How Donald Trump Leverages America’s Fault Lines

In 2011 it asked the same people to rate Mr. Trump. One of the personality traits in the battery is called openness. Someone who scores high on openness is relatively more likely to be drawn to explore complicated or unfamiliar things: the person who orders that item on the menu that no one else risks trying or who is drawn to a career demanding creativity more than reliance on routine. The data show clearly that people who score high on openness have lower ratings of Mr. Trump than those who score low.

..  “Differences across global cultures and religions are too great to manage and we should stop trying so hard to minimize them” and the second is, “I try to be sensitive to people from other cultures and religions.” People who agreed with the first statement and disagreed with the second — in other words, people who didn’t think it was important to make an effort to close cultural gaps — were far more likely to hold favorable views of Mr. Trump.

.. Few people will change their minds on these things over the next several months — in either direction. Rather, these dimensions represent longstanding beliefs that are most likely developed early in life and are stable over time. This presents Mr. Trump with a rather large problem: It puts a ceiling on his support.
