Biases in the Perception of Barack Obama's Skin Tone

White Americans higher in prejudice were less likely to vote for Barack Obama than other Americans. Recent research also demonstrated that supporters and opponents of Mr. Obama engaged in skin tone biases, i.e., they perceive Mr. Obama's skin tone as lighter or darker in line with more positive or negative views of him. Across two studies we hypothesized that skin tone biases occur as a function of two independent sources: racial prejudice, which is always related to skin tone bias, and political partisanship, which is related to skin tone bias primarily during elections. Study 1 assessed perceptions of Mr. Obama's skin tone shortly before and after the 2008 Presidential election, and shortly after the first inauguration. Study 2 assessed perceptions in the middle of his first term, immediately prior to the 2012 Presidential election, and 1 year into his second term in office. Consistent with our hypothesis, we found that partisan skin tone bias was limited to the election period, whereas prejudice-based skin tone biases occurred independent from any election.
