Is Infidelity Unavoidable? | Personality and Risk Factors

This video attempts to answer question: Can I describe infidelity in terms of personality theory and give advice on how it can be prevented? Infidelity is when somebody violates the expectations of a romantic relationship. Infidelity is the leading cause the relationship termination and is widespread. We know that about 50% of men and 35% of women will have at least one affair at some point in their lifetime.
To understand personality here, I'll be using the five-factor model remembered through the acronym OCEAN: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. Someone who would be more at risk to have an affair would tend to be high in openness to experience (intellectually curious, appreciate the arts, have a lot of imagination), low in conscientiousness (not very well organized and maybe, impulsive in terms of making decisions) high in extraversion (a lot of positive emotions, friendly, outgoing, assertive in social situations), low in agreeableness (uncooperative, tending not to trust other people), and high in neuroticism (tending to be angry, depressed, anxious, and feeling vulnerable)
