That's not actually true. If you look at personality tests based on Big 5/Neo-Pi, which are the most accepted in psychology, scores on conscientiousness and the underlying factors like "order" can be completely opposite to the parents

Yes, "can". Because we are not clones of our parents. It doesn't mean that conscientiousness hasn't something like 60-80%of hereditability.

again, that's not true. It can be argued that it can't be proven beyong 50%, which means that it's a toss-up and parents with low conscientiousness have children with high scores. Also, this trait is not indicative to success, even if it correlates. Too high is also a negative, just as too low is.

Studies say 20-70% for different measures.
