This is a great tool to explain how unaware we usually are of the environment that has so many implications for us.

But I'd like to see this go one step further: How about we measure this continuously to see whether awareness drops?

That might show that (a) humans are getting more or less aware (I guess we grow more aware since information diffusion has grown immensely) and (b) the world gets more complex and thus harder to be aware of (pretty sure on this one, see reflexive modernity)
