The Whisky Goggles Effect
There seems to be some evidence that Agile and Scrum can nudge the marginally incompetent into being marginally employable. I call this the Whisky Goggles Effect: it turns the 3s and 4s into 5s, but it makes you so sloppy that the 7s and 9s want nothing to do with you. Unable to get their creative juices flowing under aggressive micromanagement, the best programmers leave.
Looks like some sort of distorted perception that is happening when you drunk or something but I can't fully understand what does it mean exactly.
