An ego defense similar to splitting is idealization. Like the positive end of splitting, idealization involves overestimating the positive attributes of a person, object, or idea while underestimating its negative attributes. More fundamentally, it involves the projection of our needs and desires onto that person, object, or idea. A paradigm of idealization is infatuation, when love is confused with the need to love, and the idealized person’s negative attributes are glossed over or even imagined as positive. Although this can make for a rude awakening, there are few better ways of relieving our existential anxiety than by manufacturing something that is ‘perfect’ for us, be it a piece of equipment, a place, country, person, or god.
