Knowing the types of jealousy has strong implications when dealing with relationships and love. Being able to recognize the type of jealousy present in a relationship will make an individual more readily prepared to cope with it. This could potentially prevent arguments, infidelity and properly equip both partners to tend to the relationship.  If our emotions are inate, impulsive things, which we are unable to control, how then are we able to function so well in our everyday relationships?  Knowing is half the battle.  Knowing the evolutionary mechanisms behind our emtions and behaviors has many, many implications in love and other fields.  As Harris (2004) pointed out in her article, if we know that some people are prone to fits of jealous rage, then it is easier to convict them in a court of law.  If you know someone is going to be sexually jealous, then it is easier to prepare for it.
