Causal Models At Work

Scott Alexander shares two humorous medical anecdotes that highlight the potential for misunderstanding complex health information. Longer summary
Scott Alexander shares two humorous anecdotes involving medical professionals and patients, highlighting the potential for misunderstanding when discussing complex medical information. The first involves a conversation with an AIDS specialist about life expectancy for HIV patients, while the second features Scott as a doctor discussing medication for alcoholism with a patient. Both stories demonstrate how literal interpretations of medical advice can lead to absurd conclusions, emphasizing the importance of clear communication in healthcare. Shorter summary

[Epistemic status: loosely based on a true story]

AIDS Specialist: You know, people think AIDS is a death sentence. But how long do you think the average person lives after getting HIV?
Me: I don’t know.
AIDS Specialist: Thirty years! Isn’t that amazing? You can get HIV, and probably you’ll live another three decades!
Me: Really?
AIDS Specialist: Yeah.
Me: So, the trick is, give yourself HIV when you’re eighty, then live to be a hundred ten.
AIDS Specialist: I like you.
Me: Really?
AIDS Specialist: No.

And a few weeks later:

Me: Do you have a family history of alcoholism?
Alcoholic Patient: No. Why?
Me: Well, I am trying to figure out whether to prescribe you this medication, and studies suggest it works best in patients with a genetic predisposition to alcohol abuse.
Alcoholic Patient: I don’t understand.
Me: The medicine only works if one of your parents drinks too much.
Alcoholic Patient: Well, I think I can get my dad to start.
Me: NO!
