Book Review: The Secret Of Our Success | Scott Alexander 

One reason I find the claim that culture > intelligence (which I actually largely buy) particularly interesting is because I wonder what this means for AI. What exactly is "culture" (I get it for the human-specific case), and how important is it for progressing science?

The matchup between human toddlers vs. apes is surprisingly similar for memory, logic, spatial reasoning. But for social learning, the ability to learn from others rather than figuring it out on our own, we're way better. Heinrich thinks that transmitting culture from one generation to the next is the core human skill (the secret to our success), so the better the social learning, the higher the fidelity of culture transmission.

The experiment  used a tube-opening task, where the experimenter showed how the tube was to be opened.
