More from Twitter

So regarding to my "bombshell"...it's perhaps a bit less dramatic than many presumed, yet it still troubles me a lot, to the point that I wondered whether I should stop posting on certain things


You see, I realized in the last few months that, by translating information and news related to one of the fastest growing spaceflight powers of the world...I inadvertently became a spreader of PRC propaganda.

And with me exactly 180 degrees away from them, I feel scared.

It actually started a few years ago - it's not hard to meet Chinese Twitter users interested in spaceflight, either those living overseas or find a way to climb over the wall. Not surprisingly, many of these S/F enthusiasts are interested in their own military too.

This steadily grew with my followers' count until the flagship Chinese spaceflight missions of 2020 (Chang'e 5 especially but also many others) brought in dozens of them liking/re-tweeting my info tweets sometimes, and similar no. of such followers every month.

I do casually check these new followers/users sometimes. To my horror, far too many of them routinely insults, attacks, mocks others who they see as "anti-China" or spread potential mis-information, even blatant attacks, that started off w/ their state media/spokesperson.

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.

3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
