This is the web­site of Gwern Bran­wen. I write about AI, psy­chol­ogy, & sta­tis­tics. I am best known for my writ­ings about AI scal­ing, po­etry & anime neural net­works; dark­net mar­kets and Bit­coin; blinded self-experiments; and dual n-back & spaced rep­e­ti­tion (and some­times my tomato tilapia an­chovy recipe).
