I Found One That Isn’t.  \nBy Maggie Ko erth-Baker  \nFiled under Science Resolutions Published Jan . 2, 2018  \n[https://fivethirtyeight.com/features/most-personality-quizzes-are-junk-science-i-found-one-that-isnt/](https://fivethirtyeight.com/features/most-personality-quizzes-are-junk-science-i-found-one-that-isnt/)  \nOur science staff is trying to lead a more scientific life in 2018. Throughout the week, we’ll be questioning whether some of our favorite habits and hobbies are based on junk science or real evidence. Here’s the first entry, on personality quizzes.  \nI f I were a witch, my Hogwarts House would be Ravenclaw. Or possibly Slytherin. It  \ndepends on what publication is directing the Harry Potter Sorting Hat’s work.  \nI am also a mild extrovert, my moral alignment is neutral, and the Star Wars character I’m most like is the Tauntaun Luke sleeps inside of in “Empire Strikes Back.”  \nAnother big part of my personality: I really like online personality quizzes. Maybe you could tell.  \nBut I’ve never really taken these tests seriously. Not even the Myers-Briggs—a test that is frequently used in professional development and hiring settings and costs $50 to take online. ($55.94 with tax. I’m an ENTP.) Call me cynical. Call me a skeptic. Call me a Ravenclaw with a dash of Slytherin. The point is, I always regarded personality quizzes as strangely addictive horse hockey, good for trading memes with friends, excellent at consuming your cash (or your employer’s—sorry, Nate), but not much more.“Astrology for nerds,” I called it. And as my colleagues and I compiled a list of the junk science we were resolved to let go ofin the new year, I fully expected to be writing about how I was going to stop taking these damn things.  \nInstead, I get to spend 2018 immersed in a new series of personality tests—ones that are actually evidence-based and scientifically sound. That’s because, while most of the personality tests shared around the internet are, indeed, bogus procrastination devices, there is a science to personality, and it’s something that researchers really can put into a quantified, testable format, said Simine Vazire, a psychology professor at the University of California, Davis.  \n The most popular—used by the vast majority of scientists who study personality—is   called the Big Five, a system that organizes personality around five broad clusters of   traits: extroversion, agreeableness, conscientiousness, neuroticism and openness to   experience.  \nYou aren’t asked about hypothetical situations. You aren’t asked about which words you like best. You aren’t given 􀇂ve images of different sunsets and asked to pick which one best reveals your inner soul.  \nThose clusters were not randomly chosen. Instead, the categories stem from research that began in the 1920s and‘30s, when researchers first theorized that you might be able to figure out the anatomy of a personality by studying the words we used to describe what people are like. But it wasn’t until the 1970s and‘80s that scientists finally had enough computing power to test their hunches. Researchers took thousands of surveys about the words people used to describe  \nthemselves and others, applied factor analysis, and came up with five big themes the traits clustered around, according to Christopher Soto, a psychology professor at Colby College. (Some researchers use a similarly derived model that adds a sixth trait: honesty-humility.)  \nThe idea behind the Big Five is that everyone’s personality has a little of all five trait groups. What the test does, essentially, is tell you where you fall on the spectrum of each of the clusters. Your results are based on comparing you to all the other humans who have taken the test. So, for instance, when I took the Big Five through a website run by Soto, I ended up in the 99th percentile for extroversion, the 58th percentile for agreeableness, the 29th percentile for conscientiousness, the 43rd per","cbCaioiBfovZV5mf","https://ap.wps.com/l/cbCaioiBfovZV5mf","pdf",1599719,"English","# Evidence vs. Junk Science\n## The Big Five trait clusters\n## Why type-based quizzes mislead\n## How questions are structured","[{\"question\":\"Why does the article say most personality quizzes are junk science?\",\"answer\":\"Many popular quizzes are treated as entertainment or produce unsupported categorization rather than scientifically grounded measurement.
