How do we know a belief is true? In this episode, we address the fundamental question of epistemology (the theory of knowledge) through the concepts of the correspondence theory of truth and confirmation bias. We examine, through a fictional cockpit scenario, the mind's tendency to seek out information that confirms its own expectations while ignoring evidence that would refute it, and show how the principle of cross-checking in modern aviation training overcomes this trap. Truth is not what you expect, but what is in agreement with reality.

Epistemology is the branch of philosophy that questions how we know whether a belief is true — the term was coined in 1854 by the Scottish philosopher James Frederick Ferrier. According to the correspondence theory of truth, a belief is true only when it matches reality; believing it or wanting it to be true does not determine its truth.

Confirmation bias, defined by cognitive psychologist Peter Wason in the 1960s, is people's tendency to seek out evidence that supports a hypothesis while ignoring evidence that would refute it. The lesson brings this tendency to life with a fictional cockpit scenario: because a crew has invested in the plan they set before takeoff, they may tend to stick with that plan even when conditions change (plan-continuation bias). The cross-checking principle in modern aviation training — relying not on a single indicator but on multiple independent sources confirming one another — is a practical solution developed against this bias.

The lesson also carries this principle over into corporate decision-making: whether a manager is looking for reports that confirm their own hypothesis, or for data that matches reality, is a test of both strategic accuracy and intellectual honesty.
