We are in the middle of a knowledge production crisis!

Science, opinion, & “goodness” are weaponized for profit, politics, & personal gain.

In my new book, I lift the curtain on the forces contributing to this chaos & look for a path forward.

Ultra-processed foods are often painted as the “bogeyman” of public health. But as University of Alberta professor @caulfieldtim.bsky.social writes, villainizing them “flattens a debate shaped by messy science and tangled policy.” thewalrus.ca/sure-ultra-proce...

86% of proposed strategies to regulate UPFs focus on changing behaviour – which can lead to equity issues – rather than addressing broader food system.

Reality:
- "Clean", "Natural", "Holistic", etc = marketing scam
- Homeopathy = science-free BS

Wellness industry is "capitalizing on fear" & spin.

"...it takes just 260 videos, which could be as quick as 35 minutes, to form a habit on the app."

"Watching 'short-form videos [tends] to lower one’s self-control, which then leads to more impulsive behaviors.'"

Washington Post reporters analyzed data from over 800 TikTok users to learn how the app turns people into power users, some of whom spend hours per day scrolling.

People trust podcasts more than social media. But is the trust warranted? theconversation.com/people-trust...

Analysis of 36,000 episodes found "nearly 70% contained at least one unverified or false claim."

"Research also shows political podcasts often rely on toxic or hostile language."
People trust podcasts more than social media. But is the trust warranted?
Just because you ‘heard it on a podcast’, it doesn’t mean the info is necessarily more trustworthy than a random social media post.

"NO evidence that giving shots separately for measles, mumps, and rubella offers any advantage in terms of safety or effectiveness."

"...these findings reveal that ressentiment is central for understanding the emotional roots of believing in conspiracy theories."

Study abstract: The ‘sour grapes’ of conspiracy theories link.springer.com/article/10.1...
The ‘sour grapes’ of conspiracy theories: how does the emotion of ressentiment predict conspiracy beliefs? - Acta Politica
This research examines how negative emotions affect the degree to which people endorse conspiracy theories. Conspiracy beliefs typically flourish in contemporary politics that evoke negative emotions. In the present article, we hypothesized that citizens in ressentiment, a particular emotional state salient in contemporary grievance politics, is a key underpinning of why people believe in conspiracy theories. Ressentiment is a multi-layered emotion, within which perceptions of unfairness, bitterness, and feelings of (suppressed) anger are central. Across three studies, we examined the role of ressentiment in predicting belief in conspiracy theories. Study 1 (United Kingdom, N = 300) and Study 2 (United States, N = 300) revealed a positive relationship between ressentiment, measured through a validated scale, and belief in conspiracy theories. This relationship was mediated by rejection of the status quo. In Study 3 (United States, N = 300, pre-registered), we used a vignette describing a fictitious country to experimentally show that evoking ressentiment (vs. control condition) significantly increased belief in conspiracy theories. Taken together, these findings reveal that ressentiment is central for understanding the emotional roots of believing in conspiracy theories.
