If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence.

Summary

This quote highlights the inherent bias in human cognition. When confronted with a fact that contradicts our instincts or preconceived beliefs, we tend to question and analyze it rigorously. Unless there is strong and compelling evidence, we are likely to reject it. Conversely, if we are presented with something that aligns with our instincts or desires, we are more prone to accept it, even when the supporting evidence is minimal. This quote underscores the subjective nature of human decision-making and the influence of personal biases on our beliefs and actions.
