I interpret the engagement with conservative ideas Scott's describing a little more straightforwardly. Lots of people are inundated with Mrs. Grundy leftist takes on social media. They're smart enough to try and figure out what they really think. So they say things like "Oh, I heard about that guy in South Carolina. Instead of knee-jerk condemnation, let’s try to form some general principles out of it and see what it teaches us about civil society.”
This isn't countersignaling. It's just signaling. This isn't making fun of anybody, and it's calling for straightforward civil discourse in terms nobody could possibly mistake for anything else.
I notice that a key characteristic of signaling vs countersignaling is that for regular signaling you are paying with resources while for counter signaling you are paying with risk. That is - the credibility of regular signals is derived from false signals being more costly than true signals, so it's harder to justify sending them. The credibility for countersignals comes from the risk of the signal backfiring, which should be have a greater probability when the signal is false, deterring false signalers.
Calling for a civil discourse is not a signal that requires much cost to send. So if it was a regular signal, it was at most a virtue signal. But even thought it comes "in terms nobody could possibly mistake for anything else", it can still backfire. If you are perceived as a person who often gets emotional in discussions and engage in personal attacks and general demagogy, calling for a civil discourse can paint you as a hypocrite who only wants civil discourse when it fits their agenda. If you consistently discuss civilly, the risk for that happening is much lower.
So, this may not be a strict by-definition countersignal - after all, the naive interpretation of the signal is exactly what you are trying to signal - but I still find it's mechanics to be much closer to countersignals than to traditional signals.
Nuanced Countersignaling
Scott Alexander described countersignaling as following a barber-pole pattern. Or, as he says in Friendship is Countersignaling:
I think of this as a subtype of countersignaling - nuanced countersignaling. The primary goal here to distinguish an actual level n from a similar-but-worse level n-1. This is done by sending an n-2 signal while you're at level n.
Note that under this theory, sending an n-3 signal is "dangerous" for the purpose of countersignaling as level n. After all, n-3 would be how an n-1 countersignals. Countersignaling at level n-2 is the only way to unambiguously countersignal level n status.
Extreme Countersignaling
By contrast, with extreme countersignaling, the idea is to send the most extreme possible countersignal. If signals are on a spectrum from 10 to -10, extreme countersignaling is when a person at level 10 illustrates this by sending a -10 signal. A person at level 9 can only get away with sending a -9 signal.
I think this is what's going on in Scott's dialog in the post about friendship.
Let's say that friendship is on the scale of solid friends > budding friendship > acquaintances > strangers > enemies. If Scott and Becca are solid friends, nuanced countersignaling would call for a dialog where they pretended to be acquaintances.
Note that this imaginary dialog doesn't come off as particularly funny or friendly, which might be because my writing sucks, but is also predicted by extreme countersignaling. They need to go all the way to pretending to be enemies to illustrate just how solid their friendship really is, which is how they actually behave in the original dialog above.
Fragility Of Countersignaling
Countersignaling is hard to get right. Under nuanced countersignaling, sending a level n-1 signal by accident puts you at risk of being taken as actually being at level n-1, while sending level n-3 or lower signals would also serve as countersignaling signals for those at lower levels. Level n-1 could also countersignal at level n-3, so an n-3 countersignal may not serve to distinguish level n from level n-1 as well as an n-2 countersignal.
Under extreme countersignaling, sending a -n countersignal is best. If the countersignal is not extreme enough, it signals timidity or distance. If it's too extreme, it might be taken as distressing.
This accounts for the outcome of Scott's second dialog:
Here, there's no threat of physical violence. It's not as extreme as the dialog between Scott and Becca. This corresponds to the lower level of Scott and Pat's friendship.
Under a nuanced countersignaling theory, Pat storming out of the room should have been more unbelievable than his "you owe me big time" comment. But instead, "you owe me big time" was effective countersignaling, and storming out of the room provoked distress, which is what extreme countersignaling predicts.
In general, I think that extreme countersignaling is more common than nuanced countersignaling. It doesn't follow the "barber-pole" model Scott proposed.
Fashion and Politics
Scott asks some interesting questions about fashion.
Here, the "countersignaling" GHETTO shirts are appropriating the symbols not of class n-2, but of class -n. I agree with Scott that the "last year's fashion faux pas" seems like an example of nuanced countersignaling. Perhaps we have both going on in the world of fashion.
Scott then goes on to apply countersignaling to politics.
The "libertarian-conservative screeds" bit is made up, but let's pretend like it's real, actually brilliant, and Scott's right about the countersignaling. The most obviously countersignaling bit is the phrase "THE IDIOTS ON THE LEFT." Everything else before and after that is the bizarre brilliancy. And when this imaginary libertarian countersignals, he does it not by aiming for some sort of dumber-than-smart but smarter-than-dumb n-2 level, but for an all-caps "THE IDIOTS ON THE LEFT" ranting tone. This is extreme countersignaling!
Everything In Its Place
One common feature of all these examples is that the countersignaling is confined. The doctors are having a brief exchange in the middle of their rounds. The GHETTO shirt is just a shirt, one part of the wardrobe, worn occasionally, and probably doesn't actually look GHETTO overall. The libertarian-conservative screed is 4% countersignaling, 96% argument and analysis.
Countersignaling is also useful as a self-signal. If you intuitively feel that you can get away with a little bit of countersignaling, it's a sign that you've sent a sufficiently powerful signal to have the countersignal be interpreted correctly. But countersignaling is just the cherry on top of the straightforward signaling sunday.
This is why it's hard for me to agree with Scott in his analysis of a reality-based conservative smart-person reaction against Mrs. Grundy leftism as being explained by countersignaling. Countersignaling seems to function best when it's a small part of a much larger straightforward signaling context. It's not a lifestyle - just a bit of fun.
The brilliant mathematician puts a "Don't Tread on Me" bumper sticker on his Tesla? Countersignaling. The brilliant mathematician spends an inordinate amount of time engaging with whatever conservative news stories float across his Facebook feed? Before too long, it's not countersignaling anymore - just reversed stupidity.

Like a computer, a relationship can sometimes be rebooted by turning it off and turning it back on again. I read these people as acknowledging that the relationship is at a -7 ("instead of a knee-jerk condemnation"), and are sending signals as if it were at a 0 ("let’s see what it teaches us about civil society"). This is neither extreme nor nuanced countersignaling. It seems to me that this is just a fail-safe social move that is pretty widely recognized. If things are getting too bad, we can revert to the polite civility that might be extended at a gathering of strangers.
So I'd agree with Scott in finding some hope in our cantankerous political situation. But instead of seeing an intelligentsia oscillating between whichever political opinion is just out enough to be hip, I see an intelligentsia being the first to recognize the dynamics of the social situation and extend an olive branch to the other side. They're banking on others finding this appealing and joining in.
