When Logic Becomes a Cage

A solution can become so familiar that we stop asking whether it is still the best one.

Psychologists call this the Einstellung effect: a cognitive bias in which a familiar approach dominates our thinking, preventing us from recognising a simpler, better or faster alternative.

Consider the everyday journey. We automatically take our usual route to a destination, even when a new connecting road offers a shorter journey. We know the old road so well that we barely consider another.

A student learns a lengthy method for solving an equation and applies it to every similar-looking problem, overlooking a straightforward solution.

In the corporate world, a leader who once improved performance through tighter supervision applies the same approach to a struggling team. Past success makes it harder to recognise that this team needs clearer priorities and greater autonomy.

Success can teach us a method. It can also make us reluctant to question it.

Familiar ways of thinking carve channels through the mind. With repetition, these channels deepen until we begin to mistake the familiar route for the only possible one. Beyond them, however, lies an entire universe of possibilities.

The danger lies in mistaking familiarity for sound reasoning. Logic helps us examine assumptions; habitual thinking allows them to pass unchallenged. When we stop testing the assumptions behind a once-successful solution, yesterday’s answer can become today’s obstacle.

Perhaps the greatest constraint on imagination is our insistence that every new thought must travel along an old road.

In a BANI world—brittle, anxious, nonlinear and incomprehensible—unfamiliar, disruptive challenges may tempt us to reach for familiar answers. Even when experience whispers, “I have seen this before,” pause. Ask what is different this time.

Take a de novo look: examine the challenge afresh, question your assumptions and evaluate your options.

Let experience inform your judgement without allowing it to imprison your imagination.
