Bisexuality is proven by science

The argument

The scientific case that bisexuality exists begins with the foundational research on human sexuality itself. When Alfred Kinsey surveyed thousands of Americans in the 1940s and 1950s, he found that sexual orientation did not divide neatly into two boxes; he placed it on a seven-point scale running from exclusively heterosexual to exclusively homosexual, with most people falling somewhere between the poles. The very structure of his findings implied that attraction to more than one sex is not an anomaly but a substantial middle of the distribution — exactly where bisexuality lives. Later research has reinforced rather than overturned that picture. Large national health surveys consistently record more people identifying as bisexual than as exclusively gay or lesbian, and the proportion rises among younger respondents. Studies of attraction, behaviour and identity find the three do not always line up, and that a meaningful share of people report genuine attraction to more than one gender across their lives. Psychological and physiological studies designed specifically to test whether bisexual men show arousal patterns matching their stated identity have, in more recent and better-designed work, found that they do — addressing an earlier study that had been used to question bisexuality's existence. The convergence of self-report, behaviour and laboratory measurement points one way. Sexuality is better described as a spectrum than as a binary, and a spectrum necessarily includes the middle. Bisexual people are not confused, transitioning or concealing another orientation; they occupy a real and well-populated region of the range of human attraction. Because the science describes sexuality as a continuum rather than two discrete categories, this argument concludes, bisexuality exists.
