“As all this suggests our relationship with evidence is seldom purely a cognitive one. Vilifying menstruating women bolstering anti-Muslim stereotypes murdering innocent citizens of Salem plainly evidence is almost always invariably a political social and moral issue as well. To take a particularly stark example consider the case of Albert Speer minister of armaments and war production during the Third Reich close friend to Adolf Hitler and highest-ranking Nazi official to ever express remorse for his actions. In his memoir Inside the Third Reich Speer candidly addressed his failure to look for evidence of what was happening around him. "I did not query a friend who told him not to visit Auschwitz I did not query Himmler I did not query Hitler " he wrote. "I did not speak with personal friends. I did not investigate for I did not want to know what was happening there... for fear of discovering something which might have made me turn away from my course. I had closed my eyes." Judge William Stoughton of Salem Massachusetts became complicit in injustice and murder by accepting evidence that he should have ignored. Albert Speer became complicit by ignoring evidence he should have accepted. Together they show us some of the gravest possible consequences of mismanaging the data around us and the vital importance of learning to manage it better. It is possible to do this: like in the U.S. legal system we as individuals can develop a fairer and more consistent relationship to evidence over time. By indirection Speer himself shows us how to begin. I did not query he wrote. I did not speak. I did not investigate. I closed my eyes. This are sins of omission sins of passivity and they suggest correctly that if we want to improve our relationship with evidence we must take a more active role in how we think must in a sense take the reins of our own minds. To do this we must query and speak and investigate and open our eyes. Specifically and crucially we must learn to actively combat our inductive biases: to deliberately seek out evidence that challenges our beliefs and to take seriously such evidence when we come across it.”
“It is not what we believe, but why we believe it. Moral responsibility lies in diligently weighing the evidence. We must actively doubt; we have to scrutinize our views, not take them on trust. No virtue attached to blindly accepting orthodoxy, however 'venerable'...”
“Good and evil keep happening in this world. It just takes a little longer for us to take the bad in our stride. And just when we think we've come to terms with bad, we're shocked to be haunted by that one query whose answer is ever as elusive - why on earth did it have to happen to me ?”
“In college, in the early 1950s, I began to learn a little about how science works, the secrets of its great success, how rigorous the standards of evidence must be if we are really to know something is true, how many false starts and dead ends have plagued human thinking, how our biases can colour our interpretation of evidence, and how often belief systems widely held and supported by the political, religious and academic hierarchies turn out to be not just slightly in error, but grotesquely wrong.”
“We can learn from history, but we can also deceive ourselves when we selectively take evidence from the past to justify what we have already made up our minds to do.”
“What should we think of someone who never admits error, never entertains doubt but adheres unflinchingly to the same ideas all his life, regardless of new evidence? Doubt and skepticism are signs of rationality. When we are too certain of our opinions, we run the risk of ignoring any evidence that conflicts with our views. It is doubt that shows we are still thinking, still willing to reexamine hardened beliefs when confronted with new facts and new evidence.”
