Oversampling Is the Latest Hotness in Trumpland

Last night I went out to dinner and briefly checked in on things when I got back. While I was busy with some other stuff, I had this idle Twitter conversation:

I had been out of touch with the news for maybe six or seven hours, nothing more. And yet I was completely out of the loop on the latest campaign idiocy. I had no idea what this was about, which explains my foolishly casual tweet. This morning I found out:

This post has currently been read by 1.3 million people, and is ricocheting through the Trumposphere at light speed. Apparently oversampling is this year’s deskewing.

In case you care, oversampling is a normal and longtime practice for folks who are running presidential campaigns—which is what John Podesta was doing. If you survey, say, a thousand people, you’re likely to get a sample of only 130 African-Americans. This means that if you happen to be particularly interested in African-American voters, you need to deliberately oversample them in order to get a statistically reliable pool of respondents. The same is true for any smallish group of people. If, for some reason, you want to target Hispanic environmentalists or white women under age 30, you have to oversample them too.

Ordinary polls don’t normally do this, though they do sometimes. For example, suppose everyone is obsessed with blue-collar white men and their alleged anger at the political system. A polling firm might want to oversample them in order to report how they really feel. That wouldn’t affect the overall poll, though. It would be released as a separate survey on a matter of current interest.

Anyway, this is all obvious and simple, which explains my tweet above. But hell, what do I know? Do the yahoos peddling this stuff know it’s nonsense but only care about ginning up an army of easily-duped malcontents on November 9? Or are they genuinely ignorant? Who knows? But naturally Donald Trump is all over it:

Jesus, this election is dispiriting. I’m beginning to think the whole thing is a spectacularly successful plot by the pharma industry to boost sales of anti-anxiety drugs and prescription blood pressure meds.

HERE ARE THE FACTS:

Our fall fundraising drive is off to a rough start, and we very much need to raise $250,000 in the next couple of weeks. If you value the journalism you get from Mother Jones, please help us do it with a donation today.

As we wrote over the summer, traffic has been down at Mother Jones and a lot of sites with many people thinking news is less important now that Donald Trump is no longer president. But if you're reading this, you're not one of those people, and we're hoping we can rally support from folks like you who really get why our reporting matters right now. And that's how it's always worked: For 45 years now, a relatively small group of readers (compared to everyone we reach) who pitch in from time to time has allowed Mother Jones to do the type of journalism the moment demands and keep it free for everyone else.

Please pitch in with a donation during our fall fundraising drive if you can. We can't afford to come up short, and there's still a long way to go by November 5.
