Either 35, 36, or 39 Percent of Psychology Results Can’t Be Replicated

The Washington Post informs me today that in a new study, only 39 out of 100 published psychology studies could be replicated:

I wonder if I can replicate that headline? Let’s try the New York Times:

Huh. They say 35 out of 100. What’s going on? Maybe Science News can tell me:

Now it’s 35 out of 97. So what is the answer?

Based on the study itself, it appears that Science News has it right. It’s 35 out of 97. Using a different measure of replication, however, the answer is that 39 percent of the studies could be replicated, which might explain the Post’s 39 out of 100. And it turns out that the study actually looked at 100 results, but only 97 of them had positive findings in the first place and were therefore worth trying to replicate. But if, for some reason, you decided that all 100 original studies should be counted, you’d get the Times’ 35 out of 100.

So there you go. Depending on who you read, it’s either 35, 36, or 39 percent. Welcome to the business of science reporting.

THE FACTS SPEAK FOR THEMSELVES.

At least we hope they will, because that’s our approach to raising the $350,000 in online donations we need right now—during our high-stakes December fundraising push.

It’s the most important month of the year for our fundraising, with upward of 15 percent of our annual online total coming in during the final week—and there’s a lot to say about why Mother Jones’ journalism, and thus hitting that big number, matters tremendously right now.

But you told us fundraising is annoying—with the gimmicks, overwrought tone, manipulative language, and sheer volume of urgent URGENT URGENT!!! content we’re all bombarded with. It sure can be.

So we’re going to try making this as un-annoying as possible. In “Let the Facts Speak for Themselves” we give it our best shot, answering three questions that most any fundraising should try to speak to: Why us, why now, why does it matter?

The upshot? Mother Jones does journalism you don’t find elsewhere: in-depth, time-intensive, ahead-of-the-curve reporting on underreported beats. We operate on razor-thin margins in an unfathomably hard news business, and can’t afford to come up short on these online goals. And given everything, reporting like ours is vital right now.

If you can afford to part with a few bucks, please support the reporting you get from Mother Jones with a much-needed year-end donation. And please do it now, while you’re thinking about it—with fewer people paying attention to the news like you are, we need everyone with us to get there.
