āLove Languagesā are just common couples therapy techniques mangled and repackaged by an unqualified homophobe. Relationships generally need all 5 love languages to be fulfilled, which is to say, everybody needs to communicate with, spend time with, and do things for their partners, and thatās got nothing to do with any special way you communicate affection.
MBTI has been proven completely ineffective at predicting anyoneās 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 donāt adhere to strict binaries in basically anything. Very few people are going to be exclusively introverted or extroverted. Itās just astrology repackaged as pseudoscience. Shockingly enough, you canāt boil the complexity of the human experience down to a dozen Types of Guy.
The concept of IQ is flawed from the startā āintelligenceā 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, itās also a pretty good predictor of income and education level, take a guess why. Most peopleās IQ will change throughout their lives, because itās inconsistent bullshit weāve only held onto this long because weāre 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. Itās intended to give a rough estimate of obesity in populations, and itās 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 peopleās 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.
If you havenāt put together what all these things have in common yet, hereās the moral of the story: STOP TRYING TO CATEGORIZE PEOPLE. STOP TRYING TO PUT PEOPLE IN A GODDAMN BIOLOGICAL HIERARCHY. EUGENICS IS BAD, AND WILL ALWAYS BE BAD, NO MATTER WHOāS DOING IT.
