“Prop. 45 would decrease the cost of building a new home by $75,000 on average” wsj.com/opinion/prop-4…
Overwhelming opinion that duty sex on ave has more total gains than losses.
@PirateWires "why are so many rationalists convinced AI will kill everyone while also participating in practices like 'consensual non-consent' orgies". Its really just our/their unusual taste for abstraction.
@lefineder That really is quite good.
What will end up being the biggest tech:
“These views are rooted in a once-fringe Silicon Valley ideology called 'transhumanism.' Transhumanists believe that technology will allow us to transcend humanity either by creating a new species or by combining ourselves with machines. Why go beyond humans? Because these new “posthumans” will be smarter than us. They will be infallible. They will go to the stars and conquer the universe. They will live forever." Them's my peeps. theatlantic.com/ideas/2026/10/…
@Polymarket I'm not seeing so many practical applications here.
"even though people can apply to jobs [in the same firm], most workers are terrified of applying because they're scared that [their current] manager will find out and retaliate" aeaweb.org/research/talen…
“There are no dumb questions” - oh yes, yes there are.
@Rainmaker1973 I doubt this will save her language from extinction.
I'm doing this DC event today: luma.com/groundwork_dc
@yauneyz That’s not what my poll respondents say
Duty sex is equally common for men vs women. On average, does partner who does their duty lose less than partner for whom duty is done gains? Poll in reply.
🧵"Who Engages in Duty Sex?—Infidelity Concerns and Mate Value Discrepancies" NEW paper on 'Duty Sex' in Evolutionary Psychology journal from myself, my friend @katebmetcalfe and Dr. Cindy Meston! Summary of results in thread. Link at end of thread Available open access to all!
@bryan_caplan There are different possible coalitions who might make backlash to block prediction markets. One does focus on sports betting as the bad thing.
@jessi_cata You can use this understanding to make or maintain a healthy cultural evolution process. So your morals are apt. As else all will crash n fade.
While evolution may have promoted folk morality, policy would do better to rely on expert understanding of morality, which sees it as evolved. overcomingbias.com/p/prefer-evolv…
If you want to do X, have a big $, & know of experts on X, the 1 thing elites agree on is that you must NOT directly approach those experts. Instead you MUST find elites nearest you & pay them >10% of X to do proper introductions, due diligence, etc.
@ergonoatia @CollinRugg I didn't intend an insult.
Best for traders to have a day job. Else they get too tempted to trade just to be doing something.
a former jane street trader describes a very expensive problem: doing all the research, building a strategy, then getting bored when it tells you to do nothing. “The problem was, most of the time the data told him to do nothing.” so the trader starts dabbling in other trades
