Friendship and Shared Interests
How do our personality traits influence our relationships? Psychologists investigated this by distributing an online questionnaire to members of a local community. Participants completed self-report scales rating various aspects of friendship.
Some of the data from the first twenty self-identified Introverts and first twenty self-identified Extroverts to respond are presented in the table below.
