  • Take the test on a different day, or sleep more beforehand, or do a different test, and your IQ will change.

    Not as much as people think. We’re talking around 5 points of difference - 10 at max. Broadly speaking, the results of a well-designed test are highly consistent over a long period of time as long as it’s measured under similar conditions. It’s among the most repeatable tests in all of psychology.


  • IQ doesn’t measure intelligence

    We don’t even have agreed upon definition for intelligence so that seems like a weird claim to make.

    • The ability to acquire, understand, and use knowledge.
    • the ability to learn or understand or to deal with new or trying situations
    • the ability to apply knowledge to manipulate one’s environment or to think abstractly as measured by objective criteria (such as tests)
    • the act of understanding
    • the ability to learn, understand, and make judgments or have opinions that are based on reason
    • It can be described as the ability to perceive or infer information; and to retain it as knowledge to be applied to adaptive behaviors within an environment or context.


  • Loudness of gunshots. Every action hero would be deaf.

    Archers being told to “hold”. Nobody’s holding a +100lbs warbow.

    Sprinklers. In the vast majority of cases they react to heat - not smoke. They only go off individually rather than all at once and the water inside the pipes is black ink-like rust water sludge, not clear tap water.

    Also another plumbing related: you don’t need a huge wrench under the sink and drains are not pressurized so there’s no water spraying anywhere when you mess with the p-trap.
