One famous example of a popular but dubious commercial personality test is the Myers–Briggs Type Indicator. “Until we test them scientifically we can’t tell the difference between that and pseudoscience like astrology.” “You should be skeptical,” says Simine Vazire, a personality researcher at the University of California, Davis. The trouble is, if you ask the experts, most of these might not be worth the money. Other questionnaires, developed and sold as tools to help people hire the right candidate or find love, take themselves more seriously.
Some are silly-like the internet quiz that tells everyone who takes it that they are procrastinators at the core. If you’re looking for insight into the true you, there’s a buffet of personality questionnaires available.
