A professor from the Kellogg School of Management wondered: what rules do the bouncers at exclusive night clubs use to filter some clientele into the club and leave others out in the cold?
Bouncers weighed each cue differently. Social network mattered most, gender followed. For example, a young woman in jeans stood a higher chance of entrance than a well-dressed man. And an elegantly dressed black man stood little chance of getting in unless he knew someone special.
