I’m writing some queer, anti jkr, fix-it-fic harry potter oneshots, published the first one last night

it’s what i think should have happened the night lily and james got murdered.

MBTI has been proven completely ineffective at predicting anyone’s success at a particular job, and half the people who take it twice will get different results. Reputable psychologists do not recognize it, and the company that owns the rights to it uses it to scam people. People don’t adhere to strict binaries in basically anything. Very few people are going to be exclusively introverted or extroverted. It’s just astrology repackaged as pseudoscience. Shockingly enough, you can’t boil the complexity of the human experience down to a dozen Types of Guy.

The concept of IQ is flawed from the start— “intelligence” is an abstract concept that encompasses many different skills, from social intelligence to emotional intelligence to the very narrow kind of problem solving intelligence IQ tests generally measure for. It cannot predict how fast you learn, how much you know, or how logical and well read you are. It mostly measures how good you are at solving puzzles. Coincidentally, it’s also a pretty good predictor of income and education level, take a guess why. Most people’s IQ will change throughout their lives, because it’s inconsistent bullshit we’ve only held onto this long because we’re still kinda hoping we can breed the ubermensch. IQ tests and the way they attempt to categorize people are explicitly eugenicist and racist.

BMI was developed by a man known as the grandfather of eugenics, who first of all was a mathematician, not a doctor, and second never intended the formula to be used to categorize individuals. It’s intended to give a rough estimate of obesity in populations, and it’s not even good at that. It hangs around because of fatphobia and insurance companies who want it as an excuse to charge fat people more.

The study which determined people’s prefrontal cortex was still developing at 25… stopped measuring at 25. Evidence suggests your brain probably never stops developing. Stop infantilizing grown adults. This is a branch off from the larger mess of misinformation surrounding fMRIs.
