The woman who made online dating a science

The anthropologist and famed love expert Helen Fisher seems ready to dash into oncoming traffic. We are on a sidewalk in Manhattan, opposite the American Museum of Natural History, and nowhere near a safe place to cross the street. She wants me to stare down the yellow cabs and charge off the curb, though she knows I won’t do it: I’d recently taken the personality questionnaire she wrote 17 years ago for a dating website, which produced the insight that I am a cautious, conventional rule follower. She, however, is an “explorer” – she has visited 111 countries, including North Korea – but also, being high in estrogen, a “negotiator” who will use the crosswalk for my benefit.
