Is undetected original research a big problem in practice?
It is in biographies, for sure.
Is this policy going to have any effect on undetected original research?
Yes. It gives unambiguous grounds for removing things which cannot be verified from reliable secondary sources (Wikipedia is not a publisher of first instance) and makes it less easy for people to use Wikipedia as a soapbox. It ends sterile edit wars over the insertion of personal opinion.
I don't see why it's a problem, myself. It's not as if it's a new thing. Sure most things don't actually cite a source, but most of them *could* cite a source if necessary. It's the ones that can't which are a problem. Guy (JzG)
