      There's been a lot of controversy about drug sniffing dogs. Here's why they are totally useless as an intervention (thread)

      Good thread. The maths of screening tests is a really useful piece of public policy knowledge that no-one knows. (See also airport security...)

      Thanks! I got my terminology a bit mixed up, but it is a really important thing. I think sniffer dogs are different to airports tho, if only because the consequences can be far more dire

          That's true. It's why it's never pure maths, but the values we attach to outcomes too. Very rare, but seriously bad outcome!

          And it's also important to remember that the rarity of the outcome is vital! If you're testing for something ubiquitous, your test can be bad. If it's only 1 in 10 or 1 in 100, your test has to be MUCH better

          The comparison with airports highlights a different factor: a claim of deterrence. This seems very relevant to air travel, and is claimed re drug policy, but drug policies are more likely out of step with expectations of communities affected.
