Living a lie: We deceive ourselves to better deceive others

People mislead themselves all day long. We tell ourselves we’re smarter and better looking than our friends, that our political party can do no wrong, that we’re too busy to help a colleague. In 1976, in the foreword to Richard Dawkins’s “The Selfish Gene,” the biologist Robert Trivers floated a novel explanation for such self-serving biases: We dupe ourselves in order to deceive others, creating social advantage. Now after four decades Trivers and his colleagues have published the first research supporting his idea.

Psychologists have identified several ways of fooling ourselves: biased information-gathering, biased reasoning and biased recollections. The new work, forthcoming in the Journal of Economic Psychology, focuses on the first — the way we seek information that supports what we want to believe and avoid that which does not.

Why Facts Don't Change Our Minds

Here is an excerpt:

Stripped of a lot of what might be called cognitive-science-ese, Mercier and Sperber’s argument runs, more or less, as follows: Humans’ biggest advantage over other species is our ability to coöperate. Coöperation is difficult to establish and almost as difficult to sustain. For any individual, freeloading is always the best course of action. Reason developed not to enable us to solve abstract, logical problems or even to help us draw conclusions from unfamiliar data; rather, it developed to resolve the problems posed by living in collaborative groups.

“Reason is an adaptation to the hypersocial niche humans have evolved for themselves,” Mercier and Sperber write. Habits of mind that seem weird or goofy or just plain dumb from an “intellectualist” point of view prove shrewd when seen from a social “interactionist” perspective.

Consider what’s become known as “confirmation bias,” the tendency people have to embrace information that supports their beliefs and reject information that contradicts them. Of the many forms of faulty thinking that have been identified, confirmation bias is among the best catalogued; it’s the subject of entire textbooks’ worth of experiments. One of the most famous of these was conducted, again, at Stanford. For this experiment, researchers rounded up a group of students who had opposing opinions about capital punishment. Half the students were in favor of it and thought that it deterred crime; the other half were against it and thought that it had no effect on crime.

How ‘Intellectual Humility’ Can Make You a Better Person

There’s a well-known Indian parable about six blind men who argue at length about what an elephant feels like. Each has a different idea, and each holds fast to his own view. “It’s like a rope,” says the man who touched the tail. “Oh no, it’s more like the solid branch of a tree,” contends the one who touched the trunk. And so on and so forth, and round and round they go.

The moral of the story: We all have a tendency to overestimate how much we know — which, in turn, means that we often cling stubbornly to our beliefs while tuning out opinions different from our own. We generally believe we’re better or more correct than everyone else, or at least better than most people — a psychological quirk that’s as true for politics and religion as it is for things like fashion and lifestyles. And in a time when it seems like we’re all more convinced than ever of our own rightness, social scientists have begun to look more closely at an antidote: a concept called intellectual humility.

Unlike general humility — which is defined by traits like sincerity, honesty, and unselfishness — intellectual humility has to do with understanding the limits of one’s knowledge. It’s a state of openness to new ideas, a willingness to be receptive to new sources of evidence, and it comes with significant benefits: People with intellectual humility are both better learners and better able to engage in civil discourse. Google’s VP in charge of hiring, Laszlo Bock, has claimed it as one of the top qualities he looks for in a candidate: Without intellectual humility, he has said, “you are unable to learn.”

The Science of Choosing Wisely — Overcoming the Therapeutic Illusion

Here are two excerpts:

The success of such efforts, however, may be limited by the tendency of human beings to overestimate the effects of their actions. Psychologists call this phenomenon, which is based on our tendency to infer causality where none exists, the “illusion of control.” In medicine, it may be called the “therapeutic illusion” (a label first applied in 1978 to “the unjustified enthusiasm for treatment on the part of both patients and doctors”). When physicians believe that their actions or tools are more effective than they actually are, the results can be unnecessary and costly care. Therefore, I think that efforts to promote more rational decision making will need to address this illusion directly.

The outcome of virtually all medical decisions is at least partly outside the physician’s control, and random chance can encourage physicians to embrace mistaken beliefs about causality. For instance, joint lavage is overused for relief of osteoarthritis-related knee pain, despite a recommendation against it from the American Academy of Orthopedic Surgery. Knee pain tends to wax and wane, so many patients report improvement in symptoms after lavage, and it’s natural to conclude that the intervention was effective.
