Now imagine someone running a real-world user study to see if it actually
works in practice rather than just in theory.  Given all the studies that 
have been done on this sort of thing in the past showing that it's not very
effective in practice, I would assume by simple extrapolation that the
answer remains "no", but I'm happy to be proven wrong.
