The three levels run on time scales orders of magnitude apart

What it is

The three levels differ not only in what they evaluate but in how long one judgment takes, separated by orders of magnitude: the visceral level is settled within milliseconds to a few hundred milliseconds of stimulus onset, before any deliberative evaluation; the behavioral level stabilizes across action–feedback loops running seconds to minutes; the reflective level keeps integrating and revising over days to years. The same product can therefore be out of sync with itself — the three levels are not three ratings of one experience but three processes running on separate timelines.

Why it happens

The time-scale gap is not one process running at different speeds — it is a difference in encoding. The visceral level is an immediate affective reaction: the appraisal is issued as perception completes, without waiting for functional or semantic analysis, and it is not updated by the course of use — the first glance is that level's final verdict. The behavioral level is an action–feedback loop: each action returns an outcome, the judgment updates once per cycle, stability takes several cycles, and the operation itself paces it in seconds to minutes. The reflective level is narrative reconstruction: experience is woven into a story of what it means for me, every retelling revises the story, and so this level's verdict stays under revision over days and years. Because the encodings do not translate into one another, the levels drift apart: a visceral verdict is not refreshed by later smooth use; a behavioral good feeling dissipates unless it enters the narrative; the reflective level can overwrite the record of both lower levels with a rewritten story. One product thus exists in three concurrent versions — the glance, the feel right now, and the story being retold.

Studying it

The tradition showing affect precedes deliberation supports the millisecond-to-hundred-millisecond figure: affective primacy holds that like/dislike judgments can form when semantic processing cannot complete — under very brief exposure, masking, or memory load, stable preferences still emerge. Trait judgments from faces shown for roughly 100 ms match unlimited-exposure judgments, with longer exposure raising confidence rather than changing the verdict; visual appeal ratings of web pages at about 50 ms align closely with ratings after far longer exposure. The behavioral loop's pacing comes from response-time and feedback-manipulation studies in interaction research. The reflective time constant can only be approached with longitudinal designs: delayed recall and interviews across weeks or months, tracking how the narrative drifts. Methodological note: each level must be sampled inside its own time window — a questionnaire administered after the session can never see the visceral reaction completed in the first second; and when comparing "which level dominates," misaligned measurement times produce differences that are artifacts of when you measured, not real cross-level priority.

Where it stops holding

The scales describe the pace at which each judgment forms, not a serial order — the levels run in parallel, and once a reflective conclusion exists it can re-tint the visceral response within a few hundred milliseconds: a returning user's first glance at a familiar brand already differs from a first encounter. The magnitudes are orders, not constants: behavioral "seconds to minutes" stretches with task structure (a long multi-step task can pull it to hours), and reflective "days to years" depends on how often the experience gets retold. And a short feedback cycle does not make a level more important — same-day testability only means evidence arrives fast, not that returns per level are higher.

Applying it

• Tag every design decision with its target level and the time at which evidence should surface: visual and material decisions follow the visceral pace and can be retested same-day with exposure tests; flow and feedback decisions follow the behavioral pace and need task sessions covering several loops; meaning and identity decisions follow the reflective pace and need weeks or more, judged by retention and active advocacy.
• Do not veto a slow-level change with a short-window metric: a reflective intervention flat on one-week metrics means the window is shorter than the level's cycle, not that the intervention failed; likewise, do not expect a visceral fix to move retention weeks later.
• To validate: in retrospectives, check each metric's measurement time against its target level's window; any conclusion measured a full window off its level is marked for re-measurement rather than used as a decision basis.
