According to science, there's no shortage of predictors of professional success that you don't have that much control over. For instance, one study published in the journal The Leadership Quarterly found that those with strong and "trustworthy" facial structures have a professional edge. Another study, conducted by researchers at the University of Texas, found that successful men with deeper voices tend to get paid more. And according to a study published in Economic Letters, being born in June or July, which would make you among the youngest in your class, will instantly lower your chances of success.

But according to a new meta-analysis published in the journal Frontiers in Psychology, there's one really good predictor of success you do have control over, and it only requires you to answer a three questions. If you can do so correctly, it'll only mean good things for your professional future. Read on to learn what they are—and see if you can answer them yourself.

Meet the Cognitive Reflection Test (CRT)

Developed by psychologist Shane Frederick, in 2005, the Cognitive Reflection Test (CRT) is a simple, 3-item test that created to test peoples' ability to shun their brain's "gut instinct" and find the correct answer to a question. In other words, each question employs a deceptive sleight-of-hand—at first the answer may seem easy, but if you apply deeper thinking to it, you'll see that it's not quite so easy.

CRT has been used to gauge several things, such as job performance. According to the new study, researchers set out to discover whether or not the CRT was indeed a predictor of professional competence. At the end of their analysis, the researchers concluded that the test "proved to be an excellent predictor of job performance and training proficiency."

No only that, but they even recommend that some hiring managers use the test when interviewing candidates. "As the Cognitive Reflection Test correlates significantly with job performance, they could be included among the procedures used for personnel selection, particularly when cognitive intelligence tests are not included in the batteries of selection procedures," they write.

Again, the test is designed to make you think you know the answer off the top of your head. If you do that, you may have answered 10 cents, 100 minutes, and 24 days. However, those are wrong. The correct answers are 5 cents, 5 minutes, and 47 days.
