Real Clear Politics (RCP) provides an average of the various polls for all the elections going on. The idea is that the average of a bunch of polls will be more accurate than any particular poll. But if most of them are biased then that will hardly produce an accurate estimate.
But they’ve just announced that they are going to use this present election (and past ones) to assign correction factors for the various pollsters going forward. In other words if the YouGov poll is always 3 points too high for the Democrat candidate then going forward RCP will apply a -3 point correction on their polls.
It’s actually a really good idea. With a really large database of historical data I could see how a statistician could develop a model that provides a much better estimate for how people will vote. I’m looking forward to this. I suspect once these pollsters start getting rated on accuracy the worst offenders will start squealing like stuck pigs. But over time it will boost the honest pollsters and who knows it might convince some of the worst offenders to mediate their lies.
