Done. $100 from you vs $1000 from me. If you lose, you donate it to her fund. If I lose, I can send you the money or do with it what you wish.

Wait, I'm not sure we're understanding each other. I thought I was putting up $100, and you'd put up $10; if she turned out to be a scam (as judged by CI), I lose the $100 to you - while if she turned out to be genuine (as judged by CI), you would lose the $10 to me.

Well I still accept, since now it's a much better deal for me!

Um, the way I'm reading this it looks like gwern is taking the position you were originally trying to take?

Yes, that's my take too... I'm not sure what mtaran is doing here - maybe he doesn't care at all about the odds or which side he's taking? I don't mind betting, but I do insist that - when it's for real sums of money like $100 - that my counterparty knows what he's agreeing to. And I'm not sure mtaran does.

For what it's worth, I too haven't understood what side you are taking. Usually people bet on outcomes which they think are more probable than their opponent thinks.

I spent way too much time thinking about the same thing. It seems to me, if mtaran believes chance of scam is lower than Gwern's, they should both agree that Gwern take the larger payout for smaller chance of being correct about it being a scam.

For what it's worth I do not think that mtaran's original bet is was that great for Gwern to begin with. A $1,000 to $100 bet implies odds of scam is at 9.1%, however Gwern stated his probability is 5%-10% putting the odds at the higher end of Gwern's estimate. If Mtaran is truly confident he needs to offer at least $1,900 to $100 payout for as this will match Gwern's lowest percentage for being a scam (5%).

Ok, I misread one of gwern's replies. My original intent was to extract money from the fact that gwern gave (from my vantage point) too high a probability of this being a scam.

Under my original version of the terms, if his P(scam) was .1:

  • he would expect to get $1000 .1 of the time
  • he would expect to lose $100 .9 of the time
  • yielding an expected value of $10

Under my original version of the terms, if his P(scam) was .05:

  • he would expect to get $1000 .05 of the time
  • he would expect to lose $100 .95 of the time
  • yielding an expected value of -$45

In the second case, he would of course not want to take that bet. I'd thus like to amend my suggested conditions to have gwern only put $52 at stake against my $1000. For any P(scam) > .05 this is a positive expected value, so I would expect it to have been satisfactory to gwern[19 August 2012 01:53:58AM].

Alright then, I accept. The wager is thus:

  • on 1 January 2013, if CI confirms that she is really dying and has or is in the process of signing up with membership & life insurance, then I will pay you $52; if they confirm the opposite, confirm nothing, or she has made no progress, you will pay me $1000.
  • In case of a dispute, another LWer can adjudicate; I nominate Eliezer, Carl Shulman, Luke, or Yvain (I haven't asked but I doubt all would decline).
  • For me, paying with Paypal is most convenient, but if it isn't for you we can arrange something else (perhaps you'd prefer I pay the $52 to a third party or charity). I can accept Paypal or Bitcoin.

This isn't fair. She probably can't get life insurance with a terminal diagnosis. She's more likely to pay for the suspension outright.

Oh right; I'm so used to cryonics funding always being life insurance I forgot it wouldn't apply here. Hm... I was trying for some sort of verification of financial commitment to being preserved. Suggestions on wording?

Comment author: philh 23 August 2012 09:43:34PM 0 points [-]

My understanding is that if CI confirms this, they're likely to set up a fund, which is what I plan to donate to.

Comment author: Alicorn 22 August 2012 07:36:52PM 0 points [-]

I'm not sure at what point during the process CI would take the suspension money, so I don't know.
