Most New Psychology Findings Can’t Be Replicated. So Now What?
A massive, groundbreaking study has found that the majority of new psychology findings in the top three flagship journals can't be replicated. Where do we go from here?
The field of psychology has been shaken by a massive replication effort, which has found that out of 98 papers published in the top three psychology journals only 39 could be replicated.
From much of the coverage you’d be forgiven for thinking that this means we should discard psychology as a field. I certainly don’t believe this is the case for the simple reason that well-studied areas of psychology are full of findings that have been repeatedly tested in various different ways. Instead of resorting to cynicism, we should take this opportunity to embrace a culture of skepticism and fundamentally change the way we interpret new research findings.
Whenever you hear the words “new study,” alarm bells should ring. It isn’t new studies that you should base your opinions on; it is old studies that have been replicated again and again, and the results reported in meta-analyses and systematic reviews.
... taking a scientifically informed view of the world requires a great deal more than looking at any one study.
In that last sentence I was careful not to restrict that claim to psychology, for the simple reason that we have every indication to believe that new research is similarly difficult to replicate across many areas of science. For example, 30 percent of the most widely cited randomized controlled trials in the world’s highest-quality medical journals have later been found to be wrong or exaggerated and that number rises to five out of six for non-randomized trials — a number that is in fact worse than the rate found by the psychology reproducibility project.
So what does this mean to you, the reader, who is simply trying to distinguish fact from fiction? Obviously, it is the responsibility of researchers to make their research considerably more reliable, but this may take a very long time, and may never happen.
The solution is to take a skeptical approach to the world around us, to treat every new claim not as a problem solved, but as an open question. Questions that are best answered by looking with a critical eye at all the evidence we have. In a perfect world, I’d wholly agree with psychologist Steven Pinker that much of this responsibility lies with science journalists:
I've long argued that sci journalists should stop reporting single newsworthy studies = recipe for error. Only meta-analyses, lit reviews.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.
As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
- Master Execution: How to Get from Point A to Point B in 7 Steps, with Rob Roy, Retired Navy SEALUsing the principles of SEAL training to forge better bosses, former Navy SEAL and founder of the Leadership Under Fire series Rob Roy, a self-described "Hammer", makes people's lives miserable in the hopes of teaching them how to be a tougher—and better—manager. "We offer something that you are not going to get from reading a book," says Roy. "Real leaders inspire, guide and give hope."Anybody can make a decision when everything is in their favor, but what happens in turbulent times? Roy teaches leaders, through intense experiences, that they can walk into any situation and come out ahead. In this lesson, he outlines seven SEAL-tested steps for executing any plan—even under extreme conditions or crisis situations.
