Unfair Coin Flip

[ErGingerbreadMandude]

I think it's somewhat impossible to be fair.

I mean, on paper you'd think a coin flip is fair, ie, 50-50 chance of either getting head or tails.

Whether you get heads or tails after you flip a coin depends on two things:

1) On which side you begin to flip the coin
2) How much force you use to flip it

I mean, I've done it before, it's not perfect but if you get a hang for how much force you're going to use and which side you begin with you can clearly see a pattern as to which side you get after the flip.

Ideally speaking if there was a machine that use this amount of force to flip a coin in this angle, I'm pretty sure enough variables are available to mathematically figure out whether you'll get heads or tails(of course discounting air resistance, winds and such) provided you know which side you begin with before the flip.

To add to that I don't think the angle in which the coin is launched affects the outcome so I guess a certain degree of fairness can be achieved by exerting different amount of force and randomly choosing which side to begin with before coin toss.

In terms of real life I think a degree of fairness can be achieved by asking someone else to flip the coin so there's inherent randomness there in that you don't exactly know which side this this person is going to decide to launch the coin and what amount of force they find comfortable in applying.
