Teaching Critical Thinking as a Public Health Initiative

Tim Caulfield—a Law Professor at the University of Alberta and the author of Is Gwyneth Paltrow Wrong About Everything?—wants to help us get better at fighting misinformation about health.

This past Monday, Caulfield came to the Petrie-Flom Center’s Health Policy Workshop and spoke to an audience of Harvard Law students, affiliates from throughout Harvard University, and academics and community members from the Boston area.

During his fascinating and dynamic presentation, Caulfield covered a lot of ground. He discussed political polarization on Twitter, the profit-maximizing machinations (or self-delusion) of celebrities pedaling bunk health products, and evidence that false claims spread faster than true ones. All that may leave one feeling pessimistic and Caulfield would likely sympathize with your pessimism. Yet, the presentation also contained reasons to have hope.

Caulfield discussed the ways using narratives can make connections and fight misinformation, the power of consumers to initiate complaint-driven efforts to enforce truth in advertising law, and empirical research that suggests that the relevant critical thinking skills to help people make well-informed, rational decisions about their health can be taught.

This last point about teaching critical thinking stuck out to me.

I’ve just now spoke about “well-informed” and “rational” decisions. What counts as “well-informed” and “rational” will, of course, differ depending on one’s perspective and values. And it’s important that we keep this in mind when assessing the quality of the decision-making and discourse of a large population.

Yet even with these caveats in place, I take it that there are still some objective value claims we can make about some health-based decisions people make.

For example, getting your children vaccinated for measles, mumps, and rubella is a good decision, while purchasing a jade egg from Gwyneth Paltrow to put in your vagina is not (or at least not good for your health).

And if we can be doing things to help teach people how to make better, more-informed decisions about their health, for those of us interested in promoting health in the general population, this seems like an important avenue to pursue.

The study Caulfield cited was from a 2017 publication in which researchers found that primary school children (ages 10-12) in Uganda who were given nine 80-minute lessons in which they were taught about “12 concepts essential to assessing claims about treatment effects and making informed health choices” scored an average of 20 points higher than students who did not receive the instruction on a test meant to examine students’ ability to make informed, health-based decisions.

This is a hopeful finding.

In a society where people are already concerned about the population’s lack of critical thinking skills, evidence that such skills can be taught, and that they can be used to help people make better-informed decisions about their health, provides us with plenty of reason to fight for the teaching of critical thinking skills.

People are already calling for the teaching of critical thinking skills to counteract other societal issues, and courses like “Calling Bullshit: Data Reasoning in a Digital World” have begun cropping up online. Those of us concerned with fighting for improvements in health outcomes ought to rally behind these efforts.

If teaching critical thinking can lead to better decision-making about health, we should start treating the teaching of critical thinking as an important public health initiative.

One thought to “Teaching Critical Thinking as a Public Health Initiative”

  1. “…an average of 20 points higher…” What percentage is that?
    And yes! Critical thinking NEEDS to be a skill that is REQUIRED to be taught in all high schools! I’d be willing to pay more in taxes to fund this.
