Studies like this have been repeated over and over again. This bias is well ingrained in culture. Another good one was a study where people where given a story about a successful person then asked to give adjectives to describe these people. When the person has a male name the adjectives were positive. Female names got negative adjectives. The other interesting thing is since the 1970s orchestras have used blind auditions where the person auditioning is out of view. Since then females in orchestras have increased dramatically. http://m.nber.org//papers/w5903 http://m.nber.org//papers/w5903
