I have an op-ed on this subject in today's Wall Street Journal. The theme is that state courts are lagging well behind federal courts in excluded dubious expert testimony in civil casess. I'll post a link if and when it's available online (those with access to Factiva through their university can find it there).

I use the neologism "quackspertise" as a substitute for "junk science." Becaue the latter only applies only to science, it's a narrower concept than quackspertise, which appliess to any quackery in the guise of expertise.
