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.

Going through the process of discovering I was trans and surrounding myself with trans people really made me re-examine how little work I’d done on issues of race, among other things. So many of the little passive aggressive things I found myself getting annoyed at cis people doing, I also found myself doing to people of color. Nothing particularly awful, but definitely inconsiderate.

In this regard I'm probably an ignorant simpleton, so what would be an example of common behavior that people think is fine but is in fact inconsiderate or offensive to others?

WiFi/Cell phones give you cancer. Both devices operated in the microwave spectrum, at or below 1 watt of power. That's about the same amount of power as the flashlight on your phone but in a wavelength so unenergetic that you can't even see it. You could put the phone in your mouth and get absorb less energy than just walking outside into the sun.

I get your point but the sun does give you cancer.

Nearly anything abouth Pre-Columbian North and South America. Turns out, there was no homogeneous "Native" culture, just as there was no "European" culture. Every different group had their own traditions and stories. They all were complex people, not one-dimensional savages or pacifists. We should simply view them as any other people.

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

[–] [email protected] 3 points 1 year ago (1 children)

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.

[–] [email protected] 4 points 1 year ago

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 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.

Good ol' desktop particle accelerators.

Mmm. I worked on CRT screens when I was in the US Navy and had some CRT monitors in the past.

After a long session, my eyeballs 100% felt 'burnt' inside.

That the average person will swallow 8 spiders a year in their in their sleep.

[–] [email protected] 1 points 1 year ago

Every one knows that its closer to 1000 spiders.

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.

You have to completely decharge batteries before recharging them.

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

β€œThe human eye can only see 30 [or 60] frames per second.” Truth is, there are some events only 1ms long that a human eye can see, so the real upper limit is [edit: at least] 1000 frames per second. There are diminishing returns, but there is plenty to be gained by getting to at least a significant fraction of that limit.

[–] [email protected] 4 points 1 year ago

The eye-brain system is totally analog. The shortest perceivable events have to do with how bright they are and how depleted the photo-receptors are in your retina. You could see a single 1/1000s pulse in a dark room but a 1kHz square wave would appear to be a continuous light.

[–] [email protected] 2 points 1 year ago (2 children)

so the real upper limit is 1000 frames per second.

This is basically the same misconception just kicked further down the road. The truth is that the human eye simply does not see in any way similarly to the way a camera sees and can't be compared. There is no upper limit.

Wait does that mean I'm just dumb?

Thinking that there are different learning styles probably helps poor teachers develop better content though.
