The machine could figure out who the most desirable people in the bunch were based on certain characteristics like physical attractiveness, Joel says. But when it came to predicting which people would be a good fit for each other, the machine failed spectacularly.
“It predicted 0 percent [of the matches.] Some of the models we ran got a negative percentage, which means you’re better off just guessing,” Joel says. “I was really surprised. I thought we would be able to predict at least some portion of the variance — like extroverts or liberals like each other.”
The result is a little unnerving to scientists, too. [npr]
