Of course, one can overgeneralize the correlations between consumption preferences and personality (character is vague and worth practically undefined) but it seems absurd to claim they are entirely uncorrelated. Take the Big Five traits: conscientiousness, agreeableness, neuroticism, openness to experience, extroversion. Each has numerous obvious implications for consumer preferences. Do you mean something else by "personality" or perhaps "growing up"?
