"Gendering. We all do it. We meet someone, and automatically categorize
them as being male or female. We add up both obvious and subtle cues
to figure out which sex they are. Maybe we have good gaydar skills,
and further identify them as gay or lesbian. This is a useful skill,
especially if we're single and looking for a potential partner, or
perhaps a date for this weekend. Maybe we also have good transdar
skills, and can even identify the person as having a transgender
history, someone who has lived as a different gender in the past."
