>>13052846>describes an individuals performanceHow does it do that when IQ result is measuring from a bell curve of results.
You are comparing an individual to every other person within the sample.
The result is dependent on the quality of the sample of people performing the test.
I.e. if I do an IQ test against and score 150 that doesn't mean I am necessarily smart, it just means that I scored well against everyone else.
I have never seen one IQ test that releases their exact sampling techniques, it's usually just some hand wavey bs.
There is this incorrect assumption that if you do large enough samples, the result is more accurate.
Large enough samples from where? Do you account for their background?
What about stress levels due to external factors?
The cope that IQ predicts success is a meme. By how do you measure success.
Financial success? Okay so a plumber that runs his own business that has no academic history and scores lower than someone on this board likely earns a lot more money than people on here?
I understand that's anecdotal, but these are the questions I haven't seen psychologists address. Usually they just circle back to "large enough results show that it's correlated", without addressing how it's been sampled and controlled.
