Quote by Milton Friedman
The only relevant test of the validity of a hypothesis is comparison of prediction with experience.

Summary
This quote suggests that the true way to determine the accuracy of a hypothesis is through the comparison of its predictions with actual experiences or outcomes. In other words, simply proposing a hypothesis is not enough; one must gather data and evaluate if the predictions made based on the hypothesis align with the real-world results. The quote emphasizes the importance of empirical evidence in validating hypotheses.
