A new study in Acta Psychologica reveals that schooling largely explains IQ differences in identical twins raised apart. When their educations are very dissimilar, their IQ scores can be as different as those between complete strangers.
The problems found on an IQ test are of a very specific nature. “Complete the following number sequence”, “Which of these shapes doesn’t belong”, etc.
A full IQ test has more kinds of problems than that, some of them more open ended and with multiple possible answers. It’s still kind of a mess, the tests need to be kept secret to have any value, and the interpretations of what is a valid answer, are sometimes dubious.
