The Polls Missed Trump. We Asked Pollsters Why

The polls missed Donald Trump’s election. Individual polls missed, at the state level and nationally (though national polls weren’t far off). So did aggregated polls. So did poll-based forecasts such as ours. And so did exit polls.

Institute for Advanced Study (IAS)

The Institute for Advanced Study (IAS) in Princeton, New Jersey, in the United States, is an independent, postdoctoral research center for theoretical research and intellectual inquiry founded in 1930 by American educator Abraham Flexner, together with philanthropists Louis Bamberger and Caroline Bamberger Fuld. The IAS is perhaps best known as the academic home of Albert Einstein, John von Neumann and Kurt Gödel, after their immigration to the United States. Although it is close to and collaborates with Princeton University, Rutgers University, and other nearby institutions, it is not part of any university or federal agency and does not charge tuition or fees.<sup>[2]
