"Most of the mistakes in thinking are inadequacies of perception rather than mistakes of logic"
About this Quote
The intent is classic de Bono: redirect attention from argument to attention. Logic is a tool for moving within a frame; perception decides the frame. The subtext is almost moral in its implication: people hide behind “rationality” to avoid admitting they’re selectively seeing. It’s easier to call someone illogical than to confront that your own categories are stale, your assumptions invisible, your information diet narrow.
Context matters: de Bono built a career on lateral thinking and the idea that cognition isn’t just deduction, it’s patterning. In practice, that means our minds optimize for speed and coherence, not truth. We mistake familiar patterns for accurate ones; we treat first impressions as data; we confuse salience (what stands out) with significance (what matters). The line also anticipates today’s attention economy, where perception is engineered: feeds, headlines, and metrics don’t typically break your logic, they curate your inputs and prime your interpretations.
It works because it shifts blame from “bad reasoning” to a more uncomfortable vulnerability: reality is filtered before it’s ever argued with. The fix isn’t just better logic. It’s better seeing.
