Punishment
http://open.lib.umn.edu/intropsyc/chapter/7-2-changing-behavior-through-reinforcement-and-punishment-operant-conditioning/ The link above is just so people can get familiar with the terminology and general knowledge.
The link below, points out the part I want to specifically discuss. https://quizlet.com/121225710/psychology-chapter-6-learning-flash-cards/
Factors that influence the effectiveness punishment -timing -intensity -consistency Timing is the most effective when applied during the misbehavior or as soon afterwards
Intensity -punishment has to fit the crime -too mild=no effect -severe punishment=adhesive side effects
consistency -must be applied consistently -parents need to be in the same page/react the same
Problems with Punishment -doesnt teach/promote alternative acceptable behavior -may produce undesirable results/hostility/fear/passivity -may be temporary -can model aggression
Now let's consider League.
Timing - Some accounts may exhibit an unwanted behavior for hundreds of games. Best case scenario, IFS triggers a punishment minutes after a game. Still considered delayed, because punishments are handed out after a game not after the offense.
Intensity - All offenses can be punished with the same intensity. This is the tier system. While mild offenses are slower up the tier system, ultimately, they receive the same punishment as severe offenses. One would have to argue repeat mild offenses are equal to severe offenses.
Consistency - I'm a little split on this one. Every instance is not always punished. Consider intentional feeding cases. It usually takes a history of offenses before punishment is issued. I would say, well defined offenses are consistently punished. The more subjective offenses are not consistently punished.
The problems with punishment in League context:
Teaching in game play context - there is almost no teaching. It is very hard to show how game play would be different with alternative actions. There is a lack of "teachers".
Teaching in chat context - There is almost no teaching for positive chat. There is teaching for muting or neutral chat.
Undesirable results - I think there is an argument to be made. Some punished players turn to "troll accounts". Some punished players become afraid to use chat all together.
May be temporary - I think we see this a lot. I don't have actual data though. Keep in mind, mild offenses usually require a threshold before being punished. It may take some time before the temporary state of reform is discovered. The punishment it self is pseudo temporary because of the ability to create new accounts.
Can model aggression - That is a tough one. I feel Riot shows little empathy. I'm not entirely sure that constitutes being aggressive. EDIT: The modeling of aggression shows in the communities unwillingness to come to peaceful resolutions. The community mutes and reports the instant they see something objectionable. Furthermore, they desire the offender to be banned without question.
