  • Short answer is mostly no. Long answer is nuanced, and depends on whether you are asking about the score or intelligence

    Changing the “IQ score” (I am assuming a genuine test like WAIS-V, or at least something highly g-loaded like the old SAT):

    • You can practice for them. This is actually a bad thing: IQ test is meant as a diagnostic tool, so practice effects make IQ tests less valid. I know most neuropsychs will discourage you from practicing the exam or taking the same test within 2~5 years after taking one
    • Childhood IQ tests are somewhat less accurate than their adult counterparts, so sometimes two officially administered psych tests issued at two timepoints can differ by a lot
    • People usually score more accurately if they take the test in their native language, using norms from their country. Doesn’t affect most people, but some adult immigrants might benefit from this
    • Some people have wildly differing scores on different subsections, quite common among Autistic people I believe. This defeats the whole premise of IQ itself and you will likely never get a very accurate aggregate estimate… but that does mean your score will change based on which test you take. For example, if you are a genius at quantitative reasoning (math intuition) but below-average at say processing speed, you’ll score much higher on old SAT or AGCT (where math is 1/3, no processing speed section) versus WAIS-V (which has no math sections, but does have processing speed)

    Changing “intelligence” itself. This mostly never changes. However, if you have external factors that clog your mental, removing them do indeed improve intelligence:

    • The single best way is to have good early childhood nutrition. This obviously can’t be changed…
    • Have good nutrition and good sleep, and not take substances (alcohol, tobacco, drugs, etc…)
    • Resolve ongoing mental disorders. It is well-known that depression drops IQ by quite a bit, for example

    IQ has some white supremacist roots, so discussing about it is usually frowned upon… and even when used correctly, it is honestly much better used as a diagnostic tool. For example ADHD can get flagged on IQ tests very easily.

    Personally I think instead of trying to improve per-se, it is much better used as a tool for self-discovery especially if you have any weird neurological conditions. If you’re worried about accuracy or accidentally bombing an exam because you got too nervous with the psychologist, there are tests you can take at home such as old-SAT, CORE, CAIT, AGCT (the one US Army used to use)… which are all essentially IQ tests.


  • I got too excited about this topic and wrote too much. TL;DR: combination of in-state tuition, US/EU adopting different economics theories, and USC just being really expensive

    First of all, a lot of schools give discounts if you pay taxes. EU citizens benefit from reduced tuition at nearly all EU-universities. US also has a similar system called “in-state tuition”, but it only applies to people who study at public schools in the state where they live (a.k.a. pay taxes in). For example, UIUC (well-known for engineering, in Illinois) has an out-of-state tuition of $38,398-$46,498, but only $18,046-$23,426 for Illinois residents. Obviously this is still a lot, which leads to the main point:

    US and EU follow two very different takes on “who pays for college”. There is a major debate in economics (I think initiated by right-leaning economists) that reimbursing for university tuition is regressive, because you are paying for already well-off individuals (typically educated families send their kids to college) to further improve their earning potential. The counterargument is that university education improves the collective well-being of society and leads to positive externalities, so govts should still pay for university. This is also why nearly all countries provide free K9/K12 education, because no mainstream economists deny the positive externalities of early-life education

    But because of this ideological divergence… US universities opted for a strategy where governments mostly don’t reimburse college-level education. If the “customers” are footing the entire bill of course it would be more expensive. But it is technically a more progressive system, because underprivileged kids who defied the odds would get reimbursed by the government (such as Pell Grants) or by private foundations and can typically go to uni for almost no cost. EU in general opted for the other, more humanitarian approach, where everyone can afford to go to college, because the governments paid part of the bill.

    Personal opinion though, I don’t think the economics debate captured the full extent of what actually happened. For EU, yes the system is “more regressive” on paper, but you do end up getting more college-educated people which improves societal well-being. And the American system did indeed breed innovation! … but not necessarily in the “cheaper” direction. Some schools like Purdue University specialized into lowering tuition costs, a lot of others specialized into providing better “services” or “experiences” while massively jacking up their tuition costs because students can just do the student loan thing anyway

    Even within EU there are differences though: unless I misread it, KU Leuven (really good school in Belgium) tuition is only 1k € and under 10k € for non-EU citizens, which is half as expensive as TU Delft (Netherlands) (somewhere close to 20k € for non-EU I believe)

    And as a final note, USC is pretty expensive even by US standards. If I remember correctly, even LA folks kind of joke of it as the “rich-kids school”. A lot of the public University of California schools are much more affordable




  • Methinks this needs policy-level changes. There’s only so much we can do individually at this point

    Immediate terms: There’s nothing that can be done to curb the heatwave IMO, but there are ways to prevent danger. Namely, AC, cooling centers, public education on preventing heat-related injuries/deaths… Maybe govts can even temporarily reduce regulations/give subsidies on split-systems to help nudge some folks, but nothing much else can be done. One pet-idea I have is cooling centers, since I know Houston (which has extreme weathers) opens cooling/warming centers when the weather is too extreme; it is a very progressive implementation that benefits those who are underprivileged

    Slightly longer term: Trees/green spaces always help. Public transit systems always help. Some fairly sweeping changes in climate-related regulation (ease AC regulations, tighten car regulations, tax on pollution, etc), aimed at both reducing danger and improving the climate… or at least recuperate some “pollution tax” so the govt can use the money to plant more trees and build more trains. Also some European countries can do so much better at discouraging car use (or at least switch to EVs) given how good the train networks are; for countries without good train networks, build some

    Even longer term: Massive investments in green energy; if they are investing already, invest more. But be practical… temporary solutions like nuclear are not everyone’s cup of tea but they help with the transition. Do better on international collaboration. Find ways to discourage international trading partners from over-polluting (probably a combination of tariffs and negotiations… not my specialty).

    Obligatory not an economist/political scientist, there are probably better ways to implement these than what I suggested


  • I wonder if this has something to do with “whom you primarily identify with”? Seems to me that the primary identity comes first in naming systems

    Because there’s some interesting parallels. Even though the order is reversed, in CJ cultures (don’t know about K, presume similar) people overwhelmingly refer to each other via family names (which comes first) instead of given names. Where I grew up in China people almost never refer to your given name; most people refer to others with some honorifics + family name (brother Li, lil’ Liu, teacher Zhang, etc). In Japanese culture referring to each other via given names is reserved to close friends only. Also in these cultures the given names have a lot more diversity than in Western culture



  • Based on my records, probably averaging 40-50% on needs. Exactly 30.7% on housing, somewhere >10% on basic needs food, and maybe just a bit more for emergency. The numbers for food is a bit fuzzy since I don’t specifically separate out, say, a 6-pack beer or a really nice chocolate bar from other groceries

    For context though, I make above average salary for my area, am relatively young & healthy (so almost no healthcare needs), and didn’t mind living a bit frugal…



  • Split between either housing or bureaucracy

    Housing is… not actually about affordability, but rather the plain difficulty of even getting a rental. I’m living in supposedly a part of Europe with a good housing market, but even here every decent rental on the market would instantaneously get 20+ applicants, so it’s quite competitive… not as bad as NL, but still pretty rough

    Bureaucracy because of expat/immigrant/etc shenanigans


  • I don’t know if this is spooky, fucked up, or just really funny (in my twisted sense of humor)

    In college. I was a workaholic and didn’t sleep a lot, and I lived in a student dorm (layout was like a hotel, each student had their individual room) that was fairly well-liked by upperclassmen. Anyways there’s a random girl I know outside of class with a friend group. Generally a bright and upbeat person, quite well put-together, also an international student, etc…

    There was one night when I was just passed out on my dorm bed. And at 3am in the morning, I saw that particular girl standing in front of my dorm room with the door open. Crying, being really sad and all… Later was escorted away by the RA.

    What I still couldn’t comprehend is… First of all, why the heck was my door unlocked. Second of all, why was this random person standing in front of my door. Did she want anything from me. Also later I never heard from that girl again, what happened to her





  • Don’t think it’d be more tilting than other games with ~50% win rates. Just one example, Tekken is also ~50% win rate that is nearly completely skill dependent, but on average it involves even higher amounts of adrenaline

    Personally the games I found the most tilting are perma-deaths: Minecraft/Terraria’s hardest difficulties, Noita… Losing a 10+ hr run after making one bad decision really gets you. I think I stopped playing this type of games for that reason

    Seriously though please don’t tilt. Tilting reduces the fun of the game and makes skill improvements in skill-dependent games slower



  • Now that I’m thinking about it, I mainly have a gripe with people getting addicted to gambling. Can be in many different forms IMO; can be spending too much money at the Blackjack table (which is somewhat skill-dependent), whaling on lootboxes/gachas (where you’d literally never “win” money back), or even day trading (which is technically positive-sum)

    In theory everything is fine in moderation, but then most gambling systems reward people to whale whether they intend it or not, so…
