We must have government banking because of the panics of the nineteenth century. We must have government health care because of the illnesses of the twentieth century. We must have government gun ownership because of the shootings of the twenty-first century.
Following tragedies, people seem to systematically wish to be dominated by authorities, to surrender their own freedom and rob others of theirs. Why?
We always have a layer of authority-worship ready to pop out, illustrated most memorably by Stanley Milgram's infamous experiment: volunteers kept administering what they thought were electrical shocks to actors who feigned cries of pain, past what would appear to be the point of safety – solely because a guy in a white lab coat told them to. The bias has been used, for example, to attempt to explain high CEO pay, or the willingness of otherwise ordinary people to torture and murder innocents simply because a guy in a uniform told them to.
Indeed, Milgram began his experiments around the time of the Nazi trials, motivated by the issues they brought up. And the appeal of authority has not faded over the past seven decades. People still "just follow orders," even when it means violating innocents. Just look at the TSA today.
Horrible as the appeal to authority is, and though it is related to the cower-to-power effect, it doesn't fully explain our tendency after crises to want to further strengthen an already centralized force.
It's not that the government commands us to give up our freedom and we acquiesce. It's worse. Many of us beg to be dominated.
This tendency to kowtow can't be merely an appeal to authority, because in the wake of tragedies Democrats do not support giving more power to Republicans, nor does the reverse occur, no matter which party is in the majority. On the contrary, devastating events tend to polarize people into supporting "their" respective parties, even if there are no meaningful differences between the major parties. So it's not simply placating whoever is in power, though that is part of it; it is about something more.
It seems to be more of an instinct to centralize, to manage the situation, to lock everybody down, to tell people what to do and how to do it so it can't happen again. This instinct is the illusion of control.
The illusion was first documented in 1975 by psychologist Ellen Langer. The title of one of her articles explains it best: "Heads I Win, Tails It's Chance." In other words, if I win, it is because I am skillful and smart and handsome. If I lose, it is just bad luck.
Such thinking is pervasive among gamblers, though not usually successful ones. It also has strong and negative consequences in medicine: One potential problem of too many screening tests is that patients and doctors feel an irresistible urge to act, to do something, even after fallible tests that produce false positives on a consistent statistical basis.
In banking too, the Dodd-Frank laws and the regulations they will unleash over the next few decades were a knee-jerk response to the financial crisis, a response to even further centralize money and banking in the hands of a privileged few. Now, firearms ownership is poised to be rationed to the government too.
