MODERATORS
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.

Pressing the crosswalk button over and over will make the light change faster.
Apparently some are wholly disconnected, but not all, leading to some pedestrians just standing there through multiple traffic cycles because they read a cracked article in 2010 that said the buttom doesn't do anything. Pressing a second time definitely doesn't do anything but provide stress relief though.
Related is elevator close-door buttons. I hold them down for a long time which seems to work well, but for some elevators it doesn't.
Well it finally changed the 8th time I pressed it, so checkmate.
I think we know it doesn't help, but we do it anyway.
Serious question, why? Stress relief of button-pushing? Thinking it might work and that it can't be slower than doing nothing?
I just don't feel any urge to push the button.

"Bigger is better"
The harder it is to pull a bow, the faster the arrows.
Isn't that true, all other things being equal?
Depends.
Compound bows are designed such that you put in a LOT of energy where your mechanical advantage is high (at the start of the draw) then less as your mechanical advantage diminishes (at the end of the draw).
This makes the bow very "light" to pull and easy to hold drawn, but the energy with which the arrow will be fired is higher than almost any other design, save some cross-bows.
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?
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.
In a traditional long bow yes. In a modern compound bow, not necessarily.
