It’s very easy to send one course back (or even one after another, after another, after another) when the menu is overflowing with other potential courses. The US Association of Psychological Science found that reviewing multiple candidates causes people to be more judgmental, and inclined to dismiss a not-quite-perfect candidate than they otherwise would be in a face-to-face meeting.
With that in mind, it shouldn't come as any surprise to learn that research regarding Personality Type and Relationships shows a definite pattern which indicates that successful mates often share the same dominant function, and the same letter preference ("S" or "N") for their information gathering function. Of course, that does not mean that people with different preferences cannot have a happy, successful marriage, it simply indicates that people frequently settle down with individuals who are on their same "wave-length".
