We were intrigued by the fact that we had so much actual behavior

In the halls where numbers are made to speak, a builder of modern marketplaces utters a quiet revelation: “We were intrigued by the fact that we had so much actual behavior among people on our dating site, OKCupid.” Beneath the plainness is an ancient wisdom reborn: the difference between what people say and what they do, between vows carved in wind and footprints pressed in earth. Declarations are incense; actual behavior is bread. The former perfumes a room; the latter keeps a household alive.

The elders called this difference the gap between the tongue and the hand. In councils and courts, the tongue proclaims ideals; in fields and workshops, the hand reveals allegiance. A profile may swear that kindness matters most, but the message sent at midnight confesses another creed. A questionnaire may praise patience, yet the swift unmatch at the first awkward silence teaches a harsher liturgy. Thus the stewards of OKCupid found themselves keepers not merely of opinions, but of a living archive of choices—the small, unguarded acts by which desire writes its diary.

This is not cynicism; it is a gentler realism. The ancients would have smiled and said: trust the harvest more than the boasting of seeds. When a dating site gathers millions of first glances, hesitations, greetings, replies, and “seen at” whispers, it gathers the weather of the human heart in motion. Patterns emerge like constellations: which questions open doors, which habits shut them, which courtesies lengthen the evening, which vanities shorten it. In such currents the single traveler can learn to steer.

Consider a parable from another century: John Snow in cholera-struck London, who trusted not rumors but the map of footsteps and pumps. By tracing where people truly walked and drew their water, he broke the handle of a well and bent the curve of death. Likewise, Florence Nightingale turned hospital anecdotes into disciplined counts and rose diagrams, letting policy be taught by the conduct of patients and nurses, not the pride of administrators. These are the ancestors of the insight: let actual behavior tutor our designs—first in mercy, then in method.

So the meaning of the saying is double. First, it honors the moral seriousness of data: each click is a candle-flame, small and warm, but together they can light a cathedral of understanding. Second, it charges the maker with responsibility: if you can see how people move, build rooms that reward their best movements—friction against cruelty, ease toward clarity, lanterns for the shy, guardrails for the rash. Metrics are not trophies; they are instruments—lutes that must be tuned to virtues, not merely to growth.

There is also a lesson for the seeker. Read your own trail as carefully as any analyst would. What do your sent messages praise? When do you vanish? Which kinds of profiles make you kinder, and which make you careless? The mirror of actual behavior is stern but healing. It will show you the difference between the lover you imagine and the partner you are becoming. Bring that gap into the light; mend it with practice, not posture.

Take these rites for the road. (1) In your next week on a dating site, keep a brief ledger: one line each night of what you did, not what you felt. Let deeds teach you. (2) Craft your first message to demonstrate attention—reference a concrete detail, ask a question that reveals values; let design follow dignity. (3) If you build platforms, encode kindness: throttle spam, surface reciprocity, make “no” easy and respected. (4) Once a month, run a personal “Snow map”: plot where your time and tenderness actually go; move the handle if the well is poisoning you. Do these, and you will honor the ancient law beneath the modern machine: that truth sits where footsteps gather, and that love grows sturdier when we let actual behavior—ours and others’—be the teacher.
