Model I is not a philosophy people profess; it is the theory that governs their actual behavior under pressure. Argyris's method for detecting it was the left-hand column exercise, in which practitioners wrote down what they actually said in a conversation (right column) alongside what they thought but did not say (left column). The gap between columns, reliably enormous, was Model I in action.
The AI discourse is a Model I performance at industrial scale. The triumphalist keynote that suppresses evidence of workforce displacement, the skeptical essay that dismisses every capability demonstration, the corporate town hall that announces transformation while foreclosing the questions transformation would require — each is Model I theory-in-use dressed in different vocabularies.
Model II is not natural. Argyris's research showed that almost no one acts in Model II spontaneously, even when they believe they are doing so. The shift requires deliberate practice, structured feedback, and organizational conditions that do not punish the Model II moves. These conditions are precisely what defensive routines prevent from forming, which is why the shift is rare.
The beaver's dam of the AI transition — the structural work of building institutions that direct the river toward life — requires Model II at the institutional level. Without it, the dam-building becomes another Model I performance: control-oriented, defensively structured, and incapable of examining whether the dam is actually holding.
Argyris and Schön developed the models through systematic comparison of espoused theories (what people say they do) with theories-in-use (what people actually do under pressure). The consistent gap between the two — and its specific shape — generated the Model I / Model II taxonomy.
The research required Argyris to develop methods of observation that could capture theories-in-use without triggering the defensive routines that would distort them. This led to his extensive use of detailed case transcripts and the structured exercises that made the gap visible to the practitioners themselves.
Theory-in-use, not espoused theory. The distinction is between what people say they value and how they actually behave when stakes are real. Almost everyone espouses Model II; almost no one practices it.
Four governing variables of Model I. Define goals and try to achieve them; maximize winning and minimize losing; minimize generating or expressing negative feelings; be rational (suppress emotion in self and others).
Three governing variables of Model II. Valid information; free and informed choice; internal commitment to the choice and vigilant monitoring of its implementation.
Compatibility with double-loop learning. Model I is incompatible with double-loop learning because it protects the variables that double-loop learning must examine. Model II is necessary, though not sufficient, for genuine learning under conditions of governing-variable disruption.
