Follow the money
These studies raise alarm bells with me.. both the pro and con sides. Who's paying for them? Andy why? Someone sitting around a college campus or research site just doesn't jump up and say "I think I'll research and do a paper on X!". So El Reg didn't do or was unable to do a "money" check on who is paying for what. To me, that's the sad part. Without those bits of data, this is just so much headline grabbing and some smoke and mirrors.
