What MBTI type is most likely to cheat?
The short answer
Across surveys, ESTPs and ENTPs appear most often in cheating data, followed by ESFPs. The shared trait: high stimulation-seeking, low impulse control, and comfort with risk. But type explains a small fraction of cheating behavior — life context, opportunity, and relationship satisfaction matter far more.
Why ESTPs and ENTPs over-index
Both types are high in Extraverted Sensing or Intuition, which seeks novelty. Both are present-focused or possibility-focused, which weakens long-term thinking. Combined with low conscientiousness in some sub-populations, the result is more impulsive decisions including in relationships. This isn't destiny — many ESTPs and ENTPs are deeply faithful.
Which types cheat least
ISFJ, ISTJ, INFJ, and INFP show up least often in cheating data. The shared trait: high values-orientation, deep commitment once chosen, and discomfort with deception. ISFJs and ISTJs especially tend to stay in unhappy marriages rather than cheat or leave.
Type doesn't excuse it
Anyone of any type can cheat. Anyone of any type can stay faithful. The 'I'm an ESTP so monogamy is hard' framing is a cope, not an explanation. Type predicts statistical tendencies; it doesn't determine individual choices.
What actually predicts cheating
Better predictors than MBTI: relationship satisfaction, opportunity (proximity to attractive others, professional travel), past cheating history (the single strongest predictor), and attachment style. If you want to predict cheating risk in your relationship, look at these, not MBTI.
