we overestimate how much we remember, bc ➀ metamemories produce strong feelings of recognition (eg, I recall *that* I've read abt X ~indep of *what*), and ➁ survivorship bias wrt what we can even check (ie, we can't spot-check the uniform dist of what-we-used-to-remember)
new things are ~always shiny in excess of their value. the Nth time we review a memory is worth expontentially more than the (N-1)th time, bc ➀ the Forgetting Curve, and ➁ total epistemic profit (the "rent paid" by the memory) depends on its longevity
