So this study didn't even really measure whether people who were diagnosed with schizophrenia were more likely to get dogs as children It measured who was more likely to REMEMBER getting a dog as a childpic.twitter.com/9wIOr6YxN0

And using the time that they remembered having a dog as the time-point for a longitudinal analysis is...problematic For one thing, you don't have accurate pet death data. You don't actually know how long these people were exposed to pets!

The fact that the analyses were the wrong way around, the exposure was a bit meaningless, and that the stats were probably misreported is probably enough And yet, the study was published, and got into the NYT *sigh*

TL:DR - dogs don't prevent schizophrenia - schizophrenia may prevent dogs - even then, probably not - this study is a mess
