If we consider science as a way to document reality (among other things) then "information -> decision" is an elegant point of view (if information doesn't help make decision, it is just noise). https://news.ycombinator.com/item?id=41881872

It reminds me of "brain (mostly) for movement " (no decisions to make, no brain is necessary). Sea squirts being a prime example: "As an adult, the sea squirt attaches itself to a stationary object and then digests most of its own brain." (Rodolfo R.
