@HpDarkman,
I was supedetermined to catch it but my alarm failed to wake me up in time ... so I missed it.

Shouldnt it be obvious that a coinflip isnt random?
Yes Hp I think it is to most of us

And thank you for the link. Now, to save us hours plowing through it I wonder if you might summarize what it says because many of us are discouraged by technical phrases like "entanglement is basicly a zero sum static " and "local superdeterministic hidden variable theory" but curious about your own reaction because otherwise why would you have brought it to our attention

And the proof is? Anyone ever managed to predict the outcome of a coinflip?

Yes Oli a quick Googling reveals the odds strongly favor one who knows all the tricks

@Olivier5,
"Trick" being collo for technique

Oli, seriously, are you suggesting that the outcome of a flip is purely random

We might have a semantic issue

@dalehileman,
Indeed, one should define "random" before proceeding. I don;t know what "purely random" means for instance. It's always a mix of chance and cause-and-effect, in my view.

All I am saying is that the idea a coin flip is not random is a rather facile cliché, which nobody is able to prove. Determinism is reassuring for our rational mind, but that doesn't make it true. For all we know, the entire universe could be totally and utterly unpredictable, including coin tosses.

Given a perfectly random flip the ratio of heads to tails would approach 1:1

Our semantic impasse must be especially acute. Techniques to favor one result over the other have been described many instances in lavish detail, as close to absolute proof as mathematically possible

I don't see how determinism comes into play here

Sorry Oli but you've lost me utterly

"...the odds tip slightly in favor of the side that faces up just before the coin is flipped."

@parados,
Thanks Par, that was the very one I was looking for

But I'm still in the dark about the coin toss re determinism

This study shows that when participants are given simple instructions about how to manipulate the toss of a coin and only a few minutes to practise this technique, more than half can significantly manipulate the outcome

Nothing to see with predicting a fair toss...

@dalehileman,
That doesn't mean the result is not random, just that the odds are not exactly 50 50.

Not entirely Oli as we haven't addressed the q of Hp' s OP

Granted that s'd'ism is lavishly covered in Google, the language is a bit beyond your Average Clod (me). Still interested in a brief rundown along with HP's reaction or comment
