Interesting thought. This is the heart of my argument. "Good code is common sense" makes me wonder where is the science in deciding if code is good or not.

When deciding if code is good or not, surely there should be quantified criteria for assessment. Code cannot be judged to be "good" or "not good" without specific pre defined measures of assessment. I would suggest that close to 0% of employers that want to "see your code" are assessing against pre defined assessment criteria.
