Obviously a culture will impact behavior once it's ingrained. But at a very young age, children's personalities will differ vastly even before "core memories" or "parental interactions" will have had a chance to form them. The question is not whether "Nature" or "Nurture" have an impact, it's whether and which one of them is dominant overall, and whether and which one of them is dominant for specific behavioral traits. We certainly do not have an answer to either of those questions.
