Dr. Paul Eastwick, in his careful taxonomy of attraction and its consequences, offers a phrase I have not been able to put down since I heard it: structural barriers to infidelity. The phrase is clinical, sociological, dispassionate. It is also one of the most honest things anyone has said about human fidelity in years. What it means, stripped of its academic courtesy, is this: we used to be faithful partly because being unfaithful was logistically difficult — because the person you met on the plane disappeared into a terminal and stayed disappeared, because the colleague you noticed noticing you could only be reached by a telephone attached to a wall in a room shared with a spouse. The barrier did the moral work.
We called it character.
Now the barriers are gone. Not lowered — gone. The digital follow-up removes the merciful forgetting that used to rescue us from ourselves. Every encounter refuses to end. The plane lands but the conversation continues in a chat window that has no runway, no terminal, no architectural full stop.
We discover that much of what we called virtue was difficulty wearing a better coat.
Eastwick frames attraction as 'not a problem.' Follow-through is the problem. But this is the language of management, not of experience. Anyone who has been attracted to someone while committed to another knows it begins earlier — at the moment you notice yourself noticing.
I want to take Eastwick's premise seriously — more seriously, perhaps, than he takes it himself — and follow it past the research frame into what it implies about how we actually live. If structural barriers did the moral work, then their removal is not merely a change in social logistics. It is the largest uncontrolled experiment in voluntary ethics ever conducted. We have, in fifteen years, removed from adult life nearly every external constraint that once made fidelity the path of least resistance, and replaced those constraints with nothing except the instruction to choose faithfulness deliberately, continuously, against no friction whatsoever. Speed limits we called prudence.
Scarcity we called temperance. Distance we called fidelity. I do not say that no one was ever genuinely faithful — people have chosen rightly even when choosing wrongly was easy, and those choices were real. But I suspect they were rarer than our national mythology of character requires, and that for most people, most of the time, the structure was doing the heavy lifting while the story of personal virtue was applied afterward, like paint over load-bearing concrete.
This is not despair. It is a starting point. The first step toward faithfulness that means something is admitting that the old faithfulness often meant very little. It was logistical. It was geographic.
It was the closed door mistaken for a chosen one.
What interests me is the intermediate zone Eastwick touches but does not dwell in: the space between noticing and acting, which used to be filled by friction — days of no contact, the impossibility of casual re-encounter, the slow erosion of a face in memory until it became merely a pleasant afternoon rather than a standing possibility. That friction was not merely logistical; it was temporal. Time did the forgetting for us. Now there is no time between impulse and opportunity. The notification arrives before the memory has begun to fade, and the memory, refreshed, becomes invitation.
We are asking people to exercise a muscle at a frequency for which it was never conditioned, and then registering surprise at the rate of failure. The engineering metaphor is ugly but I cannot improve on it: we built a moral architecture rated for occasional load and we are applying continuous load. The collapses are not mysterious. They are structural, which is precisely the thing we refuse to say because saying it would require us to admit that structure was always doing the work we attributed to the soul.
The question that follows is not whether people will be faithful — some will, some won't, as always — but whether we are prepared to build new walls or whether we will persist in pretending walls were never the point. Eastwick's research, read generously, suggests the architecture of relationship — the deliberate construction of barriers, rituals, distances — is not a failure of authentic love but its substance. The plane conversation was honest precisely because the runway was the period at the end of the sentence. Intimacy requires walls. The room is not a prison; it is the condition of depth.
We will not become more faithful by trying harder. We will become more faithful by building the door back and learning to close it on purpose — which is harder than it sounds, because it means admitting the door was always what held us, and choosing it anyway.
