a million years of evolution

So I'm reading geof's pick and I stumble across channel decorrelation. (pp. 84, hack #26) This is a sensory technique that prefers independent data over correlated data. Its the reason why (in addition to neuron fatigue) we ignore so much sensory information because constant levels of input only provide correlation (or indicate perhaps that something is wrong much like a silent watch with no minute hand-difficult to know if it works!)
Anyway, it inspired a couple of thoughts:

1 if the brain has adapted to operate under rule 1: ignore constant sensory data because it doesn't provide independent data; then the following conundrum exists. Our macro nature tends toward constancy and predictability, (for obvious evolutionary reasons) yet brain adaptation suggests that this is not the best way for gathering information. I'm making a leap from micro to macro here but I think the statement is intuitive. If through our experiences we learn about our nature, then limiting our experiences through constancy causes an inner channel correlation, which leads nowhere. This perhaps obvious thought though lead me to a better thought:

2 an interesting program would be to take advantage of all the techniques of brain adaptation and evolution and apply them at the macro level in one's day to day life.

As I read further through the Stafford and Webb book, I will think about this and perhaps sketch out a small program.
