Wouldn’t it be nice if there were a way to categorize people so that you knew ahead of time which ones would cause nothing but heartache and which ones would love you how you need to be loved? Of course, there’s no accurate system for this kind of prediction, but the Myers-Briggs Type Indicator (MBTI) comes pretty darn close. 

Isabel Briggs Myers, along with philosophical guidance from her mother, Katherine Briggs, came up with the Myers-Briggs personality types as a way to understand what drives the extreme differences in how people interact with the world. This categorization helps millions of people gain self-understanding and make sense of differences that can cause conflict in the workplace and at home. 

But the MBTI is not only useful for self-awareness and workplace management; it can also be a strong predictor of contentment in relationships. Psychologists have conducted research to determine which personality type combinations tend to generate the highest satisfaction for couples over the long term. They also note which types have a habit of grating on each other’s nerves. Not all attractions lead to satisfaction! For example, extroverts and introverts may tend to be attracted to each other, but over the years their fundamental differences can lead to discontentment.
