I don't have one. I was just seeing if there was any obvious relationship.
There are lots of Feeler mothers reported (although Economica is an exception).
There's an old pop psychology hypothesis that overly protective or controlling parents (particularly the main nurturing parent) will make a child feel smothered and wanting to seek more independence. On the other hand, a primary nurturing parent who is distant or emotionally cool supposedly results in a clingy, needy kid.
Obviously it's not a hard and fast rule. The degree to which a child feels either "smothered" or "abandoned" (and hence turn out independent or clingy) can be affected by lots of things; number of siblings, birth order among siblings, childhood illnesses or traumas, etc.
But it's worth bringing up the hypothesis, given all the INTJs reporting Feeler (IOW presumably relatively protective or "smothering") mothers.
