I don't think that's the case; I have a son who has been a "Guesser" from a fairly young age, despite our family encouraging people to be "Askers" all of his siblings are "Askers" and can't understand why he won't ask for things that he wants.

For completeness sake, I should point out that most of our kids (including this one) are adopted so it's not impossible that there could be a genetic predisposition to being an asker or guesser.
