    Default Is type inherited?

    Has anyone read any studies on whether type is related to inheritance/genes? It is interesting to me that identical twins often have very different personalities, despite the fact that type seems to be "inborn" in us.

    If MBTI follows Big 5 (and they do correlate reasonably well), then the heritability of each dichotomy should be around 40%-60%.

    That seems about right. Can you elaborate?

    If it is inherited, so I'm the X-men of the family. INFP surrounded by ESFJ's, ISFJ's, ESTJ's and ISTJ's...

    Yeah it's far from easy... "You slacker! Go clean your room! Stop imagining things and work more!"

    If the types do not result exclusively from the circumstances of one's socialization (which is fairly unlikely), they must at least partially be inherited.

    Somewhat of the same issue. I'm more independent in my decision making, less busy bee, messier, and I don't seem to care about many of the aspirations and obligations I'm "supposed" to care about. My dad thinks he's somehow done something wrong with my upbringing.. (even though we get along). I don't seem to "get it". Whatever "it" is.

    Sure... from the wikipedia page on the Big 5:

    Openness [N/S]: 57%
    Conscientiousness [J/P]: 49%
    Extraversion [E/I]: 54%
    Agreeableness [F/T]: 42%
    Neuroticism [no MBTI equiv]: 48%
    (correlated MBTI dichotomies added) The MBTI dichotomies are correlated, but not a perfect match for their Big 5 equivalents.

    No, that would be 0% inherited, meaning that inheritance has no effect. Also, keep in mind that the Big 5 traits are measured along a continuum, rather than being a binary choice. So, for example, having one highly extraverted parent and one mildly extraverted parent would still be measured and taken into account.
