Some people have mastered the art of perfect gift-giving. Even those who aren’t the warmest the rest of the year can surprise others. What makes them so good at picking out the perfect present?

Associate Professor Peggy Liu has studied the psychology of gift-giving and determined that the best gifters are efficient. They’re usually well-organized and appear to have “adulting” as an art form. Liu claims that skilled gifters who enjoy giving keep note of what they gave others the previous year, if the receivers were pleased, and have a set gifting formula for individuals in their lives, such as their children’s teachers, colleagues, or neighbors. There is no formal research to identify which personality types are better at giving gifts, but Liu argues that the best gift-givers see their ability as part of who they are. Gifts are a clear way of creating social interactions and expressing that we wish to nurture our relationship with others, according to psychology professor Daniel Farrelly. “The warm and nice feeling we get from giving gifts, and receiving them, is all part of our social ways,” Farrelly says, adding that it “motivates us to engage in gift-giving.”

Imagining the joy on people’s faces when they get your gift could be the best motivation to improve. After all, it’s their happiness that encourages gift-giving in the first place.
