The surprising result of the election has lots of people questioning the validity of polls…how could they have so consistently predicted a Clinton victory? Further, if the polls were wrong, how can we trust survey research to answer business questions? Ultimately even sophisticated techniques like discrete choice conjoint or max-diff rely upon these data so this is not an insignificant question.
As someone whose firm conducts thousands and thousands of surveys annually, I thought it made sense to offer my perspective. So here are five reasons that I think the polls were “wrong” and how I think that problem could impact our work.
5 Reasons Why the Polls Went 'Wrong'
1) People Don’t Know How to Read Results
Most polls had the race in the 2-5% range and the final tally had it nearly dead even (Secretary Clinton winning the popular vote by a slight margin). At the low end, this range is within the margin of error. At the high end, it is not far outside of it. Thus, even if everything else were perfect, we would expect that the election might well have been very close.
