**Narcissism and Affective Polarization**
“_We argue that the personality trait of narcissism (entitled self-importance) is an important correlate of affective polarization. We test this claim in Britain using nationally representative survey data, examining both long-standing party identities and new Brexit identities. Our findings reveal that narcissism, and particularly the ‘rivalry’ aspect of narcissism, is associated with both positive and negative partisanship._”
