Summary
Overview
Freakonomics Radio explores new research revealing that traffic fatalities spike by 15% on days when major music albums are released, translating to roughly 18 extra deaths. The study, led by physician-economist Bapu Jena and his colleagues, uses natural experiments to demonstrate how smartphone distraction while driving—particularly when fans rush to stream new albums from artists like Taylor Swift and Drake—creates deadly consequences on the road.
The Research Team and Their Unusual Approach
Bapu Jena, a physician-economist at Harvard Medical School, leads a unique research group that meets three times weekly to brainstorm public health studies using natural experiments. The team includes physician-scientists like Chris Worsham, who splits his time between ICU work and data science research. Their approach involves finding clever ways to study real-world health problems using publicly available data, though many of their creative ideas fail to show significant results.
- Bapu Jena is an economist, physician, and professor at Harvard Medical School who previously made the Freakonomics MD podcast
- Chris Worsham works as a pulmonary and critical care physician at Mass General Hospital while conducting health policy research
- The research group meets three times a week with participants ranging from ninth graders to tenured professors
- Many creative research ideas don't pan out - examples include studying ADHD diagnosis during snow days and domestic violence after HBO fight nights
" Natural experiments have taken a while to take hold in medicine. Their origins are actually in epidemiology. And then economists several decades ago started popularizing their use, and they're almost certainly most widely used in economics compared to any other discipline. "
" We devote an inordinate amount of time, I think, compared to most other researchers to simply brainstorming research projects. Because there's so many data sources out there that anybody can do basically anything with data. "
The Album Release Discovery
Surgery resident Vishal Patel had the initial insight after nearly crashing his car while fumbling with Spotify to find Taylor Swift songs his wife recommended. This personal experience led him to investigate whether major album releases correlated with traffic deaths. Using federal fatality data and Spotify streaming information, he discovered a striking pattern that his colleagues initially found hard to believe but compelling enough to pursue rigorously.
- Vishal Patel is a 28-year-old surgery resident at Brigham and Women's Hospital who nearly crashed while searching for Taylor Swift songs on Spotify
- Patel analyzed the idea independently before sharing it with his colleagues because he was so curious about the potential finding
- The study examined all fatal crashes in the U.S. between 2017 and 2022, focusing on the 10 records with the most first-day Spotify streams
- Streaming volume increased by 40% on album release days, correlating with a 15% increase in traffic deaths
" We've engineered a world where the most distracting device ever made is also the one that we use to listen to music in the car. "
" I looked up, and I realized I was starting to drift out of my lane a few more seconds, and I probably would have been in a serious accident. Did you blame anyone for this near miss? Did you blame yourself, your wife, Taylor Swift? Well, I blame myself. I shouldn't have done that. I was like, I'm never going to do this again. And then a day later, I did the same thing, probably.
