Core Idea

Mental models are deeply ingrained assumptions, generalizations, and internal images that influence how we understand the world and take action - often operating invisibly to constrain thinking and block organizational learning.

What Mental Models Are

Mental models are the deeply held internal pictures and assumptions about how the world works that limit us to familiar ways of thinking and acting. They are the lenses through which we interpret reality, shaping what we perceive and how we respond to what we see.

Kenneth Craik first introduced the concept in 1943, proposing that the mind constructs “small-scale models” of reality to anticipate events and predict future outcomes. These internal frameworks operate largely below conscious awareness. We rarely examine them critically, yet they profoundly influence every decision we make and every action we take. A manager might hold a mental model that “people only work hard when closely supervised,” leading to micromanagement behaviors that actually undermine trust and initiative.

Why Mental Models Matter for Organizations

Mental models become particularly problematic in organizational contexts because they often remain unexamined and unquestioned. When teams share unstated assumptions, those assumptions become invisible constraints on innovation and adaptation.

Key characteristics of mental models:

  • Invisibility: Often unconscious and unexamined, making them difficult to challenge
  • Persistence: Deeply ingrained through years of experience and cultural reinforcement
  • Pervasiveness: Shape both perception and action across all organizational decisions
  • Blocking power: Prevent new insights from emerging and new practices from taking hold
  • Gap between theory: Create disconnect between “espoused theories” (what we say) and “theories-in-use” (what we actually do)

Chris Argyris and Donald Schön identified this critical distinction: espoused theories represent the beliefs we claim to hold and the actions we say we will take, while theories-in-use are the actual mental models that govern our behavior. A consultant might espouse joint problem-solving with clients (espoused theory), yet recordings reveal unilateral control and dismissal of client input (theory-in-use). This gap between what we say and what we do often remains invisible without deliberate inquiry.

The most dangerous mental models are those we don’t know we have. They create blind spots that prevent us from seeing alternatives, recognizing patterns, or adapting to changing circumstances. Cognitive psychology research shows these models function as schemas—mental frameworks that help us process information quickly but can also trigger confirmation bias, where we unconsciously seek data that reinforces our existing beliefs while dismissing contradictory evidence.

Working With Mental Models

The discipline of mental models involves surfacing, testing, and improving our internal pictures of the world. This requires developing skills of both reflection and inquiry:

Reflection and inquiry practices:

  • Exposing thinking: Making one’s own reasoning visible and open to questioning
  • Balancing inquiry and advocacy: Learning to genuinely explore others’ views, not just argue for your own
  • Testing assumptions: Actively seeking data that might disconfirm your beliefs
  • Distinguishing data from interpretation: Separating observable facts from the stories we tell about them
  • Inviting challenge: Creating psychological safety for others to question your assumptions

This work is uncomfortable because it requires vulnerability - admitting that our view might be incomplete or wrong. Yet this discomfort is precisely what enables learning. When team members can surface and examine their mental models together, they can identify and challenge the hidden assumptions that block organizational effectiveness.

  • Personal-Mastery - Requires examining one’s own mental models to see reality more objectively
