Many Psychologists Now Argue That Parents' Actions Have Little Effect

Many psychologists now argue that parents' actions have little effect on their children's personality. The main evidence for this conclusion is that, on the average,

A) the personality of adopted children correlates poorly with that of their adopting parents.
B) parents with an "authoritative" style and those with a "permissive" style have children with about the same personality.
C) children's personality does not vary between one culture and another, or one generation and another.
D) first-born children develop significant personality differences from their later-born brothers and sisters.
