 it's an amazing act of stage magic white supremacy has
 pulled, to transfer it's values and norms to "artificial
 intelligence" and then, because they successfully taught
 a computer to be racist (congrats i guess?) pretend that
 it is now neutral and objective and unassailable

 assorted troublemakers
 @quatoria
 like, teaching a facial recognition system to make
 judgements based on
 posting those same BS eugenics into a screed on
 livejournal in that the output of both procedures is
 identically unsound garbage - but one is called
 "objective"
 eugenicist BS is *exactly* like

Apparently, Confused, and Friends: solarmorrigan So. 10th grade English class, We all come in one morning to find a balloon and a perfectly sharpened pencil on each of our desks. No instructions, no explanation, which is strange, because our teacher is meticulous about that sort of thing A couple of people try to ask her and she says we'll get to it. She takes role and then announces that she needs to go to the copy room and she'll be back in a couple of minutes Kinda unorthodox, but no one is complaining because this is advanced English and the teacher usually goes kinda hard. So. y'know. Brief respite. We all sit and chat, one of the boys teasingly steals a girl's bailoon, but gives it back to her easily enough; it's quiet and kind of a nice break. Then the teacher comes back stops in the doorway, and just stares at us After a long moment she says, confused, "You didn't pop the balloons To which one of the guys about two rows over exclaims, "We re allowed to pop them? and immediately turms around and stabs his friend's balloon with the pencil There is a vicious revenge balloon-stabbing, and a few more people pop seatmates balloons or their own, and the whole time the teacher is just shaking her head. 1 can't believe you didn't pop your balloons Apparently we were starting Lord of the Fies that day and she wanted to demonstrate the basic concept of kids turning on each other when there are no authority figures present and it was basically my favorite failed social experiment ever vansnailismylife Back in my 10th grade we did a similar things around Lord of the Flies, where we had a test scheduled for that day, and when we walked in, the teacher took role by looking through the window of the door and never entered the classroom On the board were three tasks written and the teacher had brought in donuts. At first we all sat around and waited for the teacher to come in, but eventually we just started tackling the ist of tasks. Task 1-the test. Everybody took it silently, no one cheated, everyone turned it in and we went on to Task Two tidy up the room, So we did, we split into a couple groups and each one cleaned an area of the room. Task Three Hand out the donuts. There were 12 donuts, and 30 of us. So we split the donuts into thirds, each took a third, and left the extras for the teacher After this, the teacher came in absolutely FUMING She was so upset we had followed all the rules and completed the tasks. Apparently she had been texting kids telling them to start some chaos but they all ignored it because they were too nice She tied to dock our grades for not going absolutely wild because it meant her class didnt get the point across hookedonafeeeling That's because lord of the flies isnt representative of humanity its representative of rich white male shitheads
