We're talking at cross-purposes here. My point is that if someone hands me a layout with wildly inconsistent internal margins, no call to action and a text column that is a full screen width wide, I can objectively say those elements are wrong and need to be fixed.
Of course, the other side to design is "style", which cannot really be quantified, merely subjectively judged against current trends, the target audience and "taste".
Apologies if I misunderstood your previous post. From your final paragraph before, I thought you were arguing that the properties you listed were not only things that could be judged objectively but also desirable principles that should be taught as part of design courses. I was countering that this would have been OK for some of the items but dubious for a few others, because while they are widely held and promoted beliefs in some quarters, they are also examples of things many designers say that aren’t backed up by rational arguments or empirical data.
