If that were true, you wouldn't have to adjust the EV when taking pictures of 80% snow, because the photos at average exposure would still look exactly the same as our eyes expect it to. But our eyes are not cameras. When I'm outside and I look at a snowy landscape, I see bright white, more bright white, and some grey. If my eyes were averaging to 18% grey, I would just see a big grey landscape. Now, as someone living through my 30th prairie snow-filled winter, I can assure you: there's a lot of white looking stuff out there, it's not 18% grey...

I concede that I could have been more precise indeed. Saying that your eyes always see everything as 18% grey is indeed too lackluster, and not every scene will become grey. It should be: "When looking at an average scene with many different colors and brightness levels, the eye will see that scene as average (18%) grey." This is the reason why a Kindle looks brighter in a dark case, and why it looks green in a pink case; the eye will try to average everything out. It sometimes can't do that, with the snow landscape being a good example.
