Drowning in wellness hype, viral "experts," and five-star opinions that feel more real than facts? In this episode, law and public health scholar Timothy Caulfield exposes the certainty illusion — how "scienceploitation", predatory journals, and weaponized opinions quietly shape what we believe about our health.

Today, Therese Markow and Timothy Caulfield discuss Tim's latest book, break down the misinformation drivers that are contributing to the delegitimization of scientific expertise, and the three illusions that are being used to distort public perception. From influencers and celebrities to predatory journals and politicians, it feels like "experts" are constantly bombarding us with information, but how do we know what is true? Listen in to find out more.

Key Takeaways:

• So many of the misconceptions about health and science are now closely tethered to political ideological positions.

• Influencers are having a greater impact on beliefs around health than ever before. For example, the sale of Ivermectin spiked after a Joe Rogan conversation with Mel Gibson.

• Be aware of products and studies that are using scienceploitation and publishing in predatory journals. While they may look legitimate, they often do not have proper science behind the claim.

• Most health halos- words like "organic" or "natural" or, now, "protein" do not necessarily make the food or product healthy. But it does often convince people to buy.

"Your personal identity, your personal community has just a tremendous impact. So if you can manipulate those opinions, you can manipulate people's perceptions, their beliefs, and maybe even their actions." — Timothy Caulfield
