Forgot to add this basic rule:
Dumb people have dumb kids
Average people have average kids
High IQ people don’t have kids
Not true. Most geniuses have kids and most are not geniuses. True genius is a rare anomaly and is just as likely
to appear in families if average intelligence as in families if high IQs. In addition, high IQ is a matter of opinion, easily manipulated. Most people who claim to have high IQs don’t. They are quite average but tend to be supercilious.
Have you ever heard iof regression toward the mean?
Not only that, IQ is subjective- for example, one can take an IQ test in France, move to the States or Great Britain or wherever, learn the language well, yet score lower on an IQ test in that country. At the same time, one can have a good night’s sleep, eat a good breakfast, etc and score very well on an IQ test, but come in to take the test another day, not sleep well, skip breakfast and score lower. That said, parents can have an above average IQ and have a gifted child, while the other child, not be gifted, but average IQ, yet score exceptionally high or even gifted in physical abilities or artistic ability- which is another form of intelligence (forgot the name of the psychologist who came up with these forms of IQ).
