What are some examples of 'common sense' which are nonsense?

[ryathal@sh.itjust.works]

In a traditional long bow yes. In a modern compound bow, not necessarily.

[helixdab2@lemm.ee]

So, correct me if I'm wrong, but wouldn't that also change the way that the arrow is accelerated by the bow? Like, it starts a little slower, and then has increased acceleration until the string returns the the starting position? Whereas a long or recurve bow is going to have the hardest acceleration at the very start, since that's where the most energy is stored?

And if that's true, how does that affect the flight of the arrow? I know that with stick bows, the arrow bows as it's being accelerated, and then wobbles slightly before stabilizing a few feet in front of the bow. Some of that is likely because the arrow has to bend around the bow stave. But do you see less of that with a compound bow?

[dungrad@feddit.org]

If everything is equal, the arrow gets out of tune. If you tune the arrow it becomes heavier.

Same goes for most "close door" buttons in elevators btw.

The birthday problem is super easy to understand with puzzles! For example, how does laying out the edges increase the likelihood of a random piece to fit.

[mentaledge@sopuli.xyz]

A modern compound bow will fire the arrow in a straight line, directly forwards, as the bow will have a section that allows the arrow to be shot through the space that would be occupied by the stave on a traditional bow. While the bow must obviously be gripped in line with the tension, the rest of the center section is offset to allow the archer to both shoot and sight directly along the line the arrow will travel.

How much firing then causes the arrow to bend would depend entirely on the stiffness of the arrow, but the resulting total energy being imparted is not going to be different just because the acceleration curve is different. If the arrow bends, then yes, you'd lose some energy to that.

But if anything, starting off slow and then accelerating harder as you go is the gentler and more efficient acceleration curve when accounting for that.

Some people put way too much stock in "common sense" as some blanket assumption and insult to lob at anything and everything they don't like.

They internally define what they believe to be "common" and everything that deviates is outside of that. They use it to fuel their own sense of self satisfaction and smugness, while additionally fueling negativity and hatred for others.

It fuels their toxicity and comes to define their view of everything, which is typically grossly oversimplified for their own needs.

Precisely.

That's becoming less true year over year though. Excessive debt can make it less attractive as a standard in addition to the growth of both the Euro zone and BRICS.

Don’t rely on your immune system to figure things out

... in time to keep you alive. I mean, given enough time, the body will figure things out. Vaccines are cheat-sheets to cut that time so it's accomplished before the host dies.

'Building more lanes will reduce traffic' is a classic.

• that sugary sweets make kids act "hyper"

Do you happen to have a source for that? Coz I have witnessed kids act like a horde of wild monkeys on crack right after eating dessert on multiple occasions.

Police are there to help you.

[fourpacketsofpeanuts@lemmy.world]

I listed it because it's one of the things I would sworn by too having seen it first hand. However when you conduct a double blind experiment, kids still get excited at parties / treats / days out / when their friends are over when there's no sugar in the treats.

https://www.medicalnewstoday.com/articles/medical-myths-does-sugar-make-children-hyperactive

In otherwords as parents we massively underestimate how excited or crazy kids can get just because they're excited and not because of something in their bloodstream..

[arcticprincess@lemmy.ml]

The claim and evidence here are not logically consistent.

It's like saying "cyanide won't make you dead" because, look "people still get dead from falling and crocodiles, even if there's no cyanide around".

[qjkxbmwvz@startrek.website]

I'm not mad at the huge amount I pay in taxes. I'm mad about what I get in return.

[fourpacketsofpeanuts@lemmy.world]

no, it's not. it's a meta analysis of multiple double blind studies. multiple

“For the children described as sugar-sensitive, there were no significant differences among the three diets in any of 39 behavioral and cognitive variables. For the preschool children, only 4 of the 31 measures differed significantly among the three diets, and there was no consistent pattern in the differences that were observed.”

if you did the same with cyanide you would be able to conclude that "taking cyanide and being dead is positively correlated" even if there were other causes of death. in this wide summary of multiple double blind experiements, there is no correlation between sugar intake and child behaviour. that's not to say kids don't act up and get hyper, but it's other causes, most signficiantly being parents just underestimate how hard kids find it to regulate themselves when having treats of any sort or being in a party atmosphere with friends.

I think it's just missing a bit of specificity.

Building more bike lanes will reduce traffic.
Building more bus lanes will reduce traffic.
Building more tram lines will reduce traffic.
Building more car lanes will reduce induce traffic.

Not perfect, but solid logic within reason (Building 100 more bus lanes will reduce traffic).

I'm in one of those places. In Utah, many crosswalk lights won't turn on at all unless you press the button, and the button can completely change the light timing and ordering (e.g. a protected left turn light activates at the end of a cycle instead of at the beginning).

Traffic engineers here are sometimes allowed to do some fairly interesting things.
