People who display materialistic values tend to be seen by others as having negative personality traits like narcissism and shallowness, said Howell, who has contributed to other studies linking experiential purchases with happiness. He is also the co-founder of BeyondThePurchase.Org, which advises consumers on happiness-maximizing purchases.
In fact, according to a personality scale known as the Experiential Buying Tendency Scale (developed in part by Howell), materialistic personality types do exhibit increased neuroticism, poorer interpersonal relationships and less empathy than non-materialists. Oh, and a "Machiavellian personality profile," characterized by "envy, possessiveness, nongenerosity, and the pursuit of extrinsic rather than intrinsic goals." So there you go.
For materialists, it's a "damned if you do, damned if you don't" situation. While material purchases might make them feel happier, they can’t fully enjoy their material spoils because they feel judged. In contrast, Howell said, an experiential purchase can’t make a materialist any happier, because “they’re trying to impress others, and it doesn’t meet their psychological needs.”
