Why Science Communication Fails: How to Break Down Misleading Arguments and Inoculate Against Misinformation - The Great Simplification In this episode, Nate is joined by John Cook, a researcher who has spent nearly two decades studying science communication and the psychology of misinformation.

Had a great, in-depth conversation with @tgspodcast.bsky.social about climate misinformation (with an interesting digression at the end into my latest climate communication obsession: climate fiction).

We weren’t calling it truth sandwich when we released the Debunking Handbook in 2011, we referred to the fact-myth-fallacy structure (Lakoff is catchier than us cogsci nerds)

I talked to @johnfocook.bsky.social about dealing with climate misinformation, and he recommended learning about the common techniques that bad actors use to distort facts:

Fake experts
Logical fallacies
Impossible expectations
Cherry-picking
Conspiracy theories

Five ways Joe Rogan misleads listeners about climate changeΒ  Β» Yale Climate Connections Rogan exposes millions to climate denial. Let’s break down his tactics.

Joe Rogan has one of the world's most popular podcasts. Unfortunately, like nearly all of the most popular online shows, his tends to spread climate misinformation. For @climateconnections.bsky.social I scrutinize his recent episode with octogenarian climate contrarians Lindzen & Happer 🧡 (1/11)

It’s complementary, there’s no single magic bullet against misinformation which is a complex, interconnected problem requiring multi-pronged solutions. We need better mindsets, critical thinking and BS detection, media literacy and more

DOEresponseSite On July 29, 2025, the Department of Energy (DOE) published a report from its Climate Working Group (CWG). This report features prominently in the EPA's reconsideration of its 2009 Endangerment Finding. In response, over 85 scientists have come together to write a comprehensive review, which is

The false dichotomy of systemic and individual behaviour change Individuals aren't going to solve climate change, but they are an important part of the system that will get us there.
