    That by not being ridiculously overtly bigoted, they have actually interrogated and rejected their own bigotry. The former is basic and mostly relies on social conditioning. The latter requires reading history and people who are criticizing things with which you may identify and therefore take very personally. The latter is not taught in school and school does not provide the tools (outside of literacy) to do so, so it’s a difficult, painful, abd regrettably rare thing to see, usually requiring sone trauma to change.

    That looking too closely at the screen will blind you or damage your eyes. This myth originated decades ago in the 1960s from an advertisement by a television manufacturer. Basically in 1967 General Electric reported that their color TVs were emitting too many x-rays due to a factory error, so health officials recommended keeping children and pretty much anyone else at a safe distance from the screen. The problem was soon resolved, but the myth endured.

    If you ask me I would say that x-ray radiation has little to do with going blind, I have no idea if radiation can actually make you blind, but it’s funny how somehow eye diseases got in the way as the only possible consequences in the myth just because we use our eyes to watch TV.

    Americans: You’re not tired after eating Thanksgiving dinner because of tryptophan in the turkey, you’re tired because you ate a lot of food.

    That cold water will boil faster than warm water.

    It’s a confusion. You should always cook with cold tap water, not hot, because hot tap water can contain excessive amounts of lead.

    There are several instances where hot water can freeze faster than lukewarm water. I believe people saw this on shows such as Bill Nye and then forgot the specifics.

      I will believe that warm water freezes faster only if I see it with my own eyes. It just goes against everything I know about thermodynamics.

        I heard hot water freeze faster when thrown in freezing cold air, because it evaporates faster - making smaller droplets and increasing the surface area

          Right, I can believe that. I was thinking of making ice cubes, which is also something I heard.

          In 2016, Burridge and Linden defined the criterion as the time to reach 0 °C (32 °F; 273 K), carried out experiments, and reviewed published work to date. They noted that the large difference originally claimed had not been replicated, and that studies showing a small effect could be influenced by variations in the positioning of thermometers: “We conclude, somewhat sadly, that there is no evidence to support meaningful observations of the Mpemba effect.”

          I’m with those guys.

    I always think about when I was taught about taste and the human tongue back in grade school, they had these diagrams about zones on the tongue corresponding to sweet, sour, bitter, etc. like a “taste map”. I’m not sure how many generations were taught about it but turns out it just isn’t true at all. So, not like it’s important but you got a lot of misinformed folks out there in regards to taste lol

      That always confused me as a child, since it was super easy to just test it for yourself. Turned out salt tasted salty regardless of where on your tongue it was, the same for the rest of the flavors.

        Yup I remember thinking to myself at the time that I must be tasting incorrectly or somehow my tongue is different from everyone else lol.

    That they’re right. You should be able to question your own opinions. A lost art, it seems
