>>11241977below 90: Irrelevant brainlets who have to rote memorize to learn things. Have trouble doing office drone jobs.
90-100: Brainlets who don't care about intelligence, except when they think it gets them a better reputation among their peers. Have trouble with abstractions. Are easily deceived into becoming extremists (example: most /pol/tards)
100-110: Normalfags, their life is defined entirely by fitting in into their surroundings and mimicking what other "normal" people are doing. Are afraid of anyone or anything that is different from what they are used to.
110-120: Pseudo intellectuals who are all talk but actually don't understand shit, "Very Serious People". King of brainlets. Mask their deficit of intelligence through unnecessary complex choice of words.
120-130: Somewhat intelligent, the average /sci/ stemfag. Too smart to be part of the lower groups, but not smart enough to be exceptional. Uses "critical thinking" almost constantly, for the lower tiers this is a learned skill.
130+: Can do actually impressive things (you likely aren't here if your main occupation is wasting your life on 4chan, these people have more interesting stuff to do than shitposting.)
