The idea that a lot of what we call laziness or stupidity can be traced back to how the brain tries to conserve energy at almost all costs.[^2] > According to the researchers, the decrease in the size of game and the need to hunt small, swift animals forced humans to display cunning and boldness—an evolutionary process that demanded increased volume of the human brain and later led to the development of language enabling the exchange of information about where prey could be found. The theory claims that all means served one end: body energy conservation.[^1] [^1]: https://phys.org/news/2021-03-human-brain-grew-result-extinction.html [^2]: [[Thinking Fast and Slow (Book)]]
