The best we can say is that one study found that female ENFJs had a very very high attraction for male ENFJs--the highest attraction found for any type pairing.
Male ENFJs had a particularly high, but not over the top, attraction for female ENFJs.
Idealists gave the lowest ratings of all to Artisans (51%) and Guardians (46%).
It seems that Idealists strongly prefer other intuitives.
Compared to other types, the Idealists appear to have the most to lose if they make a wrong choice.
Please bear in mind that none of this has to be a stereotype that rules your life. They were happy together, but according to Isabel's own type theory they weren't predicted to be perfect for each other.
You're a unique individual with a unique background, and this description is simply a generalization based on statistics and averages. Later on, Myers said that if she had known about type theory, she probably wouldn't have married Chief. There is a lesson to be learned here: type is not everything, nor should it be the decisive factor in choosing your lifemate. Then too, the connections between type, attraction, love and marriage haven't been well studied yet. Tieger and Baron-Tieger (2000) found that Idealist-Idealist pairings have an average satisfaction rate of 73%--the highest attraction rating for all the NF pairings, and almost the highest possible satisfaction for all pairings. Green = Guardian, Blue = Idealist, Purple = Artisan, and Teal = Rational.
Don't take what you read here as , but as an invitation to grow outside your core strengths. (The question is more complicated than you'd think.) You can read about this question and the various attempts to answer it here. As a further note, the Rationals had a higher satisfaction with an NF mate than with any other temperament. Now, it is a mistake to generalize by temperament--it’s frequent that types will go counter-temperament, and temperament is not the definitive factor in explaining type-based behavior most of the time (CITE)--but since we don’t have anything better to go on...
And especially don't use this description as an excuse. 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.
Isabel Myers (INFP) married a man named Chief, an ISTJ and a good man.
This appears to be true--at least from the Rational point of view.
The Idealists, however, actually tend to be more satisfied with other Idealists.
But Rationals are the second favorite choice for the Idealists.
