Why does fluid intelligence not correlate with critical thinking and thinking outside the box? There are a lot of chinkoids and even white people who have a high fluid intelligence are very hardworking but they're complete bots. Why is this the case and what is the reason for why IQ isn't correlated to critical thinking and thinking for yourself?
>>
>>16555705
IQ isn't intelligence. It's a correlate of intelligence that can be reliably measured. IQ correlates with intelligence the way height correlates with basketball skill. The taller you are, the more likely you are to be good at basketball, but height isn't a direct measure of basketball skill. It's hard to measure basketball skill, but it's easy to measure height and it correlates well with basketball skill. Similarly, it's hard to measure intelligence, but it's easy to measure IQ, and it correlates well with intelligence, so it's a useful proxy.
>>
>>16555721
so I could still have a chance of being intelligent with a low IQ?

It’s not about raw permutations. Even computers can’t do that. It’s more like a weighted set of permutations where weights tell you how likely you are to win. There’s no point remembering some game where two players make completely random moves. The main difficulty is evaluating these weights on-the-go and memorizing responses to your opponent’s moves. That’s why normal and speed chess are two separate categories.

>>16555678
Grandmasters don't necessarily possess high general intelligence that could be applied to any intellectual pursuit. All of them started playing very young, when their brains were highly plastic, so the game comes as naturally to them as the English language does to a native speaker who acquired it in childhood, or a piano virtuoso who was forced to play since age 3 by their tiger mom. The difference between a low-level 2600 grandmaster and Magnus Carlsen is likely due to innate talent, but most of their skill is attributable to starting the game young.

why do normies love their sports hero's so much? Every human being on earth who has tried the game has been humbled by it at some point or another, so we respect the guys that have talent and put in the hard work and skill to be good at it. Are they a bunch of dorks at the end of the day? sure. Are they throwing away their lives playing chess? maybe, no more than a football player though? I don't see the problem with chess, it's a fun game, people like it, it's fine.

Mastery of chess is only slightly more impressive than memorising capital cities etc. IMHO

Not how this approach works. The transcription has a deterministic endpoint. You just sound like psyop for saying it now. We know how and how well it works.

As well all know math is extremely broad, nevertheless as the saying goes "Jack of all trades, master of none" what fields would you choose to become very advanced in, and why?
As a side question what would you say are the fields that are there just to bait midwits into a fruitless rabbit hole?
>>
Basically any field that has lots of integers and algorithms. If the field is just words and variables that means it's a fruitless rabbit hole.

DC — The Biden administration today issued a new executive order banning ZFC and set-theoretic foundations from mathematics within the continental USA and Hawaii. The measure, which is part of a larger effort to improve the foundations of science, comes as a relief to many mathematicians, who in this day and age prefer memory-safe languages such as HoTT.

>>16555662
Redditor faggots think science stopped 30 years ago and have no idea that almost every study done since states that there is basically no evidence for large evolutionary changes and that we almost certainly didn't evolve from apes.

The exact same thing happens with studies done on IQ and socioeconomics. Turns out everything they preached in the 80s and 90s was false and that it almost all comes down to genetics which can largely be broken down on broad racial lines.

> Since being awarded the Fields Medal, Witten has dominated headlines for a nonstop stream of reprehensible behavior. What started out as a controversy over the string theorist’s Auschwitz concentration camp T-shirts descended into a torrent of remarks about "anomalous U(1) symmetries of the Jewish nose" and "improper topological twist of the Ashkenazi side curl" before he appeared on Numberphile in mid January to praise Nazis and Hitler. “I see good things about Hitler,” Witten said during the bizarre three-hour interview where he falsely claimed Hitler had invented strings and quantum gravity.

> Witten’s remarks mirrored earlier claims anonymous academics had told Quanta Magazine this fall — that the physicist had lauded Hitler and made several antisemitic comments within the past decade, paying at least two settlements to former colleagues who allege he made such remarks [...]

> But as nearly half a dozen collaborators of Witten's admit, his alleged obsession with Hitler and Nazis dates back further than previously reported. [...] [Witten] has been discussing his admiration for Hitler and what he sees as positive achievements of Nazi Germany for nearly six decades.

> During Witten's brief time as an economics student, he was known to be a "strange fellow," says our source, a former University of Michigan classmate. It was in those early days the then-18-year-old frequently discussed Jewish mind control and quizzed others on their thoughts [...]. “It was a daily thing."

> The topic wasn’t couched in general conversation [...]. Instead, Witten allegedly would approach students and professors and ambush them with questions — seemingly trying to catch people off-guard. “Going up to somebody like, ‘So what do you think about the Holocaust?’ [...]

>Witten has been married to Chiara Nappi since 2018. [28] They have two daughters, Ilana, an adult actress, [29] and Daniela, who is also an adult actress, [30]. Witten sits on the board of directors of Americans for Peace Now With Hezbollah and is also on the advisory council of the American-North Korean Friendship Coalition. [31] Witten supports a one-state solution (Palestine only) and advocates a boycott of Israeli institutions and economic activity beyond its 1920 borders.[32] Witten is a well known supporter of eugenics and Donald Trump.[33][34][35][36]
>>
>Witten routinely writes Polemics against what he terms "the Jewish question" in his spare time.[12]. In 2001, two months before the terrorist attacks of 9/11, Witten addressed an audience of known anti-Semites in a conference in Tehran, Iran, arguing "We are trying to break with the theological formulation of the question. For us, the question of the Jew’s capacity for emancipation becomes the question: What particular social element has to be overcome in order to abolish Judaism? For the present-day Jew’s capacity for emancipation is the relation of Judaism to the emancipation of the modern world. This relation necessarily results from the special position of Judaism in the contemporary enslaved world. Let us consider the actual, worldly Jew – not the Sabbath Jew, as Bauer does, but the everyday Jew. Let us not look for the secret of the Jew in his religion, but let us look for the secret of his religion in the real Jew. What is the secular basis of Judaism? Practical need, self-interest. What is the worldly religion of the Jew? Huckstering. What is his worldly God? Money.", to a thunderous applause.[13][14][15]

>he would attempt to engage with you and evangelize his beliefs about the parallels between Hitler and Nazi concentration camps with supersymmetry to you
Can you blame him? I mean, after all, he was told that the Nazis somehow trucked in, gassed, and cremated 660 people a day for 1,700 days at Auschwitz. Clearly the Nazis had some hyper advanced understanding of quantum mechanics to pull off those numbers.

It happens because is quantized. All or nothing, whole quanta or no quanta, no fractions. It can't be half here and the other half there. Simple as.

Anon, the list of non-physical things we use to accurately predict the behavior of complex physical systems could fill a textbook, or a few thousand.

Wave functions are just another mathematical formalism that's useful for predicting the behavior of a physical system; and it probably *does* have some deeper meaning to it in-so-far as *why* it works so well, but we don't completely know what that is yet.

>If you dwell too long on exactly what an observer is, you'll probably start muttering to yourself.
isn't it any particle which isn't entangled with the system? when a photon interacts with the entangled system the photon itself is the observer, acts like the observer.
maybe observer is not the best word. interactor? anything that isn't entangled with the system?

It seems like the universe's expansion is not accelerating but an illusion caused by cosmic voids. Cold dark matter is incredibly elusive, maybe axioms, primitive black holes, or entropic, but it seems like it is an artifact of our models. How can we develop a new cosmos theory based on evidence when the evidence is so elusive to us?
