Considering the visual and structural sloppiness of the great majority of code it's a wonder the bug lists aren't a lot bigger. Most code I see is approximately illegible, with formatting gimmicks and "personal coding styles," jagged and cluttered and very easy to misread.
People still argue about early returns, for God's sake.
Management-imposed coding standards just make it worse; the code is illegible as ever but now it's uniformly illegible, since the goal of the standard is consistancy (sic) not clarity.
And the fact that developers are constantly interrupted with meetings and process means they can't concentrate well enough to think above the level of a single line.
