I've been told that it's zombie day, so I thought I'd link to this research article by Gelman and Romero:
The zombie menace has so far been studied only qualitatively or through the use of mathematical models without empirical content. We propose to use a new tool in survey research to allow zombies to be studied indirectly without risk to the interviewers.
It's on Arxiv, so you know it's real.
A fatal flaw was that they failed to have any representative posts ready to go up when the blog went live.
Had they done so, and had the content been surprisingly acceptable, the reception might have been better.
Instead we get this "Hi! Welcome to ShillBlog!" (crickets) and everyone, quite reasonably, expects the worst.
They also pack more punch - compare the ratios of group to phase velocity.
