alt Hacker NewsIt's just incredible to me that Blade Runner predicted this in literally the very first scene of the movie. The whole thing's about telling humans from robots! Albeit rather more dramatically than the stakes for any of us in front of our laptop I'd imagine

The fictitious Voight-Kampff test is based on a real machine based on terrible pseudo-science that was used in the 1960s to allegedly detect homosexuals working in Canadian public service so they could be purged. The line from the movie where Rachel asks if Deckard is trying to determine whether she is a replicant or a lesbian may be an allusion to the fruit machine. One of its features was measuring eye dilation, just as depicted in the movie:

The stakes for men subjected to the test were the loss of their livelihoods, public shaming, and ostracism. So... Blade Runner was not just predicting the future, it was describing the world Philip K. Dick lived in when he wrote "Do Androids Dream of Electric Sheep" in the late 1960s.
What was once science fiction is bound to become science fact (or at least proven it can never be done).
Hollywood has gotten hate mail since the 70s for their lack of science research in movies and shows. The big blockbuster hits actually spent money to get the science “plausible”.
Sidney Perkowitz has a book called Hollywood Science [0] that goes into detail into more than 100 movies, worth a read.
