'OKCupid' admits to manipulating compatibility

The dating website OKCupid admits manipulating cupid's arrow when it experimented on its users.

The site says it told some couples they were highly compatible when they actually were not.

OKCupid says these users were more inclined to actually like each other when they were told to.

Facebook recently came under fire for also tinkering with its algorithms as part of a social experiment.
