Keirsey (1998) described INTJ parenthood as a carefully researched and prepared strategy. INTJ parents, he notes, will have read everything available on child rearing, digested the information, formed their own conclusions, built a plan, and will carry it out. Like all Rational parents, they have a tendency towards sternness, and this tendency is stronger for Judgers.
Penley (2006) has noted that INTJs parents seldom create traditional roles for themselves or their children. "Everybody else gets to do this, everyone else has this toy, everyone else is going," the children may whine, but the INTJ parent will not be moved by such peer pressure. INTJs tend to expect from their children the same qualities that they themselves exhibit: autonomy, achievement, a willingless to think critically, and perseverance.
A study found that while a large chunk (65.1%) of INTJs rated "Home and family" as one of their most important values, they nevertheless placed the least weight on it of all types (Myers et al., 1998). Homemaking by itself is unlikely to meet an INTJ's intense desire for achievement; therefore some balance between the familial sphere and the project sphere is called for. However, if not careful, they may later regret time not spent with loved ones.
One particularly in depth look at an INTJ's parenting style is provided by the two sequels to the book "The Three Musketeers." Though the sequels were not as good as the first book, the interactions between the Musketeer Athos and his son provide a good example of the stern but loving style of the INTJ parent.
