The Unimaginable Model

A model that explains how we often believe in systems and theories that we cannot prove, and how these models can become mistaken for reality, influencing our actions and perceptions.

THE IDEA

THE UNIMAGINABLE MODEL

WHAT DO YOU BELIEVE IN THAT YOU CANNOT PROVE?

Models explain how everything is connected, how we should act and what we should and should not do. But do they prevent us from seeing things for what they really are?

Adam Smith warned against becoming carried away by abstract systems. The question is whether a model’s assumptions fit the situation: internal coherence in a “logical” system does not establish that fit. Kuhn’s account of scientific paradigms also raises questions about how established ways of thinking shape the interpretation of evidence.

We often believe so strongly in models that they take on the status of reality. The ontological argument attempts to establish God’s existence through reasoning about the concept of a perfect being. Kant criticized the argument; he did not endorse the inference that imagining such a being establishes its existence. Ways in which we blindly accept models as “reality” can also be found in our everyday lives: for example, if we are told that humankind is full of greed and egoism, this model of behavior may be internalized and (unconsciously) imitated.

I hate reality but it’s still the best place to get a good steak. Woody Allen

When to use it

  • When evaluating scientific theories, consider whether you are accepting them as reality without question.

  • In personal development, examine the models of human nature you have internalized and whether they are accurate.

  • In business, be aware of abstract systems and models that might not correspond to reality, and avoid being carried away by them.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Ontological proof of God

The ontological argument attempts to move from a concept of a perfect being to a claim of existence. Kant criticized that move. It illustrates why the relationship between a conceptual argument and a claim about reality needs examination.

02

Internalizing the model of human greed

If we are told that humans are greedy and egoistic, we may internalize this model and unconsciously imitate it, thus making it a self-fulfilling prophecy.

✳

A MOMENT TO REFLECT

Put it to work.

  1. What do you believe in that you cannot prove?

  2. What do you believe in despite not understanding the evidence?

  3. What do you believe in despite having no evidence to support it?
