When using "irrational reason", ensure that the context clearly demonstrates the lack of logic or sound judgment behind the reason being described. Providing specific examples of how the reason deviates from rational thought can strengthen your argument.
Common error
Avoid labeling a decision as based on an "irrational reason" simply because you don't understand it. Intuition and deeply held values can be valid, though not always explicitly logical, influences on decisions. Make sure to examine the reasoning carefully before dismissing it as irrational.
