The story of John Snow in 1854 reminds us that good reasoning corrects weak patterns by letting confidence follow evidence, not fear or public assumption.

Weak induction fed the wrong conclusion; disciplined observation and reasoning corrected it. Confidence became stronger because the explanation fit reality better.
