In your example, the aggressive alt-right "individualist" would be the equivalent as the high school rebel who is just acting a rebel and conforming to their adopted group.
Conformists are essential for any group cohesion. I imagine a key part of a conformist in any group is to define the out groups.
Maybe it's just conformists with progressively smaller groups.
“Aggressive independence” for its own sake (at scale) can simply degrade into its own form of ironic groupthink.
Psychology researchers know this, but in the folk psychology there is this assumption that you can observe people in context and that's how they are.
Yes and no. In a purely objective context conformity is a personality mode shaped by a person's social reference group and the devotion or conformance to a single idea rests on the reinformance of the local group. For a highly conformant person you can change their opinion on a subject by dropping them into a different social context for a month at which point the devotion to a particular subject will be replaced by devotion in a different subject.
Perhaps the most defining characteristic of somebody extremely non-conforming is the potential and frequency for original and potentially unpopular decisions. From extremely conforming people originality is met with immediate hostility. In that hostility the person may not even realize they are emotional first without any consideration for the validity of that emotion.
I'd submit a common case of that is someone with a new idea and being confronted with all the reasons it will never work.
And that really does seem like a function of personality. The people saying why it won't work aren't being close-minded; they're gaving the idea a listen and thinking about it critically. They're may not even being outwardly rude. It's simply an unconcious preference to critique and find flaws.
That seems to fit with PG's claim that "The call of the aggressively conventional-minded is 'Crush <outgroup>!'". Naturally that would extend to disobeying the rules of the outgroup, perhaps solely because the outgroup proposed them.
I myself remember feeling the strong pull of both "types" and I'd struggle to define myself clearly as either. (although I suspect I'm more frequently conformist than my overly flattering self-image depicts)
Sounds like he is trying to say "Crush <outgroup>!" to me...
Someone can be both aggressively conformist over some issues (and towards some groups) and aggressively independent over others.
In fact if you picture a stereotypical conspiracy-minded alt-right individual then the exhibit both behaviours at the same time about the same group. (individualist) "I won't do x because the government tells me I should" and (conformist) "How dare those liberals in my town break the social conventions I feel strongly about!"
It's not hard to come up with an equivalent caricature for the left.
Every time you read a way of dividing the world into types - think of an example of someone who is multiple types. It's very easy in nearly all cases.
