I wonder if instead of looking at relative size, relative energy expenditure of the brain relative to the rest of the body might be more useful.

- JetAlone 6y agoThat might assume brains all have roughly the same energy efficiency... Personally, I don't mind these heuristics too much, but we should remain focused on a teleological approach to intelligence. Size absolute or relative, energy expenditure, etc... I think the best brain is the one capable of producing the best solutions to complex problems, with the least possible disadvantages.
- erhk 6y agoWe should also consider a carbon tax on the less efficient ones
- boygobbo 6y agoI find the 'expensive tissue hypothesis' (based on brain/gut ratio) quite persuasive. See https://en.wikipedia.org/wiki/Expensive_tissue_hypothesis https://en.wikipedia.org/wiki/Expensive_tissue_hypothesis
