An entire scientific community could be wrong about something, be expected to know that they are wrong, and for nearly inexplicable reasons persist in being wrong. This happened when the medical establishment embraced Freudian psychology as an explanation of human behavior. In spite of extensive training in the biological and chemical sciences, medical practitioners of Freudian psychoanalysis ignored the basic principle that any scientific explanation of natural phenomena, including human behavior, must be testable. Perhaps physicist-author Lee Smolin is right in suggesting we are witnessing groupthink, again.
