Can't you just ignore the polls on this one and go with your instinct?
A joke about an overly-analytical person who makes all their decisions based on data/polls, so much so, that she has hired an entire team of people to crunch the numbers on all their decisions. Her partner is begging her not to over-analyze their feelings for each-other, and go with her instinct instead. It's funny because some people over-analyze relationship situations, and this person takes it to an extreme.
