Increasingly large minority populations in US may have contributed to Trump's victory in other ways

Donald Trump’s presidential victory took many by surprise, and in the weeks since the election, political analysts have attempted to understand who voted for Trump and why election forecasts were so wrong. One might wonder how a country that’s becoming increasingly diverse – some projections have the country becoming majority minority by 2060 – could elect one of the most openly xenophobic candidates in recent history.

As a psychologist who studies social attitudes and biases, I am interested in the impact that increasing diversity and social progress can have on racial attitudes.
