While completing How We Decide, it created me to think about how much of our mind many people probably do not even begin to understand. In many ways actually, we have so many preconceptions, that what we think we “know”, is actually incorrect. The chapter on “The Moral Mind” was a very strong example of this, and I found this to be very interesting and one of my favorites, certainly out of the last few chapters of the book.
Lehrer begins this chapter talking about a man named John Wayne Gacy. Gacy was a successful and well-liked man. He was “pillar of the community” and was voted one year as the Man of the Year by the local chamber of commerce. He had a wife, and what seemed to be a normal, overall good life. Sadly, his whole life was carefully crafted lies. One day, Gacy’s wife noticed a putrid order coming from underneath their house. Gacy tried to cover the smell with a 50-pound bag of lime and told her it must just be a dead rodent or a sewage leak. The smell would not go away, and he then even went to the extent of filling the crawlspace under the house with cement. The smell still was evident, and then finally became found to be rotting bodies. “On March 12, 1980, John Wayne Gacy was convicted of murdering thirty-three boys” (Lehrer).
Gacy was a psychopath. Psychopaths make terrible moral choices because of a specific brain malfunction. Morality can be a very unclear concept, but simply, it is the choices made about how other people should be treated. Psychopaths cannot consider other people’s feelings; they can’t sympathize with their states of mind. Their logic is perfect, but what causes this condition is the damage of their emotional brains. This is what makes them dangerous. They have what is seemed to be an “emotional emptiness” causing them to feel nothing. Like Gacy, even after something as terrible as causing multiple murders, they feel no remorse or have anything on their conscious. “They can lie with impunity” (Lehrer). Whereas normal people would show symptoms of nervousness when lying, psychopaths are not even the slightest bit anxious. A lot of them, instead of their blood pressure and pulse rate rising, they are actually calmed by acts of violence.
Lehrer states that the absence of emotion makes the most basic moral concepts incomprehensible. A quote from G.K. Chesterton, makes the concept clear, “The madman is not the man who has lost his reason. The madman is the man who has lost everything except his reason” (Lehrer). This is exactly what Lehrer is trying to explain throughout the whole morality chapter, stating that moral decisions are supposed to rely on strictly logical and legal ideas, but these conceptions are based on a vital mistake. Neuroscience has discovered that there is nothing rational about the substrate of moral decisions. When you encounter an ethical problem, the unconscious automatically generates an emotional reaction, and within a few milliseconds, the brain has already made up its mind because you know what is right and what is wrong (Lehrer). These moral instincts are not rational, yet they are essential from keeping people away from committing outrageous offenses. After our emotions have made the moral decision, then the rational circuits in the prefrontal cortex are activated. “People come up with persuasive reasons to justify their moral intuition. When it comes to making ethical decisions, human rationality isn’t a scientist, it’s a lawyer” (Lehrer).
I, probably along with many other people, never knew that morality had a stronger connection with emotions than that of rationality. I never thought about it in the way Lehrer presented it, which has now created my accurate understanding. Moral decisions are all about taking other people’s thoughts or emotions into account. Sadly, psychopaths commit the crimes they do because their emotions never tell them otherwise. Luckily, normal human beings all have this sense of moral distinction built into their brains, and it doesn’t matter what culture you grew up in or what religion you believe in.
In the final chapter, four main ideas are stressed: “novel problems also require reason”, “embrace uncertainty”, “you know more than you know”, and “think about thinking”. Lehrer wraps the book up by stating how amazing the human brain is and how it can always improve itself. “Tomorrow, we can make better decisions” (Lehrer). The first step to doing this is seeing ourselves as we really are, by assessing our flaws and talents, and our strengths and shortcomings (Lehrer). I found this book to be extremely fascinating and helpful, and I enjoyed reading it because I personally happen to be a terrible decision maker. Lehrer continued to suggest throughout his entire book that we need to put the knowledge of our brain to work in order to successfully make decisions, and now I am hoping I can be able to use some of this book and information, to do exactly that.
