The Lost Equation: Understanding and Knowing What to Do
The more that we "understand" or "talk about" these days, the less that we seem to know what to do
There’s an old formula, so basic it was rarely stated: To understand something is to know what to do about it.
Understanding wasn’t a feeling or a position or a display. It was operational. You understood a problem when you could act on it effectively. You understood a domain when you could navigate it. The proof of understanding was in the doing.
Confidence, in this model, was a natural byproduct—a readout of genuine competence. You felt assured because you knew what to do. The internal state tracked an external reality. The gauge measured actual pressure.
Somewhere in the last decade or two, this equation came apart.
What emerged in its place is a different architecture entirely. Understanding became symbolic—something you signaled rather than possessed. To “understand” an issue now means to have the right position on it, to use the correct vocabulary, to display appropriate concern or outrage. The test is social, not operational. Does your understanding read as understanding to the relevant audience?
Confidence underwent a similar inversion. Rather than being downstream of competence—an effect of knowing what to do—confidence became upstream. A cause, not a consequence. You project confidence to produce effects: engagement, followers, status, influence. Whether there’s anything underneath is secondary. Often irrelevant.
The attention economy selects for this. What gets rewarded is the performance of understanding, the display of confidence. The feedback loop runs through likes and shares and engagement metrics, not through contact with reality. You can project “I’ve got this” indefinitely because nothing ever tests whether you actually do.
The result is a world full of people who present with absolute conviction on matters they couldn’t act on competently for five minutes. Who have opinions on everything and operational capacity on very little. Who feel confident because confidence is what you perform, not what you earn.
And they’re not faking it, exactly. Many have genuinely lost the distinction. The performance has become invisible to the performer. They feel like they understand because understanding now means having the right signals. The old equation—understanding as knowing-what-to-do—isn’t even available as a reference point.
Meanwhile, things don’t work.
Systems are failing in ways that seem inexplicable given how many credentialed, confident people are managing them. Institutions staffed by people who present with authority produce outcomes that suggest no one actually knows what to do. Problems that should be solvable persist and metastasize. The gap between the confidence on display and the results on the ground grows ever wider.
Everyone senses this. The discourse is saturated with the feeling that something is wrong, that the people in charge don’t actually have it, that the competence isn’t there. But we struggle to name it, because the old vocabulary—understanding, competence, knowing what to do—has been colonized by its simulacrum. How do you say “these people don’t understand” when they present every signal of understanding? How do you say “they don’t know what to do” when they project such confidence?
The problem isn’t that people are pretending. It’s that the culture has lost the ability to distinguish the map from the territory. We’ve optimized so heavily for the appearance of competence that we’ve forgotten what competence actually is. The gauges all show pressure. But the system isn’t pressurized. And slowly, then suddenly, things stop working.
The recovery, if it comes, will require something simple and difficult: reinstating the old equation. Understanding means knowing what to do. Confidence is earned by demonstrated capacity. The test is operational, not social.
Until then, we’ll remain confused—watching people who seem to know, who certainly act like they know, who are credentialed and confident and fluent—and wondering why nothing they touch seems to work.
