- A very common knee surgery ($14 billion per year spent on it in America) turns out to be no better than sham surgery in many cases. Plainly this supports critics of medicine who say there is overtreatment. To be fair there is good news: 1. At least this particular operation wasn’t contraindicated by high school biology. 2. The study was done and published. 3. And publicized widely enough to influence practice.
- Heart guidelines based on fake research probably killed tens of thousands of people. Making useless knee surgery look good.
- “The time you’re taking to help this girl, you could be …” A great talk by Jessica Alexander about ten years working for NGOs. Her book is Chasing Chaos: My Decade In and Out of Humanitarian Aid.
- On EconTalk, Judith Curry, the climatologist, makes the excellent point that it is weird to call someone who believes climate questions are more complex than portrayed a “denier”. In every other use of the term, a denier is someone who avoids recognizing complexity, i.e., the opposite. On the other side of the ledger, Curry makes an elementary physics mistake when she says that as an ice cube floating in your drink melts, the water level of your drink rises. (It stays the same.)
