I read about a different study some time ago (apologies, I've completely forgotten the title, authors or even field) which basically said that twins separated at birth ended up with relatively similar abilities and personalities regardless of whether they were raised in different households with different income levels, parenting styles, diets, etc.

In other words, much of it comes down to genetics. I have no idea the relevance of this idea or even of its validity, but it makes me wonder if the causation they speak of here between parents of a certain personality and their children has any ties to the inherited genetic characteristics rather than the nurturing of the child.

And yes, some of your personality traits may have been affected, but you will be a different person every 5 years anyway; walk in that direction and you will get closer to where you want to be.
