Abstract
The purpose of the current study was to explore the relationship between personality and music preferences, using the Myers Briggs Type Indicator. It was hypothesized that the sensing–intuition dimension would correlate with overall musical enjoyment. Thus, as compared with those participants who scored toward the sensing end, we expected high scorers (intuition end) to endorse more musical styles, particularly classical music, as well as to have greater musical training and involvement. This hypothesis was tested and confirmed with a sample of 104 undergraduates. Moreover, extraversion also correlated with overall musical interest, particularly for popular/rock music. Finally, thinking–feeling correlated with liking for country and western music. Whereas past research has conceptualized music preferences in terms of approach to or avoidance of stimulation, these findings support the notion of cultural involvement as a personality dimension.

Individual weights indicated that intuition predicted liking of jazz/soul/folk (0.36, P<0.001) and classical music (0.27, P<0.05). Extraverts enjoyed popular/rock music more than introverts (introversion WEIGHT=−0.34, P<0.05). Those scoring toward the feeling end of TF were more likely to endorse country-western music than those scoring toward the thinking end (=0.27, P<0.01).

... according to well-known theory, such honest disagreement is impossible. Robert Aumann (1976) first developed general results about the irrationality of “agreeing to disagree.” He showed that if two or more Bayesians would believe the same thing given the same information (i.e., have “common priors”), and if they are mutually aware of each other's opinions (i.e., have “common knowledge”), then those individuals cannot knowingly disagree. Merely knowing someone else’s opinion provides a powerful summary of everything that person knows, powerful enough to eliminate any differences of opinion due to differing information.
