While each of the MBTI preferences influences how people approach and respond to conflict, research has shown that the preferences represented by the last two letters in the four-letter MBTI type code have the greatest impact on one’s conflict style. These letters are called the conflict pairs, and they represent the combination of one’s decision-making preference for either Thinking (T) or Feeling (F) and one’s lifestyle preference for either Judging (J) or Perceiving (P).
