This Musical Preference Is A Sign Of High IQ

This Musical Preference Is A Sign Of High IQ post image

The type of music that signals a high IQ.

People who like instrumental music tend to have higher IQs, research finds.

Instrumental music includes everything that does not have lyrics, such as ambient, classical, smooth jazz, big band and some film soundtracks.

Almost everyone, whatever their IQ, though, likes vocal music.

A preference for vocal music does not provide a signal about intelligence.

The reason that higher IQ is linked to the preference for instrumental music has nothing to do with the cognitive complexity of the music.

Opera, for example, is often seen as complex, but it says nothing about people’s intelligence.

The study’s authors write:

“It would be difficult to make the case that big-band music is more cognitively complex than classical music.

On the other extreme, as suspected, preference for rap music is significantly negatively correlated with intelligence.

However, preference for gospel music is even more strongly negatively correlated with it.

It would be difficult to make the case that gospel is less cognitively complex than rap.”

The conclusions come from two surveys of thousands of people who were asked about their musical preferences and given IQ tests.

Both found a link between higher intelligence and preference for instrumental music.

The results showed that…

“…net of age, race, sex, education, family income, religion, current and past marital status and number of children, more intelligent Americans are more likely to prefer instrumental music such as big band, classical and easy listening than less-intelligent Americans.”

An evolutionary explanation

The explanation for this link between IQ and musical preferences may go back into our evolutionary past.

Dr Satoshi Kanazawa, the study’s co-author, thinks that instrumental musical is more ‘evolutionary novel’ and therefore linked to a higher IQ.

This explanation is highly debatable (see Dutton, 2013), but the link is still fascinating.
