Fair coins tend to land on the side they started (2023)

This is clearly the law of conservation of reality at work.

Likewise, when you hear a word for the first time suddenly you hear it five times in a row. Or if you see somebody once you suddenly start running into them all over the place.

It's because it's cheaper to repeat past realities than to create new ones.

I don't think that's true, isn't this tested in a way to obviate that psychological effect? I've done coin-flipping in computer simulations and that doesn't happen. (And yes it was a bit more realistic vs a single element, multiple linked elements flip more realistically. No air resistance simulation though.)

Oh sure, let's doubt the evidence of our senses in favor of convention. That's good science.

How good are you at Bayesian statistics, conditionalization, and understanding various biases? The simulation here should be good (it's better than mine).

Next you'll cite Bible verse.

“We toss the coin, but it is the Lord who controls its decision.” - Proverbs 16:33 (TLB)
