There is number of things to unpack. First there is both conscious and unconscious (judgmental) bias that takes place in all officiating. And you can have conscious bias without the intent to influence the outcome. “Rigging” is a conscious bias WITH the intent to influence the outcome.
A good example of “conscious bias” is the crew chief in a baseball game that had a number of “run ins” with a particular manager. The crew makes the decision he’s “putting the manager on a short leash today”. That is a form of conscious bias. The management of the circumstance was “pre-determined” by the crew chief instead of it being determined by the situation as it happened. A non biased position would prevent the inference of previous experiences on the determination of the current one. This conscious bias by the crew chief wasn’t done with the intent to influence the outcome (ie: “rigged”) but there have been times it has.
An unconscious bias can be influenced by a number of factors both internally and externally. There is sometimes “the David versus Goliath” situation where the official gives preferential treatment to the one (or team) they have unconsciously deemed “weaker or disadvantaged”. The better side of our human nature wants us to protect those we feel are weaker. The home field advantage is an unconscious bias that happens all the time. The official makes a call because of “cognitive dissonance”. In other words “I really don’t know if I saw it but others reacted as though it did so I better call it”. Why? Because it is emotionally uncomfortable to be on that island by yourself. The “seed of doubt” unconscious bias - “team X does this” or “this player is known to do y”. Those types things shouldn’t play into it, but they do. And there are many others
Do i think officiating is “rigged” against Alabama? No but I do believe there is at times a conscious bias by officials. And when it comes to both unconscious and conscious bias, as long as humans are making the calls, you will NEVER remove it. The best can do is hope to manage fundamental fairness across the board by getting rid of those that are incompetent.
And finally, if you are a victim of this type biases, the only way to manage it is to play a cleaner, more disciplined game than the other guy. The very thing CNS continually brings up. You can’t control another’s actions. You can control yours.
