In a widely read study, business school students were given a case assignment on Heidi, a real-life successful entrepreneur in Silicon Valley. But there was a catch. Half of the class randomly received their case with one teensy tiny change made: The name "Heidi" was changed to "Howard." Afterward, the students were surveyed, and though Heidi and Howard were found equally competent (as they should have been because they are the same person), the students found Howard much more likeable. The following ad pretty much sums up why.
