Hence the supply of "good" ESTJs is much larger than the supply of "good" ENTJs simply because there are more ESTJs than ENTJs.
Surprisingly, 65% of INTJs rated “home and family” as “very important”.
This percentage however, while appearing high, was still relatively low when compared with other types.
INTJs, in addition to reporting the lowest satisfaction in relationships, also rate them as being the least in importance of all the types.
In another study (Myers, Mc Caulley, Quenk & Hammer, 1998) only 30% of INTJs rated relationships/friendships as “very important”.
Commonality implies a wider variety of choices and better opportunities for good type development.
Rarity implies less choice, and it is often harder for rare types to achieve good type development.
Despite their rarity, it has been found that INTJs are more likely than average to marry other INTJs.
According to another study (Marioles, Strickert & Hammer, 1996) male INTJs were 3.85 times more likely than average to marry a female INTJ, while female INTJs were 2.22 times more likely than average to marry a male INTJ.
So just remember: Ever since Keirsey published Please Understand Me II in 1998, it has generally been accepted that the Rationals are the best partners for the Idealists.
This appears to be true--at least from the Rational point of view.
On the internet, one of the Idealist types that INFPs seem to gravitate towards is the ENFJ Teacher.
