I think your sample size might have lead you astray here. My personal experience is exactly the opposite. That said, I looked for studies of meat vs. faux meat taste and didn't find anything.

Well, as a meat-eater I've got to admit that meat substitutes have come a long way in the last few years. A couple days ago I ended up eating vegan burgers which would have passed muster as mediocre cow, and vegetarian sausage tends to be fairly acceptable as well. I can't say the same for anything made from chunks too big to stir-fry, though, and I've never eaten any vegetarian products passing as rare meat, which I tend to prefer.
