Falsehoods Programmers Believe About Gender
  1. There are two and only two genders.
  2. Okay, then there are two and only two biological genders.
  3. Gender is determined solely by biology.
  4. Okay, it’s mostly determined by biology, right?
  5. Please tell me it’s determined by DNA.
  6. Gender can be reliably determined through visual means. After all, no man would ever wear a burka.
  7. Once gender is set, it never changes.
  8. Even if the gender can change, it will only change from the one value to the other value.
  9. Only one gender can be “active” at the same time.
  10. We’re tracking gender now, so we’ve always tracked it.
