The Bradley Effect

<!-- start content -->
The Bradley effect, less commonly called the
Wilder effect,[1][2] is a theory proposed to explain observed
discrepancies between voter opinion polls and election outcomes in some
US government elections where a white candidate and a non-white candidate run
against each other.[3][4][5] The theory proposes that some voters
tend to tell pollsters that they are undecided or likely to vote
for a black candidate, and yet, on election day, vote for his white
opponent. It was named for Tom Bradley, an
African-American
who lost the 1982
California governor's race despite being ahead in voter polls
going into the elections.[6]
The Bradley effect theorizes that the inaccurate polls were
skewed by the phenomenon of social desirability
bias.[7][8] Specifically, some white voters give
inaccurate polling responses for fear that, by stating their true
preference, they will open themselves to criticism of racial
motivation. The reluctance to give accurate polling answers has
sometimes extended to post-election exit polls as well. The race of the pollster
conducting the interview may factor in to voters' answers
