Isn't it unreasonable to expect that every design decision be based on logic? Human beings have two brain hemispheres. TWO WHOLE BRAIN HEMISPHERES. a right lobe and a left lobe. The right lobe is JUST AS BIG and complicated as the left lobe, in which our logic and reasoning abilities are based.

But in our culture, especially in development culture, for some reason any decision based on a process in the right hemisphere is valued far less. We call it "subjective" even though it isn't. It's the same processes that every human brain does in much the same way. This is why optical illusions can work. They work much the same way for every person, and the reasons they work are not based on logic. They're based on physical, biological processes in our visual processing systems. It's not a "logical" or "rational" process. It's a visual process.

But if a designer says that spacing is going to cause a problem, it's not valuable input because there is no "logical" reason behind it. That's not logical!

All of these statements might be true, but they neither imply nor advance one another. They are all non sequiturs. Also, there is less to the left/right brain thing than most people seem to think.

I can only guess that you just didn't read it, or don't understand it, because you're 100% wrong. Not just wrong, but ironically wrong- you're explicitly proving my point that the only thing you value is logic and reason. Which is ridiculous because our brains do a lot more than just logic and reason.

As for the left/right thing, I know that- strictly speaking, there isn't really that much of a left-right separation of concerns in the brain. It doesn't matter for my point though. It's just a metaphor for the easily demonstrable fact that brains have functions other than logic that are just as useful and important to satisfy.
