  on: What is the ev­i­dence for pro­duc­tivity benefits of weightlift­ing?

  There is some in­di­rect ev­i­dence that weightlift­ing im­proves pro­duc­tivity, as­sum­ing that cog­ni­tion is an im­por­tant de­ter­mi­nate of pro­duc­tivity.

  For ex­am­ple, a re­cent meta-study, Lift­ing cog­ni­tion: a meta-anal­y­sis of effects of re­sis­tance ex­er­cise on cog­ni­tion by Jon-Fred­er­ick Lan­dri­gan, Tyler Bell, Michael Crowe, Olivio J. Clay, Daniel Mir­man, re­ports that:

  Re­sults re­vealed pos­i­tive effects of re­sis­tance train­ing on com­pos­ite cog­ni­tive scores (SMD 0.71, 95% CI 0.30-1.12), screen­ing mea­sures of cog­ni­tive im­pair­ment (SMD 1.28, 95% CI 0.39-2.18), and ex­ec­u­tive func­tions (SMD 0.39, 95% CI 0.04-0.74), but no effect on mea­sures of work­ing mem­ory (SMD 0.151, 95% CI - 0.21 to 0.51).

  on: Which text­book would you recom­mend to learn de­ci­sion the­ory?

  An In­tro­duc­tion to De­ci­sion The­ory by Martin Peter­son is a good first in­tro­duc­tion to the fun­da­men­tal prin­ci­ples of de­ci­sion the­ory as well as the strengths and weak­nesses of causal vs ev­i­den­tial de­ci­sion the­ory (it doesn’t get into the more ex­otic the­o­ries, al­though it does con­tain a chap­ter on so­cial choice).

  It also con­tains ex­er­cises to en­sure ba­sic mas­tery of the con­cepts, but only as­sumes a back­ground of alge­bra and prob­a­bil­ity.

  in reply to: David Mears's comment on: We can all be high status

  A much ear­lier post by David Fried­man makes similar points:

  This point was origi­nally made clear to me when I was an un­der­grad­u­ate at Har­vard and re­al­ized that Har­vard had, in at least one in­ter­est­ing way, the perfect so­cial sys­tem: Every­one at the top of his own lad­der. The small minor­ity of stu­dents pas­sion­ately in­ter­ested in drama knew perfectly well that they were the most im­por­tant peo­ple at the uni­ver­sity; ev­ery­one else was there to provide them with an au­di­ence. The small minor­ity pas­sion­ately in­ter­ested in poli­tics knew that they were the most im­por­tant ones; their friends were there to be herded into meet­ings of the Young Repub­li­cans and Young Democrats in or­der to get them elected to po­si­tions in those or­ga­ni­za­tions that were the step­ping stones to fur­ther poli­ti­cal suc­cess...

  That would break the rule of “show, don’t tell” of fic­tion writ­ing, but work­ing that into the story more ex­plic­itly would help, I agree.

  in reply to: Laura B's comment on: Ad­vances in Baby Formula

  Then there’s the is­sue that sicker ba­bies of­ten have to be for­mula fed...

  Why do you be­lieve this? My son is cur­rently in the NICU (born at 25 weeks), and they push breast-feed­ing ex­tremely hard, even go­ing as far as to make it sound like neg­li­gence if you don’t at­tempt to breast­feed (due to higher in­ci­dences of NEC in pre­mies, among other rea­sons). Ba­bies whose moth­ers can’t breast­feed are sup­plied with donor milk, not for­mula. When my first son was born (who wasn’t a pre­mie or oth­er­wise sick), the nurses and doc­tors talked as if it were just a mat­ter of per­sonal prefer­ence.

  My ex­pe­rience could be un­rep­re­sen­ta­tive though, so I’d love to see some kind of jus­tifi­ca­tion for the above-quoted claim.

  The use of ‘self-con­scious’ to re­fer to hav­ing knowl­edge of your­self as a con­scious be­ing isn’t unique to LW, but is bor­rowed from philos­o­phy. Blame the philoso­phers I say!

  Any­way, they could have cho­sen to come up with a new term in­stead of us­ing the not-most widely (but still com­monly) used defi­ni­tion of ‘self-con­scious’, but that would mean even more LW-spe­cific jar­gon (which is also heav­ily crit­i­cized). It’s not at all clear to me whether push­ing to­wards greater jar­gon us­age would be an im­prove­ment in gen­eral.

  Quine cat­e­go­rized para­doxes into veridi­cal (ap­par­ently ab­surd, but ac­tu­ally true), fal­sidi­cal (seem­ingly con­tra­dic­tory, be­cause they ac­tu­ally do as­sume some­thing false or use an in­valid step some­where), and antinomy (self-con­tra­dic­tion from true premises us­ing only valid steps [ar­guably there are no such things]). I find these cat­e­gories to be helpful for im­prov­ing com­mu­ni­ca­tion about such things.

  Testable im­pli­ca­tion: com­mu­ni­ties that strongly em­pha­size up­hold­ing prop­erty con­ven­tions will con­tain more in­di­vi­d­u­als that share these in­tu­itions, while com­mu­ni­ties that do not will con­tain in­di­vi­d­u­als that share fewer.

  Don’t you agree?

  Some­thing brought up origi­nally, but never re­ally dealt with: this ar­gu­ment ap­plies a for­tiori to lob­by­ing.

  Would the defen­ders of these kinds of con­se­quen­tial­ist ar­gu­ments for vot­ing also recom­mend effec­tive al­tru­ists be­come lob­by­ists? It seems there is some ten­sion there if they don’t, or else I am (or they are) con­fused about the im­pli­ca­tions of the premises in that ar­gu­ment.
