Although I always love a good quote from Black Belt Bayesian (a/k/a steven0461 a/k/a my husband)

Wow, I managed to walk into the lion's den there!

Going on to the substance, it doesn’t seem that multifoliaterose is just playing devil’s advocate here...

Yeah, I wasn't actually thinking that to be the case either. But since nobody else seems to be following your husbands advice...at least someone tries to argue against the SIAI. Good criticism can be a good thing.

...and only tread into devil’s advocacy with extreme caution...

I see, I'll take your word for it. I haven't thought about it too much. So far I thought your husbands quote is universally applicable.
