“Persistent beliefs which are not just demonstrably false…”

Must read here. I won’t summarize the article as you need to read the entire piece for yourself, but the implications for things I care about very deeply (such as marketing, politics, technology, religion, and education) are serious.

Take some time and read:

Sloman and Fernbach see this effect, which they call the “illusion of explanatory depth,” just about everywhere. People believe that they know way more than they actually do. What allows us to persist in this belief is other people. In the case of my toilet, someone else designed it so that I can operate it easily. This is something humans are very good at. We’ve been relying on one another’s expertise ever since we figured out how to hunt together, which was probably a key development in our evolutionary history. So well do we collaborate, Sloman and Fernbach argue, that we can hardly tell where our own understanding ends and others’ begins.

Cortical Origami

“It turns out that the huge explosion in the number of brain cells in the brain’s outer layer, called the cortex, forces that layer to swell and then collapse in on itself to form those characteristic creases. This cortical origami—which has also evolved in a handful of other brainy species, such as dolphins and some primates—may be nature’s way of solving the tight packing problem.”
