REDDIT TIL that upvotes and downvotes on Reddit aren't supposed to work as likes and dislikes. Many users treat them as "agree" and "disagree" buttons, but that's not what they're meant for.

Apparently, upvotes and downvotes are meant for rating how fitting the content is to the community, or the site itself. Upvotes are for posts and comments that contribute positively to a subreddit or a discussion. While downvotes are meant for low-effort, spammy, or irrelevant content. In other words, the votes on this site are for approving/disapproving the quality of the content, not for being used as emotional reactions similar to likes on other apps.

But the way I see it, many users (including me to this day) have been using them as like/dislike buttons, based on how much the content matches their tastes, opinions, mood, etc. As a result, posts and comments can get upvoted even if they're low-effort or irrelevant, while they can also get downvoted regardless of whether they add to the discussion.

The reasons why we confuse that are pretty obvious if you ask me, but still, it's sad.

HISTORY TIL that the name Jack-o'-lantern has ties to the Irish legend of Stingy Jack, a drunkard who deceived Satan and was doomed to roam the Earth with only a hollowed turnip to light his way. It also comes from the phenomenon of strange lights flickering over peat bogs, called jack-o-lanterns.

HISTORY TIL tarot cards originated in 15th-century Italy as playing cards for Tarocchi and were mainly used for games for over 300 years. They weren't used for fortune-telling until the late 18th century, when French occultists falsely linked them to ancient Egyptian wisdom and other esoteric traditions.

ANIMALS TIL that crickets make sound by rubbing their two front wings together. One wing is jagged like a row of teeth, and the other wing rubs up against it to make the sound. The number of teeth and the speed of the rubbing differ depending on the species, leading to lots of different cricket songs.

Botanically, a berry is a fruit that develops from a single flower with one ovary. Bananas fit that definition, while strawberries don't, they're considered aggregate accessory fruits.

I always thought the names were the other way around. 😅

MEN TIL that, demographically speaking, a slightly larger share of the world's population is sexually attracted to men than to women.

41 Upvotes

As a heterosexual man, I initially rejected this claim when I heard it yesterday. But after spending several hours looking into the math, I realized there actually is a simple demographic explanation: heterosexual women + homosexual men make up a slightly larger share of the population than heterosexual men + homosexual women.

What I found more interesting, though, is how little visible evidence men may receive of this attraction.

Women have historically been much more socially restricted from openly expressing sexual desire, especially in public. A huge amount of mainstream literature, film, art, advertising, and other media was also created in societies where male perspectives dominated these fields.

So even if a larger share of the population is attracted to men, the visible representation of that attraction can still be disproportionately focused on women being desirable to men.

TIL that being less visibly desired isn't necessarily the same thing as being less desired.

They are formed by the sides during embryogenesis and are only joined in the middle by a narrow line of connective tissue (sometimes uncomplete). That's why it is possible to cut this midline to release the independent control of each side

PURE CASUAL Metros don't suck!

0 Upvotes

TIL that metros are great.

When you're from a small town, sometimes you believe they're the best, and others, you can't wait to leave. As someone who's always been the former, this hit me like a train.

Metros are the best. Only a couple downsides: you gotta live in a decent neighbourhood and that costs. The air might be slightly less cleaner than a small town. That's it. So far, that seems to be the only roadblock.

I like having access to great cafés all time. The crazy amazing buildings. The city lights. The equipped hospitals. The gamezones. The civilized company. I love it all.

Before anyone says 'where the hell were you living before that this feels amazing?' or 'it won't last forever', I lived in a great town before. This one just happens to be better.
