(bushy trees, of which there are very many compared with linear ones, would be an instance of Gwern's model* of confounds being [much] more common than causality?) * https://news.ycombinator.com/item?id=41291636 https://news.ycombinator.com/item?id=41291636
- Vecr 2y agoRight, but your memory functions as a collider, if there are literally no colliders anywhere you by definition won't be able to remember anything.
