The problem is that our ideas are sticky: once we produce a theory, we are not likely to change our minds.... - Nassim Nicholas Taleb

Knowledge is subtractive, not additive—what we subtract (reduction by what does not work, what not to do), not what we add (what to do).

Years ago, I noticed one thing about economics, and that is that economists didn't get anything right.

The hippocampus is the structure where memory is supposedly controlled. It is the most plastic part of the brain; it is also the part that is assumed to absorb all the damage from repeated insults like the chronic stress we experience daily from small doses of negative feelings — as opposed to the invigorating “good stress” of the tiger popping up occasionally in your living room. You can rationalize all you want; the hippocampus takes the insult of chronic stress seriously, incurring irreversible atrophy. Contrary to popular belief, these small, seemingly harmless stressors do not strengthen you; they can amputate part of your self.
