What other psychological reasons could underly this phenomenon?
Can only guess what lurks in people's minds.
My speculations are only that & aren't meant to defend or justify.
Think that many folks want to know which (one or the other) gender someone is attracted to, it's a shorthand for getting to know someone (like asking what someone's job is or what their positions are on sports, politics, religion, social issues)-
Straight person (S) worries that Bi person (B) is attracted to the straight person (him or her self).
S worries that B is not attracted to S, even though S isn't attracted to B.
S worries that B is attracted to same gender that S is attracted to, which makes B competition for mate.
Frustration or anxiety at not being able to pin person down (figuratively) in simple terms (such as gay or straight-instead this person is "having it both ways"). Not being able to know what to expect (though of course I don't see why a straight or gay person is somehow considered predictable)-bisexuality seems even more "up in the air", confusing, to someone who can't imagine how someone could be "both straight & gay", so to speak.
Believe that being bisexual is a valid trait or way of being (I consider it just as "natural" as being straight or gay), but can understand to some extent how others may have difficulty wrapping their brains around the concept. One could compare this desire to put people in either this box or that box to many other aspects of being human, such as race ("passing" for this or that ethnicity if one has skin color that's in-between), neurological status (autism, ASD dx or NT-and where do we draw the line, what's threshold for which grouping ?), or gender itself (androgenous appearance or mannerisms).
