Summary

Psychologist Julia Shaw explains bisexuality to Lex Fridman, drawing on her book Bi: The Hidden Culture, History, and Science of Bisexuality and her bisexual research group. She covers research terminology, what bisexuality actually means, and the history of Alfred Kinsey's post-war sexuality research and the Kinsey Scale. She concludes that the biggest misconception is that bisexuality is a phase, and that bisexual men in particular face pressure to identify as gay or straight, including from within queer communities.

Key points

  • Julia Shaw wrote Bi: The Hidden Culture, History, and Science of Bisexuality after founding a bisexual research group.
  • Researchers sometimes use terms like plurisexual, omnisexual, and pansexual instead of bisexual.
  • Shaw describes bisexuality as being able to be attracted to people regardless of gender, not being attracted to everyone.
  • The biggest misconception is that bisexuality is a phase or a stepping stone toward being gay.
  • Alfred Kinsey's post-WWII research found most people were not exclusively heterosexual or homosexual.
  • The Kinsey Scale runs from zero to six, and about half of men fell somewhere in the middle.
  • Bisexual men often find it easier to identify as gay or straight, partly due to queerphobia within queer communities.
  • Bisexual women are often seen as performative, as doing it for men's attention.

Questions it answers

00:00Bisexual research and terminology

Why did Julia Shaw write a book about bisexuality, and what terminology do researchers use?

She wrote Bi: The Hidden Culture, History, and Science of Bisexuality after founding a bisexual research group, and found the science of bisexuality hard to locate. Researchers often use terms like plurisexual and omnisexual instead of bisexual.

  • Searching "bisexual" on Google Scholar yields confusing results.
  • Plurisexual, omnisexual, and pansexual are alternative research terms.

01:06How to think about bisexuality

Is bisexuality about being attracted to everyone, or something else?

Shaw says she is not attracted to most people but can be attracted to people regardless of gender. The pool of potential partners is like anyone else's; gender is simply irrelevant.

  • Bisexuality is not day-to-day fluidity or universal attraction.
  • Gender is irrelevant rather than determinative.

02:06The 'phase' misconception

What do people most misunderstand about bisexuality?

The biggest misunderstanding is that it is a phase or a stepping stone toward being gay, especially for men. Historically, research focused on bisexual men, though today twice as many women identify as bi as men.

  • Bisexuality is often seen as "on the way to Gay Town."
  • The gender balance of bisexual identification has shifted over time.

02:48Alfred Kinsey's research

How did Alfred Kinsey start researching human sexuality?

Kinsey, a biologist studying gall wasps, was asked to teach a class on human sexual behavior after WWII. After a year collecting student questions he found the research didn't exist, so he and assistants interviewed thousands of Americans in the 1940s.

  • His book Sexual Behavior in the Human Male was a best-seller for a year.
  • His lectures were so popular extra halls were linked by radio.

05:00The Kinsey Scale

What is the Kinsey Scale and what did it find?

The scale runs from zero (exclusively heterosexual) to six (exclusively homosexual). Kinsey found most people were not at either extreme: about half of men and about a quarter of women fell somewhere in the middle.

  • A binary was not useful for describing sexual orientation.
  • Homosocial environments like war and prisons affected behavior.

07:12Queerphobia within queer communities

Why do bisexual men often not identify as bi?

Bisexual men often find it easier to identify as gay or straight. Queerphobia exists within queer communities, with gay men saying "I was bi once," while bisexual women are dismissed as performative and doing it for men's attention.

  • Saying you're bi can be problematic in both gay and lesbian communities.
  • The hostility is different in nature for bi men and bi women.

Notes

Terminology and research

  • Julia Shaw wrote *Bi: The Hidden Culture, History, and Science of Bisexuality* after creating a bisexual research group.
  • Searching Google Scholar for "bisexual" gives confusing results because the word is also used for organisms with multiple sexes.
  • Researchers use alternative terms like plurisexual, omnisexual, and pansexual; plurisexual is the most useful for finding research.

What bisexuality means

  • Shaw is not attracted to most people, but can be attracted to people regardless of gender.
  • Gender is irrelevant to attraction, unlike for people attracted to a specific gender.

Common misconceptions

  • The biggest misunderstanding is that bisexuality is a phase, transient, or a stepping stone toward being gay.
  • Today twice as many women identify as bisexual as men, but historically research focused on bisexual men.

Alfred Kinsey

  • Kinsey was a biologist researching gall wasps who was asked to teach a class on human sexual behavior after World War II.
  • He spent a year collecting students' questions, found the research didn't exist, and then interviewed thousands of Americans.
  • His book *Sexual Behavior in the Human Male* was a best-seller for a year; his lectures were so popular extra halls were connected by radio.
  • The Kinsey Scale runs from zero (exclusively heterosexual) to six (exclusively homosexual).
  • About half of men and about a quarter of women fell somewhere in the middle rather than at either end.
  • Homosocial environments like prisons and war changed people's available options and behavior.

Social pressures on bisexual people

  • In the 1970s the pattern shifted, and bisexuality became seen as more of a women's thing.
  • Bisexual men often find it easier to identify as gay or straight.
  • Queerphobia exists within queer communities: gay men say "I was bi once" to bi men.
  • Bisexual women are often seen as performative, assumed to be doing it for men's attention.
