My friends are having a debate about whether the rhythm method will work as birth control for Romy.

Romy is having a whole bunch of sex with a relatively new boyfriend. She already got pregnant (and aborted) once due to misreading an ovulation test strip. She feels confident that she won't get pregnant again by using the rhythm method. She's not on birth control and they don't use condoms.

Aaron is suspicious and thinks she's seriously risking another pregnancy. They're debating so I told them I'm making a prediction market.

If Romy intentionally gets pregnant, this will resolve to no (but she reports definitely not wanting to have a baby before February)

Crazy to be betting against both Aella and Romy on this

@AriZerner I guess the question is whether you think that these yes buys represent something other than true beliefs (eg emotional hedges) in more than 3% of worlds

@AndrewG if they were just hedges, why wait for months and then buy up to 99%?

opened a Ṁ10,000 YES at 90% order

@AndrewG 10k YES order at 90% for an hour if you wanna buy more (I don't have insider info)

@Bayesian I think I'm cooked

bought Ṁ50 YES

Who is Lexer? 5000 on no, what does he know?

bought Ṁ250 YES

🤔

@Kire_ Maybe she's feeling sick

@Kire_ oof

@Romy I highly recommend you read this for future reference
You Probably Don’t Understand Contraceptive Pregnancy Rates | by Aaron Hamlin | Medium

tldr: you gotta layer multiple methods with absolutely perfect use to not have a really high chance of pregnancy

I’ve been using the rhythm method for years, never been pregnant as far as I know.

What do you call couples who use the rhythm method?

@JohnLynch Parents

You should advise her not to abort if this happens.

You shouldn't.

@EnopoletusHarding You shouldn't be allowed to abort if you're not even trying to stop it.

@Riley12 you're free to practice this principle on yourself

Type of person who's okay with abortion but not condoms.

bought Ṁ50 YES

How is she using the rhythm method? Are they not having sex during the fertile period altogether?

I wonder how much the results are skewed by desired pregnancy resolving NO instead NA

@Enlil I second that this market would be better resolving NA than NO in case of purposeful pregnancy

bought Ṁ150 NO

@mongo too late, this was clear in description and is what people have traded on. Price it in 😘 And/or create a second market with those conditions.

bought Ṁ75 YES
