Better Marriages > Personality differences in relationships
It's been said that opposites attract, yet personality experts Barbara Barron-Tieger and Paul Tieger through their studies of hundreds of couples found that the more similar the personality types of the couples, the more satisfied they are with their communication.
However, this does not mean that you must find a soulmate with just your same type to build a satisfying relationship. In fact, the most common pairing among couples is two Myers Briggs type preferences in common, out of four total, or some similarities and some differences.
Different personality types have different ways of seeing the world. If we expect others, especially those closest to us like our significant other, to think the way we do, we're bound to be frustrated by the differences.
Myers Briggs with its four axes, makes the differences easier to discuss:
Introvert vs. Extrovert - whether you are energized by external interactions vs. internal thoughts and ideas.
Sensing vs. iNtuition - practical and realistic vs. abstract and imaginative
Thinking vs. Feeling - whether you make decisions based on facts and logic, vs. values and harmonious relationships
Judging/Percieving - whether you prefer finishing tasks and coming to decisions, vs. having options and flexibilities.
Enneagram with 9 different types are a bit more complex. You can think of it as 9 different internal drivers.
Other popular ways of looking at differences in relationships include the popular 5 love languages, or Mars/Venus. Keep in mind with the latter, some men are from Venus and some women are from Mars! In fact, A study by Bobbi Carothers and Harry Reis with over 13,000 individuals, published in The Journal of Personality and Social Psychology, finds that men and women generally do not fall into different groups. "Thus, contrary to the assertions of pop psychology titles like Men Are From Mars, Women Are From Venus, it is untrue that men and women think about their relationships in qualitatively different ways."
