I like this thought, "If, for example, a medical community is divided on whether Treatment A or B does a better job of curing some disease, they should want to get to the bottom of that disagreement, because the right answer matters — lives are at stake. "

And I am going to think about other areas where such disagreements and getting to the roots to find the right answers become necessary.

Question to self and others: What are some other areas where thoughtful people diverge?
