the moderator instead of the actual guilty party)
b) The teacher going "I will punish you all until the one who did it admits they did it!" "It's dude over there!" "NO I WANT HIM TO ADMIT IT, besides I can't be sure that you're lying" (Guy basically lolnopes), cycle back to situation a) or now everyone is pissed because there's no way to get out of bieng unjustly punished.
c) "Hey Aegix, YOU say you did it!" "What, but I didn't do anything!" "Yeah but no one likes you anyway you little (expletive), so you should be useful for once and be the only one to be punished!" (Nobody disagrees, several of the assholes in class are nodding along)
The BEST scenario I saw was, after about 10 minutes of letting us stew in silence after yelling that "whoever did it and isn't admitting it is a chickenshit coward", the teacher finally came in and was like "Still no one is admitting it? Wow. STILL a chickenshit coward! Alright, I know it was one of YOU four jerks over there, you four come to the office", which was better than every other time. Still, it WAS the time that situation C happened to me, so it's a sour moment nonetheless.
Now look, I GET why this is a thing, it's supposed to cause social pressure to out the actual perpetrator...But it rarely ever works that way. If the one who did it is a bully/jerk/chronic troublemaker/popular kid, it doesn't change their attitude or everyone is too scared to pressure them. If it's an unpopular person or someone who isn't a strong personality, even if they admit they did it and get the group out of their punishment, the group will STILL hold it against them.
That and it promotes vigilante punishment by "the mob", especially in cases where it's an unpopular kid who causes the trouble, which isn't really a good thing. Worse still it can be weaponized in ways that hurt everyone BUT the guilty party.
Thank you for coming to my ted talk.
