When it comes to Beatles references, scientists can't let it be

Budel et al.’s study is much broader in scope than these prior studies. It is not limited to a single scientific discipline like biomedical science. And they used a large language model to comb through Scopus and Google Scholar looking for references to Beatles songs—not just exact title matches but also references to specific lyrics and clever wordplays on titles and lyrics.

A little help from their friends

Once again, “The Long and Winding Road” came out on top with 798 references—substantially more than the 561 references to the Clash’s “Should I Stay or Should I Go?” In fact, the authors contend that The Beatles are the most frequently referenced musical artist in the titles of scientific papers, based on their analysis of the top 10 hits of several bestselling artists, including Michael Jackson and Elvis Presley.

Budel et al. note that Paul McCartney has said that his song is “all about the unattainable; the door you never quite reach,” which they believe makes it a particularly apt metaphor for the scientific process, “which often progresses through trial and error toward meaningful, albeit temporary, results,” they wrote. “Likewise, many of the phenomena studied in science are characterized by prolonged and unpredictable development.”

Overall, the authors found 2,048 exact matches with Beatles song titles in Scopus—over 3,000 if you add in clever wordplay—but the distribution was highly skewed. In fact, it follows a power law distribution, also known as Zipf’s law. “As network scientists we’re used to seeing power laws in earthquakes, in social networks, in wealth,” said co-author Robert E. Kooij, also of Delft University of Technology. “It turns out references to Beatles songs follow one too: a handful of songs are cited constantly and the bulk of them are used once or twice. The Beatles apparently obey the same statistics as the rest of nature.”
