A "New" Theory on Sexual Orientation

From The Advocate:
A Northern California author says he's discovered the missing link that explains the biological source of sexual orientation. While doing research for his recent book, The Whole-Brain Path to Peace, James Olson stumbled upon what he says is the direct correlation between hemispheric dominance in the brain and whether a person is gay or straight.

Olson’s theory portends that both heterosexual men and lesbians are generally dominated by the left hemisphere of the brain, which is committed to sequential, thought-oriented processes. And heterosexual women and gay men are much more likely to be dominated by the right hemisphere of the brain, which regulates feeling and cultural awareness.

Olson believes that current research looking for a “gay gene” is searching in the wrong place. Rather, Olson contends, sexual orientation is determined by brain hemisphere dominance. Most men are left-brain dominant, whereas most women are right-brain dominant. Seizing on the implication that “most” necessarily excludes some people, Olson wondered what happened when brain dominance was reversed from the standard.
Yet another theory that points to sexual orientation being innate, not chosen. Personally, I would like to see where theory on this research goes in the future.
