There's this thing in public opinion where whatever people are mad about, they also overestimate how common it is by like a crazy amount.
Off the top of my head people think we should stop giving away so much money to poorer countries. Ask them how much of the budget goes to aid, they'll say something nuts like 20% when it's actually like 1%.
I haven't done this experiment in person but I bet I'd get a pretty ludicrous answer if we asked what percent of us are trans.
And it'd be pretty easy to debunk too. "oh you think it's 10%? So count the next ten customers to walk in. You think you typically serve a trans customer before 9am, and never noticed it?"
"......uh well maybe not 1/10. Maybe more like 1/100".
Where this is all going: you can convince a person that they are off by a crazy large amount fairly easily but you can never ever convince a person they're wrong.
Does this mean convincing people to be less enthusiastic about their wrong opinion is more viable than getting them to abandon wrong opinions?
Next time my facebook coworker screeds on the mythical girl who identifies as a cat and carries a litter box to school, I'm going to test his estimates. I bet I can't change his mind but I bet I can get him to be quieter.
Last I saw the data, based on self identification, was .6% of the population was "trans," put in quotes because it wasn't totally clear what that included I think it included nonbinary people though. Personally I think that if you got rid of all social stigma, probably ~5% would identify as "hard" trans with another ~5% as some variation of "softer" trans identity; using hard and soft here not to distinguish specific kinds of gender variance but more of how strongly a person feels about their gendered identity as not conforming to their assigned gender.
