ExTJs (particularly ESTJs)
Why don't we do a (rather inconclusive) study:
Were you spanked as child?
Which parent did the spanking?
What was said parent's type?
And btw, to the OP who thinks that spanking = sick/disgusting. Spankings can go far if they are used in a healthy way. Not all spankings => red tomato bottom that the kid can't sit on for a week. Spanking != beating. Of course there are other modes of disciplining a child, but this one is not completely evil and ineffective.
