Parental support influences personality
If parents have more than one child, the level of support, i.e., the amount of time spent or the parenting style, may differ for each sibling. How does this affect the children’s personalities? Data from “Life in Germany” shows that key personality traits vary among siblings who have received different levels of support from their parents. Birth order does not play a significant role in this.
Incidentally, the effect of parental influence weakens in early adulthood.
