Background: What is Rocket League
Rocket League is a video game. It is essentially soccer/football with cars. It is a highly competitive game, with international competitions and prizes into the hundreds of thousands of dollars.
As with many games of skill, slight variations in player ability can lead to complete blowouts. The game uses a ranking system to sort players by skill level, so that games remain competitive.
These ranks are reset periodically, and players sort themselves anew. After the reset, the first 10 games, players are unranked, and typically play against other unranked players. After 10 games, they are given a rank based on their performance, and typically play against others within 2 or 3 ranks of their own. From then on, your rank changes as you win or lose games.
In my experience, it’s easier to maintain a higher rank in Rocket League than it is to rise out of the lower ranks. I hypothesize that this is due to the relative value of strategy at different ranks: at higher ranks, strategic planning pays off, because the behavior of other players is more predictable; at lower ranks, other players’ behavior is more random, making winning and losing more random for each player on the team. I also think this principle applies more broadly.
I’ll start by saying that I’m not very good at Rocket League, currently around Gold III in 3 versus 3, but I’ll sometimes fall to low gold and even silver when a season starts. A big part of my problem is that I play on a Nintendo Switch, a handheld with a 6-inch screen, which makes precision much more difficult. That sets a low ceiling on my maneuvering and accuracy, but I’m an adequate defender and good at centering the ball for more accurate players to shoot.
My strength is strategy: I pay attention to coverage, I don’t rush in if I’m the last defender, and hurry back after a drive to cover the net. I’m a good defender and midfielder, and I set up shots much better than I shoot.
But when I’m playing against lower-ranked players, that strength is just not that valuable. You can’t read a play when the players are as likely as not to whiff; you can’t set up a shot if no one else can read a play (or, for that matter, connect with the ball); you can’t rely on your teammates to be in the palces they should be. Without the ability to predict other players, strategy is effectively impossible.
Low-level play is more random than higher-level play, because there are a lot of ways to be bad at a game, and relatively few ways to be good. This isn’t only because there are more individuals at the bottom of the ranking. If ranking up requires both the understanding to decide the correct action (what I’ve called “strategy”) and the skill to execute on that decision, then a highly ranked player will have both, while a low-ranked player could be lack strategy, skill, or both.
The effect is a sort of contagion: an individual attempting to cooperate with lower-ranked teammates will be effectively less skilled than they would be when cooperating with higher-ranked teammates, because whatever their other skills, they are unable to be strategic or rational about their choices.
But this is true in domains other than this video game: there are more ways to fail than to succeed; more ways to be poor than rich; more ways to be dumb than smart. For any competition, the highest-ranked individuals will have a combination of skills, and lower ranked individuals will be lacking in one or more of those skills. The more skills it takes to rank highly, the more ways there are to fail to rank highly.
And in any domain where a group of people are competing against other groups, the unpredictability of an individual’s partners will act as a contagion on that individual, by decreasing the value of skills like strategy, reason, even intelligence more generally.
As a result, if highly-ranked individuals tend to team up with other highly-ranked individuals, and lower-ranked with lower-ranked, then the lower-ranked individuals will have a harder time establishing their correct individual rank, because to the extent strategy is a part of the ranking, it will be hidden by their teammates lack of skill. Over time, that will give the highly-ranked individuals an advantage in maintaining their rank.
