EA’s reasons not to have kids.
"A lot of EAs chose not to have kids," said George. "It's because of the impact on their own lives. They believe that having kids takes away from their ability to have impact on the world." After all, in the time it took to raise a child to become an effective altruist, you could persuade some unknowably large number of people who were not your children to become effective altruists. "It feels selfish to have a kid. The EA argument for having a kid is that kid equals happiness and happiness equals increased productivity. If they can get there in their head, then maybe they have a kid." (2,261)
- The climate impact of one kid in the western world is huge. Maybe your biggest mitigation of climate change in your whole life will be to have less or even no kids. Climate change is threatening human life as we know it so this should be right up AE's alley, no?
- The best place for a child to grow up is in a stable loving family. If you know you won't have a long lasting stable and loving relationship, then the logical choice should be not to have kids.
- Raising kids costs money. Maybe more money than you have or could realistically miss. Also, per Peter Singer, that money is better spend on helping people from drowning (his words) or dying from a myriad of other causes (my words).
- My personal favorite: have you seen the world recently? I don't think that a world in "a late stage capitalism" or close to the "Fourth Turning", at 90 seconds to midnight, or, if you will, at the tail end of the End Times itself, is a place for toddlers to grow up in.
- Also, do these AE nerds, or many others like myself, even have a chance to ever have kids at all? We should have and hold a relationship first, no?
What was going on in SBF’s mind?
What surprised Sam, once he himself had unlimited sums of money, was how slowly rich people and corporations had adapted to their new political environment. The US government exerted massive influence on virtually everything under the sun and maybe even a few things over it. In a single four-year term, a president, working with Congress, directed roughly $15 trillion in spending. And yet in 2016, the sum total of spending by all candidates on races for the presidency and Congress came to a mere $6.5 billion. "It just seems like there isn't enough money in politics," said Sam. "People are underdoing it. The weird thing is that Warren Buffett isn't giving two billion dollars a year."

Political Disinformation and AI
Seventy-one percent of people living in democracies will vote in a national election between now and the end of next year. Among them: Argentina and Poland in October, Taiwan in January, Indonesia in February, India in April, the European Union and Mexico in June, and the US in November. Nine African democracies, including South Africa, will have elections in 2024. Australia and the UK don't have fixed dates, but elections are likely to occur in 2024.

The Slightly Complicated Theory of Obesity
In a sense, nutrition science has maneuvered itself into a corner here. Due to the religious insistence on randomized controlled trials and using a large number of people for studies, it's pretty much impossible to find any solutions unless they apply to everybody.
If we insisted on the same methods as car mechanics, we would have to declare that there is no solution for cars stranded on the side of the road.
After all, we did a large study: we took a sample of 10,000 cars stranded on the side of the road, and we attempted all popular ways of fixing them. We put gas into them, we pumped up their tires, we topped off the oil, and we checked for any engine errors.
Yet not a single one of these repairs made more than 15% of the cars run again!
Clearly, cars cannot be repaired. That's just science. Gasoline in, gasoline out!
On the importance of staring directly into the sun
Here's one of my favorite psychology studies of all time. You bring people into the lab, and you ask them, "Do you know how a toilet works?" And they say "Uhh yes, I'm not an idiot." And then you go "Okay, could you please write down, step by step, how a toilet works." And then you ask them to explain something that requires knowledge of toilets, like "How does pressing the lever on the side of the toilet cause the bowl to empty and then refill again to a certain level?"
What participants learn in this study is that, to their horror, they don't really know how a toilet works, at least not nearly as well as they thought they did. This isn't specific to toilets—you can get it with everything from spray bottles to helicopters.
