What stands out about our era in particular is a distinct kind of institutional dereliction — a failure even to attempt to form trustworthy people, and a tendency to think of institutions not as molds of character and behavior but as platforms for performance and prominence.

In one arena after another, we find people who should be insiders formed by institutions acting like outsiders performing on institutions. Many members of Congress now use their positions not to advance legislation but to express and act out the frustrations of their core constituencies. Rather than work through the institution, they use it as a stage to elevate themselves, raise their profiles and perform for the cameras in the reality show of our unceasing culture war.

President Trump clearly does the same thing. Rather than embodying the presidency and acting from within it, he sees it as the latest, highest stage for his lifelong one-man show. And he frequently uses it as he used some of the stages he commanded before he was elected: to complain about the government, as if he were not its chief executive.

The pattern is rampant in the professional world. Check in on Twitter right now, and you’ll find countless journalists, for instance, leveraging the hard-earned reputations of the institutions they work for to build their personal brands outside of those institutions’ structures of editing and verification — leaving the public unsure of just why professional reporters should be trusted. The same too often happens in the sciences, in law and in other professions meant to offer expertise.

Or consider the academy, which is valued for its emphasis on the pursuit of truth through learning and teaching but which now too often serves as a stage for political morality plays enacted precisely by abjuring both. Look at many prominent establishments of American religion and you’ll find institutions intended to change hearts and save souls frequently used instead as yet more stages for livid political theater — not so much forming those within as giving them an outlet.

Artists and athletes often behave this way too, using reputations earned within institutional frameworks as platforms for building a profile outside them. When he was inducted into the National Baseball Hall of Fame, the former Chicago Cubs second baseman Ryne Sandberg implored fellow players to remember “that learning how to bunt and hit-and-run and turning two is more important than knowing where to find the little red light on the dugout camera.” When vital institutions across American life fail to produce people who remember that, they become much harder to trust.

The few exceptions to the pattern of declining confidence in institutions tend to prove this rule. The military is the most conspicuous exception and also the most unabashedly formative of our national institutions — molding men and women who clearly take a standard of behavior and responsibility seriously. And that can help us see what we might do to help alleviate the social crisis we confront.
