What's interesting is that the process of identifying what gets human attention is nothing new.

e.g. cartoons from the 1950s were designed to have:

- cute animals

- short and fast scene cuts

- catchy music

b/c all three of the above were known to trick the human brain into "sit still and observe" mode.

Focus groups did the same thing for advertising which then morphed into A/B testing to determine revealed preferences.

Same thing with the whole fat/salt/sugar research that led to near addictive fast food.

This is just the next logical step.
