It's baffling to me how they are still employed but it's the FA, the back slapping "why don't england managers get the top jobs" organization.
Referees aren't employed by the FA.
https://www.premierleague.com/refereesThis is the problem with these discussions. Most fans don't know the Laws of the Game and they don't know how referees are employed, how they are marked or the disciplinary process when a referee performs below par.
That's not a dig at you personally - it's a general observation.
I probably come across as reactionary but I'm worried that the obsession with referees could lead to unforeseen consequences. The best game in the world is not perfect but it is human. Played by humans, refereed by humans and watched by humans in their hundreds of millions. The potential for fucking it up is real if we play into the hands of the TV companies who would love more controversy and a stop-start game with the chance to have in-game commercials. It's a game most of us have played as kids and its history is rich with great play and dodgy decisions.
What was interesting in the study I linked to (and based on past experience, no one has read) is that social pressures are a good indicator for bias. Studies suggest referees give more home pens than the away pens. They add more time if the home team is behind, and crowd reaction has a measurable impact on referee's decisions. A reasonable assumption is that the modern obsession with refereeing has made them more risk averse than they used to be. If in doubt give the decision that will cause the least controversy in the media.
And as everyone agrees that Liverpool's defence is shite (especially Liverpool fans on social media) it's relatively uncontroversial to award a penalty against the Liverpool defence. If we insist on telling everyone that Lovren (or Henderson) is shite and an accident waiting to happen we cant turn around and say the referee has to assume he's expertly shepherded the opposition player away from the goal.
