Who does more damage, A) mean-spirited people or B) “normal” people acting thoughtlessly? According to Hannah Arendt, the answer is clearly B. I would agree. Why? Because we serve as our own gate-keeper as to what what aspects of the world are relevant but our “gate-keeper” is a sycophantic enabler of our deepest darkest instincts.
How is it that “normal” people so often behave (and vote) as moral monsters? In Eichmann in Jerusalem (discussed below), Arendt has written about the “banality of evil,” that the failure to think leads to monstrous deeds–the road to hell is mostly paved with no intentions or serious thoughts. I largely concur with Arendt, but I would explain the source of most evil in terms of the psychological concept of attention: human animals have limited attentional capacities and ghastly things happen when this scarce human resource is diverted (often self-diverted). Moral monsters self-train themselves to pre-filter their sensory perceptions so that they don’t have to attend to anything that challenges their preferred viewpoints.
The trick to becoming a banally evil person is to allow yourself to dwell on limited viewpoints and experience. To grow your evilness, stop being self-critical, stop being skeptical and stop exposing yourself to viewpoints other than your own. When you do these things for awhile, you’ll become a God in your own eyes and you’ll become comfortable trying to burn your narrow intellect onto everything and everyone you encounter.
It takes courage to expose one’s self to information that challenges one’s pre-existing beliefs. Humans are often self-manipulative. Many (most?) of us sub-consciously (or semi-consciously) expose ourselves mainly to the types of information that will substantiate our preconceived notions and motives. We’ve all seen this with the many dysfunctional people who use the Internet selectively. They seek out only web sites that are compatible with their pre-existing bigoted, consumerist or shallow life-styles.
If you put on blinders that allow you to see only a limited slice of the world around you, you can spare yourself the need of emotionally reacting to desperate needs of humans around you. Most of us constantly blind ourselves to the plight of starving children in Africa. Out of sight, out of mind. It’s merely a matter of diverting our attention to something else, something not disturbing.
Many of the horrible things people do are not done with their full range of attention on the ramifications of their actions. Soldiers couldn’t effectively kill if they took the time to consider that the guy whose image is in the rifle scope is often a father of small children with much the same dreams and hopes as the soldier. Soldiers are trained to see those they are fighting in dehumanized ways as “the enemy” and “insurgents” or in racially or ethnically derogatory ways. This is another example of diverted attention. When we stop thinking about bothersome things, they cease to bother us!
What makes us who we are is not “the world,” as much as the habits we employ to filter the world. We filter the world by pointing the spotlight of attention. We often choose to look away from things that annoy or outrage us. Then, we often choose to not think about the fact that we trained ourselves to look away. We cease to think about our option to think about certain things.
We are able to do many of the horrible things we do because we choose to not look, not listen, not consider, not to empathize. Humans are marvelously able to not attend to inconvenient aspects of their world. This skilled use of blinders enables many of us to blithely announce how “life is so incredibly good” when thousands of people all around us are desperately ill, hungry, trapped in horrible schools and financially-desperate.
Here’s an example currently in the news. In my opinion, many of the people who vehemently oppose stem-cell research refuse to empathize with desperately ill people who might someday be helped by treatments developed using stem cell research. Most opponents of stem cell research act like it’s not a legitimate issue to discuss the plight of people fighting horrible illness: that they are in great pain, scared, feeling hopeless and desperately wanting to live normal lives. How can anyone possibly refuse to let research proceed to help such desperate people? By refusing look them in the eyes and see them fully as human beings. By treating them the same way that the soldier treats the guy he sees through the rifle scope. By attending exclusively to the notion that un-implanted clumps of 150-stem cells containing no nerve cells are the moral equivalents of “babies.”
Our capacity to manipulate the spotlight of attention can turn dying people into pre-dead people and it can turn clumps of un-implanted stem cells into cooing “babies.” After all, we are a superbly symbolic species. By tweaking attention, we can turn anything into anything. Our symbolic capacity is humankind’s ultimate two-edged sword.
If misused, the capacity to manipulate the “spotlight” of human attention thus constitutes a dangerous weapon. It is so dangerous, that studying the limitations of human attention should be a required topic in any discussion of morality. This brings to mind the challenge of Eleanor Rosch that “with the exception of a few largely academic discussions cognitive science has had virtually nothing to say about what it means to be human in everyday, lived situations.” Her challenge continues (p. xx): “The issues at hand, though scientific and technical, are inseparable from deeply ethical concerns, ones that require an equally deep re-understanding of the dignity of human life.” [See The Embodied Mind, F. Varela, E. Thompson and E. Rosch, p. xv (1992).]
Back to the capacity of human attention, though. That it is severely limited is supported by a massive scientific literature. Here’s one place to start. Huge bottlenecks thus exist at the point where we perceive the world. We miss a LOT. The world is laughingly beyond our capacity to absorb without drastic simplification, and we are certainly good at simplifying it. David van Essen, (Department of Anatomy and Neurobiology, Washington University) has presented the dramatic loss of information from perception to long-term memory as an inverted pyramid:
- We start with the World of information, which is unlimited.
- 1010 bits/second of information = capacity of retina
- 107 bits/second of information = capacity of optic nerve
- 104 bits/second of information = capacity of attention
- 10 bits/second of information = capacity of long term memory
["Translating the neural code: neurons as detectives, not detectors," Intentionality and the Natural Mind Workshop, March 19, 1999.]
We thus perceive only a small slice of the available world and we remember only a tiny portion of the world that we successfully perceive. Yet perception seems so very full and complete. For a demonstration of our perceptual limitations, try watching a short (about 30 seconds) video – your job is to very carefully count the number of times that any student passes a ball to any other student. You saw it all, right? Then watch the short video again without counting the passes. Here’s the video. This demo “works” on about 50% of the people who watch it, in my experience. If it “works,” you’ll be amazed.
Working memory is another attentional bottleneck. As George Miller pointed out long ago, “[T]he span of absolute judgment and the span of immediate memory impose severe limitations on the amount of information that we are able to receive, process and remember.” [George A. Miller, “The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information,” The Psychological Review, Vol. 63, No. 2 (March, 1956)].
To summarize: We are not capable of perceiving much of what goes on around us. We are incapable of considering many things we do perceive, because working memory is so incredibly limited. Yet we don’t feel limited. Our cognitive capacity smoothes over most of our perceptual and cognitive gaps. We are impatient and we often get fatigued. Thus we are quite willing to confidently forge ahead based on less than a complete record. Those of us who do rein in our impatience with skeptical inquiry and the scientific method tend to oversimplify our world in a way that justifies anything at all.
The resulting illusion of omniscience combines with ubiquitous fatigue, enticing humans to make wild cognitive leaps in order to just get on to the next thing. We are thus fearless in our ignorance. Humans are experts at feeling confident even when they make decisions based on woefully insufficient information.
Add one more thing to the mix: “toxic thoughts.” Humans are highly skilled at suppressing inconvenient or dangerous thoughts. Many believers simply can’t consider whether it’s possible that God doesn’t exist. Many humans choose to expose themselves only to information that will reinforce pre-existing beliefs. That a 150-cell clump of cells lacking any nerve cells doesn’t think is a “toxic thought” to opponents of stem cell research. That humans are animals is a toxic thought to many people who oppose evolution.
Really, truly, the failure to be aware of the limited character of human attention can be dangerous. Here’s how dangerous it can be. (more…)
