I'm not saying such people don't exist -- I'm saying pollsters either claimed to have adjusted the models to account for this phenomenon, or the pollsters claimed they don't exist.

There certainly were some skeptics of the polls, but these skeptics were generally marginalized or dismissed.

The point is, most media outlets who reported poll results did so with the assumption that the poll results would reflect the actual results -- NOT that the polls results needed to be adjusted.

It's clear now that Shy Trump Voters existed. Some opinion pages trafficked in arguments against their existence. I think of them in terms that our Austrian friend described. Some pollsters were better at accounting for them. I avoid "most media outlets" language and try to look at the data.

I don't think they accounted for it. These are people you can't poll

There was one small polling company who claimed they had a methodology:

instead of asking directly who someone would vote for they asked a number of other questions first to warm them up etc.

They predicted way more Trump votes - and were summarily ridiculed by mainstream pollsters I think.
