Do You Get an ‘A’ in Personality?

Elizabeth Bernstein:

In the never-ending quest to help people co-exist peacefully with their spouses, children, siblings and in-laws, therapists are turning to tools used to assess the psychological stability of pilots, police officers and nuclear-power plant operators: personality tests.
I’m not talking about the pop quizzes in magazines that claim to help you determine the color of your aura or what breed you’d be if you were a dog. I am referring to tests that are scientifically designed and heavily researched, consisting of dozens if not hundreds of questions that identify specific aspects of your personality. Are you a thinker or a feeler? Intuitive or fact-oriented? Organized or spontaneous?
Answering questions like these helped Mardi and Richard Sayer get through a difficult period a few years ago when their adult daughter, Maggie Sayer, moved back into their Middletown, R.I. home.
