Plausible. I've never had it happen that bad (Japan's UA may be a factor there), but I do get a lot of great scientists in the late game playing Epic speed. It doesn't help that there seem to be a number of wonders which grant them in the last two eras, but as I say it hasn't so much been an issue in my games. Personally I think I'm happier not knowing. Each to their own I guess. I don't tend to play Order.
