Of all the lessons that life hands us, one of the toughest is that you can be right about something but still come up holding the smelly end of the stick. Typically this is learned early in life, but far too many of us avoid this harsh truth well into adulthood. And in those cases where being right is literally a matter of life or death, it’s even more difficult to learn that lesson.
For Ignaz Semmelweis, a Hungarian physician-scientist in the mid-19th century, failure to learn that being right is attended by certain responsibilities had a very high cost. Ironically it would also save the lives of countless women with a revolutionary discovery that seems so simple today as to be self-obvious: that a doctor should wash his hands before seeing patients.
