The eternal struggle of organic chemistry students! On the far ends of the intelligence bell curve, both the simple-minded and the geniuses agree: "You don't have to show protons leaving when drawing mechanisms." Meanwhile, the middle-IQ chemistry professor is having an absolute meltdown: "NO!! YOU MUST EXPLICITLY SHOW PROTONS LEAVING WITH ANY BASE PRESENT!!"
This is the perfect illustration of horseshoe theory but for chemical mechanisms. The truly brilliant and the blissfully clueless arrive at the same conclusion while the "well-actually" crowd in the middle insists on pedantic details. Next time your prof has a conniption over your arrow-pushing shortcuts, just point to this bell curve and ask which side they're on!
