“People Prefer Simpler Content When There Are More Choices: A Time Series Analysis of Lyrical Complexity in Six Decades of American Popular Music”, Michael E. W. Varnum, Jaimie Krems, Colin Morris, Igor Grossmann2019-12-10 (, , )⁠:

Song lyrics are rich in meaning. In recent years, the lyrical content of popular songs has been used as an index of shifting norms, affect, and values at the cultural level. One remarkable, recently-uncovered trend is that successful pop songs have increasingly simple lyrics. Why?

We test the idea that increasing lyrical simplicity is linked to a widening array of novel song choices.

To test this Cultural Compression Hypothesis (CCH), we examined 6 decades of popular music (n = 14,661 songs).

The number of novel song choices predicted greater lyrical simplicity of successful songs. This relationship was robust, holding when controlling for critical ecological and demographic factors and also when using a variety of approaches to account for the potentially conconfoundingfluence of temporal autocorrelation.

The present data provide the first time series evidence that real-world cultural transmission may depend on the amount of novel choices in the information landscape.
