About concensus:

19th century physician Ignaz Semmelweiss endured incredible hostility, ridicule and vilification for the sin of being right about an easy measure for virtually eradicating puerperal ("childbed") fever which had been killing new mothers and infants at an appalling rate.

The vilification persisted EVEN THOUGH Dr. Semmelweiss's patients survived while huge numbers of other doctors' maternal patients succumbed.

As the writer observes in her essay "What Semmelweiss Taught Me": "The tendency to reject anything that challenges established views is a universal psychological phenomenon....It applies not just to science but to every sphere of human life."
