Lies & Damn Lies: Probability in the News

Lies? Misleading numbers? Just plain old incompetence?

Journalists are a constant source of confusion and misleading 'information' when it comes to numbers: particularly probabilities. Here, I'll break down some of what's being said in the news so we can understand what's real, what's not, and what's just not yet fully understood.

  • Death vs. case rates and perceived danger

  • The effect of uncertainty on public policy

  • Future pandemics: what is the optimal response?

  • Vaccine hesitancy: government vs. individual goals
