Why Riot's Dunning-Kruger explanation is absolute rubbish.
The Dunning-Kruger effect states that people fail at recognizing their competency level. Or as RationalWiki puts it, "people [sic] are too stupid to know how stupid they are." When Riot applies this to League of Legends, as they often do, they are saying that we all suck at this game, and we couldn't know how much we suck. This explanation is generally used by Riot to rebut any complaints about their matchmaking and elo system.
This really bothers me. And not because Riot is telling me i suck. (That is an illogical statement in its own right, though). I don't play this game aspiring to become pro. I play this game to have fun. And i want to maximize that fun. When i call into question the matchmaking and elo system, i do it because it is not maximizing my fun.
And then, of course, i get the usual Dunning-Kruger explanation in response. So, let us assume their response were indeed true. I suck so bad, that i don't know how bad i suck at this game. Are any of my grievances incorrect now that i have accepted Riot's counter-argument? No. Let me show why.
Typical arguments usually go like this: The matchmaking system does not group me with similarly skilled players, and the elo system does not reflect my true skill. Anecdotally, this seems to be true. We seem to always find the players who amazing ad will successfully 1v5, and the players who you are amazed at just being alive! Also, bronze games can feel a lot like silver games which can feel a lot like gold games.
Now comes the Dunning-Kruger rebuttal. Riot says to the poster, "You suck, and you don't know how much you suck." Poster accepts this statement. Riot to poster, "Therefore, your argument is invalidated." Poster, "Wait, why?"
Can there be different levels of suck? Riot claims this to be true: You can be bronze level of suck, silver level of suck, or gold level of suck (some might argue for plat level of suck and diamond level of suck, but i have not experienced these myself, so i choose to leave them out). Is there evidence to support this claim? No.
Am i matched with similarly skilled players? Riot claims this to be true, as well, but this is based off their unsubstantiated claim of you being in different levels of suck. So, this too is unsubstantiated.
The Dunning-Kruger explanation does nothing to invalidate these two arguments. It is illogical to think otherwise. Stop using the Dunning-Kruger effect as a counter-argument.
