From Kohl et al. (2001)Originally Posted by surfs_up
The ‘affective primacy hypothesis’ [5] asserts that positive and
negative affective reactions can be evoked with minimal stimulus input and virtually no cognitive processing.
Olfactory signals seem to induce emotional reactions whether or not a chemical stimulus is consciously perceived. We
theorize that the importance of human non-verbal signals is based upon information processing, which occurs in the
limbic system, and without any cognitive (cortical) assessment. Affect thus does not require conscious
interpretation of signal content. Underlying this fact is that affect dominates social interaction and it is the
major currency in social interactions [6]. Affective reactions can occur without extensive perceptual and cognitive
encoding. They are made with greater confi dence than cognitive judgments, and can be made sooner [5, 7]. Olfactory
input from the social environment is well adapted to fit such assertions. For example, chemical cues allow humans to
select for, and to mate for, traits of reproductive fitness that cannot be assessed simply from visual
cues.
My compliments to Gladwell, whose viewsOriginally Posted by surfs_up
are more clearly stated and more readily understood than mine. Here's a link to a recent report on these "snap
judgements" that also mentions Gladwell's
book.

With this recent report in mind, please consider that a sex difference in the signal, and in its processing are
required to get to sex difference in behavior. Following this biological logic, the only way to get to sex
differences is through olfactory /pheromonal conditioning of the visual response that allows us to make "snap
judgements." The article linked above mentions functional MRI, which has been used to show sex differences in the
response to pheromones, and sexual orientation differences in the response to
pheromones.
