Genes, talent, IQ, hardcore cold knowledge of inheritance

*It is wrong for parents who are not successful to push their children hard

*The so-called regression to the mean is too simple and misunderstood

*Marrying an excellent wife is more important than imagined

*Both parties having high IQ increases the risk

1. Talent is greatly related to parental genes

IQ, musical talent, athletic ability, etc., have a heritability rate of 50-80%; genes are not everything, but they determine the upper limit. If the parents have a strong talent pool, the child has a higher probability.

2. Boys = High leverage and high volatility stocks, girls = Stable value stocks

This is scientifically called the male greater variability hypothesis, and a large number of studies confirm: Boys have a wider distribution of traits like IQ and talent—there is a chance to far exceed their parents' upper limits (producing top geniuses), but they are also more likely to fall well below the average (higher risk).

Girls have smaller fluctuations and are more likely to be close to or slightly above their parents' average, stable and reliable.

Result: Extreme geniuses and extreme lows are mostly boys. This is the essential difference between "high risk, high reward" vs "stable appreciation"!

3. Some inheritance in boys leans more towards the mother

Boys get 100% of their X chromosome from their mother, and the Y from their father, while there are indeed many genes related to brain development and cognition on the X chromosome.

So if the father sings well and the mother is average, the son will probably sing averagely.

Daughters, on the other hand, can perfectly merge the gene combinations from both parents.

The daughter of Wang Fei and Dou Wei, Dou Jingtong, needs no guess; her musical genes are fully loaded.

4. Smart people prefer to marry smart people

Smart people are more easily attracted to other smart people and find it harder to tolerate low intelligence.

Therefore, it is true that elite talent is more likely to produce excellent talent.

5. However, in the case of extreme geniuses, they are likely to regress to the mean

Because above an IQ of 140, the higher it is, the more likely it is to encounter various mental issues like autism and depression, which seems to be a species limit set by God.
