Who are your favorite “hidden rationalists”?

Quick sum­mary: “Hid­den ra­tio­nal­ists” are what I call au­thors who es­pouse ra­tio­nal­ist prin­ci­ples, and prob­a­bly think of them­selves as ra­tio­nal peo­ple, but don’t always write on “tra­di­tional” Less Wrong-ish top­ics and prob­a­bly haven’t heard of Less Wrong.

I’ve no­ticed that a lot of my ra­tio­nal­ist friends seem to read the same ten blogs, and while it’s great to have a core set of fa­vorite au­thors, it’s also nice to stretch out a bit and see how ev­ery­day ra­tio­nal­ists are do­ing cool stuff in their own fields of ex­per­tise. I’ve found many peo­ple who push my ra­tio­nal­ist but­tons in fields of in­ter­est to me (jour­nal­ism, fit­ness, etc.), and I’m sure other LWers have their own peo­ple in their own fields.

So I’m set­ting up this post as a place to link to/​sum­ma­rize the work of your fa­vorite hid­den ra­tio­nal­ists. Be liberal with your sug­ges­tions!

Another way to phrase this: Who are the peo­ple/​sources who give you the same feel­ings you get when you read your fa­vorite LW posts, but who many of us prob­a­bly haven’t heard of?

Here’s my list, to kick things off:

  • Peter Sand­man, pro­fes­sional risk com­mu­ni­ca­tion con­sul­tant. Often writes alongside Jody La­nard. Spe­cialties: Effec­tive com­mu­ni­ca­tion, deal­ing with ir­ra­tional peo­ple in a kind and effi­cient way, care­fully weigh­ing risks and benefits. My fa­vorite re­cent post of his deals with em­pa­thy for Ebola vic­tims and is a ma­jor, Slate Star Codex-es­que tour de force. His “guest­book com­ments” page is bet­ter than his col­lec­tion of web ar­ti­cles, but both are quite good.

  • Doug McGuff, MD, fit­ness guru and au­thor of the ex­er­cise book with the high­est cita­tion-to-page ra­tio of any I’ve seen. His big thing is “su­per­slow train­ing”, where you perform short and ex­tremely in­tense work­outs (video here). I’ve been mov­ing in this di­rec­tion for about 18 months now, and I’ve been able to cut my work­out time ap­prox­i­mately in half with­out los­ing strength. May not work for ev­ery­one, but re­minds me of Lev­er­age Re­search’s sleep ex­per­i­ments; if it hap­pens to work for you, you gain a heck of a lot of time. I also love the way he em­pha­sizes the util­ity of strength train­ing for all ages/​gen­ders—very differ­ent from what you’d see on a lot of weightlift­ing sites.

  • Philoso­phers’ Mail. A web­site main­tained by ap­plied philoso­phers at the School of Life, which re­minds me of a hippy-dippy Euro­pean ver­sion of CFAR (in a good way). Not much sci­ence, but a lot of clever mus­ings on the ways that philos­o­phy can help us live, and some ex­cel­lent sum­maries of philoso­phers who are hard to read in the origi­nal. (Their piece on Ver­meer is a per­sonal fa­vorite, as is this es­say on Si­mon Cow­ell.) This re­cently stopped post­ing new ma­te­rial, but the School of Life now col­lects similar work through The Book of Life.

Fi­nally, I’ll men­tion some­thing many more peo­ple are prob­a­bly aware of: I Am A, where peo­ple with in­ter­est­ing lives and ex­pe­riences an­swer ques­tions about those things. Few sites are bet­ter for broad­en­ing one’s hori­zons; lots of con­cen­trated hon­esty. Plus, the chance to up­date on be­liefs you didn’t even know you had.
Once more: Who are the peo­ple/​sources who give you the same feel­ing you get when you read your fa­vorite LW posts, but who many of us prob­a­bly haven’t heard of?
