The prospect of racial bias in regards to referees in the Premier League intrigued me the most during my research, with the effect that a yellow card can have on the overall result of the game often underrated. A booking, especially one given to an integral member of the team, could change the game plan of said player, perhaps rendering them unable to make a tackle with the knowledge that he may be cautioned for the second time. Sanctions could also have implications for a player’s wage rate if a club’s pay structure is related to disciplinary actions. Both of these factors and many more would put clubs with a large number of darker skinned players at a distinct disadvantage and if there is a racial bias shown in referees, especially in a high-profile league like the Premier League, this type of behaviour could result in extreme backlash from fans, players and organisations alike worldwide. All in all, this research prompted me to delve deeper into this proposed form of discrimination through a unique and detailed dataset and interrogate whether or not there is a relationship between race and disciplinary sanctions, which will now be discussed in the following section.
