Steretypes really do have an impact on results a new study reveals. A new ABC study shows us that before taking an exam you really shouldn’t watch ditzy females on television. The study showed that women who watched commercials with stereotypical ditzy females before taking a math test scored 38 percent lower than women who didn’t see the ads. The study also revealed that Asians, when reminded they do well in math, actually perform better in school. The study also revealed you could control a black person’s test scores prior to taking a test by telling he or she how they’ll perform.
