Okay lemme see if I can nerd out appropriately. this is like calculating expected value in poker right? So if I think about it that way... You’ve given me $80k. I can keep it OR I can draw a ticket. 1 ticket is worth $420k, one ticket is worth $20k, one ticket costs $80k...https://twitter.com/HLoc_Da_Gawd/status/1260586341726859266 …

To calculate expected value, I take the value of the ticket multiplied by the probability. So: 420,000 x 0.33 + 20,000 x 0.33 - 80,000 x 0.33 So that’s 138,600+6,600-26,600 =........ $118,609. That’s how much the ticket is worthpic.twitter.com/dMjnSp7VYw

Since my option is keeping $80k or taking a ticket worth $118,600, then you should “call,” or take the ticket, as it’s worth just a little more than holding onto the cash.

The tough part about this is that it’s hard to find comfort in the fact that you made the right long term financial decision if you take the ticket and it goes south lol. The best poker players in the world though DO find comfort in this. Which is so interesting.

The best poker players in the world have trained their minds to think in terms of EV. Thus they get satisfaction making a +EV play even if it doesn’t work out (pulling a losing ticket), because they know that over the long run they will make money.

If you play with the numbers of this scenario a little bit, you’ll see how the change in variables dictate a different strategy. Say I can keep $80k, or I can draw a ticket. One is for $500k, one is for $100k, one costs me $200k...(try to calculate the EV on your own)

So under these new numbers, the EV would be: 420,000 x 0.33 + 20,000 x 0.33 - 200,000 x 0.33 = 138,600 + 6,600 - 66,000 = $79,200. That’s how much a ticket is worth. Since my option is keep $80k or draw, taking the ticket would be a sliiiiiiiightly -EV play. I should “fold”.

if you wanna get really nerdy, since your EV is so close here, then in poker terms youre “indifferent.” Meaning it doesn’t matter much if you call (take the ticket) or fold (keep the money). So in this spot you should have a mixed strategy, sometimes calling sometimes folding...

Maybe depending on other factors. What’s your risk tolerance like right now? How badly do you need a sure $80k? Etc. Anyway. Shoutout to
@claytoncomic and@thinkingpoker for teaching a youngn about EV. Check out their stuff if you wanna learn more about poker it’s good shit.3 replies 0 retweets 1 likeShow this thread
One point of deliberative hygiene: it's best to assign utility values to money _before_ you do the EV calculation. Among other things it makes you less likely to overturn your result for bad reasons.

I love your point but can you walk me through what you mean by deliberative hygiene? I haven’t heard the term before lol. Is it a fun way of saying “thinking cleanly”?

Replying to @chukroxx
Yes. It's about thinking well in ways that aren't about applying an algorithm correctly or avoiding logical error; it's more about holding oneself to responsible deliberative practices (here, making self-deception and goalpost-moving much harder).
