Can you guess which of these high-profile psychology experiments were legit?


Can you guess which social science experiments were replicated successfully and which were not - just from reading a brief description of their results?

Contemporary psychology produces a lot of surprising and fascinating findings, some of which go viral on social media and become incorporated into our conventional wisdom. However, psychology is also facing a reproducibility crisis. In many cases, striking findings published in top journals turn out to be flukes – when others attempt to recreate the experiment, using the same methodology and a larger sample size, they don't find the same effect.

How can you tell whether a snazzy new psychology discovery should be trusted? This fun quiz, created by our friends at the altruistic career services organization 80,000 Hours, can help you develop your psych-headline BS detector.

In August of 2018, the elite scientific journal Nature published a series of 21 attempts to replicate high-profile psychology experiments that had previously appeared in Nature or the similarly exclusive journal Science between 2010 and 2015. A large proportion of the findings they examined couldn't be reproduced successfully. This quiz lets you try to guess which findings were confirmed and which weren't – based on just a short description of each experiment and a few details about its methodology.

What you'll get from the quiz:

  • The option to guess which of these 21 experiments passed the replication test.

  • A full report on your performance, comparing your guesses to those of social scientists, prediction-market oddsmakers, and the general population.

  • A crash course in examining experimental methods to inform your judgment of a social science study.

  • Further research into reproducibility, prediction markets, and social interventions to chew on.
