Our old friend Malcolm Pollack has an article in American Greatness entitled "'Mass Formation' is a Two-Headed Coin." Pollack offers the following characterization of mass formation:

“Mass formation” . . . is a newish term for an age-old and long-studied phenomenon: the occasional, and usually quite sudden, arising of passionate and sometimes completely irrational fixations of attention, desire, hatred, or other affinities and aversions in crowds of various sizes, from local mobs to entire societies.

What I will call the COVID Craze is an example of a mass formation. Not everyone who takes precautions is a victim of mass delusion, but surely many are. We see them everyday: people alone on windy beaches wearing face masks, for example. Such behavior is completely irrational and oftentimes issues in hateful displays against people who do not subscribe to the ovine lunacy of the hysterical whose fear has so addled them that they cannot distinguish between efficacious prophylaxis, misplaced moral enthusiasm, and virtue-signaling.

Under what conditions is a social phenomenon such as the COVID Craze usefully referred to as a mass formation? Pollack, citing Dr. Matthias Desmet of the University of Guelph, cites four: free-floating anxiety, social isolation, lack of meaning and purpose in one's life, and anger and frustration.

When all these conditions are met, the collective psyche becomes like a supercooled liquid: given the right nucleus around which to coalesce, a “phase transition” can propagate throughout the system in a very short time. That nucleus is some object that can be plausibly identified as a cause of everyone’s anxiety and frustration, and the allure of attacking and eliminating it through collective action becomes, for many people, irresistible. The reason for [cause of] this is sensible [understandable] enough, because it [the attack and attempted elimination]  addresses [alleviates] , in a single stroke, all of the stress-conditions listed above: it offers, at last, a concrete object to which free-floating anxiety can attach, about which something can be done; it provides a much-needed basis for the reconstruction of social bonds; it puts before the group a great purpose toward which everyone can direct their energy; and, perhaps most attractive of all, it creates a common enemy toward which the people can channel their anger. (I added the words in brackets to aid my understanding.)

Those who stand in the way of this collective purpose, as well as those who merely lack enthusiasm for the cause, have consciously excluded themselves from this new social bond, and so they are easily, and usually eagerly, seen as enemies who must be isolated or eliminated. This polarization in turn encourages increasingly conspicuous signaling of one’s fidelity to the group and its cause. The more costly those signals are at a personal level, the more they signify commitment to the new social bond, and the more respect they purchase from the in-group—even if (or, perhaps, especially if) they do nothing that is actually effective in solving the underlying problem.

Malcolm mentions COVID, but I would have liked to have seen other examples. I will suggest one of my own. The President of the United States has recently made a delusional statement to the effect that white supremacy is the greatest threat the nation faces.  Because Joseph Biden is non compos mentis,  there is a certain risk in attributing this thought to him as something he himself believes. It is however safe to say that he is serving as the mouthpiece of a large group of  people who either believe it, in which case they are delusional, or merely pretend to believe it for their own personal gain, in which case they are not delusional but immoral both in their mendacity and in their willingness to put personal profit over the good of the country that has made their success possible. The latter bunch include the 'woke' capitalists and all manner of 'woke' careerists in government, academia, the churches, and elsewhere who seek to promote themselves by spreading lies and slanders.

Malcolm tries to be even-handed in his piece, as witness:

It is also a dangerous conceit to imagine, as many on the Right seem to be doing with this viral idea, that it currently manifests itself only with regard to the COVID panic, and only on the Left. 

It’s important to keep in mind that the four conditions enumerated by Desmet are amply met throughout modern society, across political and ideological lines, and that as long as our various factions struggle to live together, any mass-formation on one side is likely to increase anger and stress on the other, in a destructive feedback loop.

Pollack is right on the first count: the COVID Craze (as I call it) is not the only manifestation of mass formation 'psychosis.' On the second, however, he may be giving aid and comfort to a false moral equivalentism.  Left and Right are not moral equivalents. The Left is far worse. I grant that there are some extremists among those on the Alternative Right. But they are few and far between, and of little consequence, in comparison to the extremists who dominate the Left. The Left is morally and indeed intellectually inferior to the Right by orders of magnitude. The contemporary 'woke' Left in the USA, which controls the Democrat Party, is mindlessly extremist and destructive in respect of almost all issues of importance. To name just a few mindlessly extreme and destructive ideas and policy proposals: the ethno-masochistic notion that mathematics is racist, which of course implies that hard science (physics, e.g.) is racist as well; the Pelosian idea that "borders are immoral" and the corresponding Democrat policy of allowing anyone from anywhere into the country without any control or vetting; the absurd notion that defunding the police and eliminating cash bail are 'reforms' that will reduce crime; the incessant Orwellian subversion of language as for example the misuse of 'insurrection' to refer to trespassing; the erection of monuments and memorials to the worthless while tearing down those that commemorate great and worthy Americans. I could cite another dozen examples with ease. 

I'll leave it here. The combox is open for Malcolm's response and for any comments of anyone.
