One of the great mysteries of Planet Earth is why we humans seem to mess up as much as we do and often with the best intentions trigger disasters, collapses, confusion and conflict. We are told by human experts that will all end in tears, or climatic catastrophe.
Perhaps we are not as bright as we think we are and all that brain thing what is between the ears is neither as good or as active as it should be. At least we can ask the question why.
We do not use it much seems to be implied in this article in Science Daily headed "Humans don't use as much brainpower as we like to think".
The bit I like in particular is the wonderful "using a technique known as multiple regression" in that regression to bad habits and ideas seem to be the norm of much modern thinking.
"What the data can't show is whether energetically expensive brains evolved first, and then predisposed some groups of animals to greater mental powers as a byproduct, or whether preexisting cognitive challenges favored individuals that devoted more energy to the brain, the researchers say."
I regressed therefore I am.
