Do you tend to notice patterns of people with the same name, for instance: sharing the same characteristics? Have you had dealings (good or bad) that pursuade your decision, thus creating a bias toward people with that same name?
E.g.
Andreas are stuck-up, Kimberlys are bitches, James are flamboyant, Stephens are career-driven, Heathers have nice eyes.
