    Dang!! I had never thought about it but thats crazy.

    "The chances that anyone has ever shuffled a pack of cards (fairly) in the same way twice in the history of the world, or ever will again, are infinitesimally small. The number of possible ways to order a pack of 52 cards is ’52!’ (“52 factorial”) which means multiplying 52 by 51 by 50… all the way down to 1. The number you get at the end is 8×10^67 (8 with 67 ‘0’s after it), essentially meaning that a randomly shuffled deck has never been seen before and will never be seen again. So next time you shuffle a deck, you should feel pretty special for holding something so unique! Try for yourself – if you make friends with every person on earth and each person shuffles one deck of cards each second, for the age of the Universe, there will be a one in a trillion, trillion, trillion chance of two decks matching."

    This is why I like tarot for divination.

    You never get the "same" results or answers. It always fits the current question.

    What's a religious odds argument and what has shuffling a pack of cards got to do with it?

    Usually in evolution debates odds and probability vs creationism to prove ID vs random chances.

    How often is tarot accurate? What motivates you to continue using tarot if it is inaccurate even once?

    I have a book that tries to work out the odds against various Bible prophecies having been 100% fulfilled by chance.
    Nothing to do with decks of cards but interesting.

    The chances of getting a royal flush first time is only one in 15 593 760 (I think)

    I've never had a divination session via tarot or runes ever be "inaccurate".

    I have had it where a situation didn't quite work out as I expected it after a reading (runes or tarot). Only to go back and realize I just misread the spread I had gotten. Didn't quite take an association between two cards into consideration for instance.

    Hmm. So if someone does five different spreads in one week and come up with different results each time (like it'd be crazy if they actually got the same results even once) then how is that interpreted?

    Towards the exact same question? There would be a common theme among the cards pulled. And the interpretation built from that. But that's a pretty uncommon way to use divination. It's not quite "seeing the future", as much as seeing possibilities. Or seeing something from an angle you hadn't thought of before.

    Except that evolution doesn't occur by mere random chance, thus the only "crazy loco" thing is how people are willfully ignorant and intellectually dishonest about it. This forum has had a FAQ on the subject pinned for a very long time.

    At least the scientists know how to count and don't assume everything is probabilistically independent (when it is known otherwise).

    You under-estimated a bit.

    Key word: tries.

    My guess is that the assumptions made lead to probabilities supporting their biases.

    Even the concept of '100% fulfilled by chance' is problematic.
