THE MANEATER - Oct 10 - Psychologist and anthropologist Helen Fisher was a part of the Life Sciences & Society symposium, The Science of Love, in which speakers were sharing research about the biology and chemistry behind love. Fisher worked with match.com in 2005 when she was hired to create chemistry.com, which combined hormone and personality-based matching systems. Romantic love is linked to a sense of attachment that is triggered through the chemicals oxytocin and vasopressin in the brain. This feeling can also be connected to sex drive. Fisher doesn't see dating sites as sites that facilitate dating. They're more like introducing sites, she said. A matching system isn't always right. "The only true algorithm is your own brain," Fisher said.
