Making a rational decision involves an analysis of the inputs (information, assumptions, and biases) that form part of your reasoning, as well as the outputs (decisions, assumptions, and biases) that result from your reasoning.

The intellectual roots of rationalising dates back to Socrates, who developed a method of probing questioning that forced people to justify their confident claims to knowledge. Socrates established that one cannot depend upon those ‘in authority’ to have sound knowledge and insight. He demonstrated that persons may have power and high position and yet be confused and irrational.

Making a rational decision is like questioning continuously, every claim that is made. It is drilling down to clarify meaning, eliminate inaccuracies, improve comprehension, and strive for intellectually honest results.
