My brain hurts
"Apparently dressing well improves the holistic ambiance of a brain struggling with esoteric things like coding"
As soon as anyone mentions the word "holistic" you know that what is about to follow is nothing more than ideological diahhorea.
If you want people to code good, leave them alone and just let them get on with their "esotericisms"..
These situations are usually more about the requirement to change a shitty management team than anything else.. ( Peter Principle anyone)
