“I feel your pain. I feel your pain.”

Bill Clinton was mocked by political pundits for saying that to an AIDS activist while running for president in 1992. Whether he was sincere or not, it was a public display of empathy that helped get Clinton elected.

Clinton may have been prescient about a connection between pain and politics. A large new study suggests that pain could have played a surprising role in the 2020 presidential election. Researchers found that liberals with high levels of pain sensitivity were more likely to vote for Donald Trump, while conservatives who were highly sensitive to pain were more likely to vote for Joe Biden.

Huh? I was skeptical. Initially, so was lead researcher Spike W.S. Lee, an associate professor of marketing at the University of Toronto’s Rotman School of Management.     

“We were honestly not expecting to see this kind of cross-aisle effects of pain sensitivity,” Lee said in a news release. “When we first found it, we thought it might be a fluke. That’s why we ran a replication study. We found it again. We ran extended replications and follow-up studies. We kept finding it.”

Lee and his colleagues ran seven different studies involving over 7,000 U.S. participants to see how pain sensitivity affects our moral and political views. Does it heighten them and make us hold more tightly to them? Or does the pain experience make us more sensitive and accepting of what other people believe?

Lee started thinking about that as a research topic during a dental appointment. He is very sensitive to pain, and asked that a freezing procedure be used to numb his mouth before his teeth were cleaned. Lee found himself enjoying the experience so much that he wondered what having no sensitivity to pain would do to someone’s moral compass.

His research found that liberals with higher pain sensitivity were more likely to endorse traditional conservative values such as loyalty and authority; while pain sensitive conservatives showed more support for traditional liberal values such as caring and fairness.   

The pattern continued when participants were asked about their 2020 voting intentions. As the graphic shows below, liberals (blue line) said they were more likely to vote for Trump if they had more pain sensitivity. Similarly, conservatives (red line) were less likely to vote for Trump over Biden if they were more sensitive to pain.

The pattern not only held up for how participants actually voted in the presidential election, it influenced their support for a diverse group of liberal and conservative politicians, such as Kamala Harris, Mike Pence, Mitch McConnell and Bernie Sanders.

Pain sensitivity also significantly changed the way liberals and conservatives thought about hot button issues such as immigration, global warming, unions, the free-market system and Obamacare.

Does that mean pain sensitivity makes people confused about their political views? Not necessarily. Lee says the more likely explanation is that the pain experience gives people more empathy for others and a greater willingness to look at issues from both sides.

In an age of polarized and often heated politics, that’s not a bad thing. Maybe Bill Clinton was on to something.
