It is important to know that I really - pretty much know what you are going to do. I have been watching their whole - life and am additionally an immortal being; i've been doing this a long - time and always guess correctly. It's also important to know that I am - unbiased and don't care which decision you make, I have nothing to gain - either way. - - Here are two boxes: a large and a small. The small has a 10 shekel coin - in it (show everybody). The large one may or may not have a thousand - shekels in it; you don't know. Your choice is to either take only the - large box or to take both the large and small boxes. The twist is that - I already knew which decision you will make and decided whether or not - to put the $1000 in the large box or not based on that knowledge. - If I knew you would "two box", then I left the large box empty. If I knew - you would "one box" then I filled it. - -Dominance Mindset ------------------ -Regardless of what decision was made previously, and whether or not there -is anything in the large box, the person is better off taking both boxes; -either they will get just $10 (better than none) or $1010 (better -than $1000). So two-box. - -Trusting Mindset ----------------- -The predictor is pretty much always right so we can just ignore the -possibility that they are wrong. In this case, choosing to one-box -implies that the Predictor knew you would and you get $1000; -choosing to two-box implies that the predictor knew you would and you -only get $10. - -The predictor doesn't even have to be perfectly accurate; say they are -90%: -If you one-box, your expected value is $900. -If you two-box, your expected value is $110. - -Discussion ----------- -It's disputed whether this is a paradox, and there are many deeper arguments -that I don't have time to go into here. Ultimately, I am a one-boxer -though this is something of a minority position. - -Afterword ---------- -The person who taught me this paradox, Professor Augustin Rayo, a -two-boxer, then had this to add. He was talking with his one-boxing friend -and accused her of letting irrationality undermine her logic: she is so -optimistic that if a statement S is unprovable, but it would be nicer if S -was true than false, then she pretens that S is proven. So basically, even -though there is no rationalization, she will accept a statement "just -because it would be nice", and this isn't how logic works. To which she -replied "but wouldn't it be nice if it was?". - diff --git a/misc/payments.page b/misc/payments.page deleted file mode 100644 index decf409..0000000 --- a/misc/payments.page +++ /dev/null @@ -1,20 +0,0 @@ - -Costs of various payment plaftorms ----------------------------------------- - -As of Dec, 2011. - -Visa rates go down for reliable or "small ticket" vendors; eg 1.65% + $0.04 per -swipe.
