Why smart people defend bad ideas

By Scott Berkun, April 2005

We all know someone who’s intelligent, but who occasionally defends obviously bad ideas. Why does this happen? How can smart people take up positions that defy any reasonable logic? Having spent many years working with smart people I’ve cataloged many of the ways this happens, and I have advice on what to do about it. I feel qualified to write this essay as I’m a recovering smart person myself and I’ve defended several very bad ideas. So if nothing else this essay serves as a kind of personal therapy session. However, I fully suspect you’ll get more than just entertainment value (“Look, Scott is more stupid than we thought!”) out of what I have to say on this topic.

Success at defending bad ideas

I’m not proud to admit that I have a degree in Logic and Computation from Carnegie Mellon University. Majoring in logic is not the kind of thing that makes people want to talk to you at parties, or read your essays. But one thing I did learn after years of studying advanced logic theory is that proficiency in argument can easily be used to overpower others, even when you are dead wrong. If you learn a few tricks of logic and debate, you can refute the obvious, and defend the ridiculous. If the people you’re arguing with aren’t as comfortable in the tactics of argument, or aren’t as arrogant as you are, they may even give in and agree with you.

The problem with smart people is that they like to be right and sometimes will defend ideas to the death rather than admit they’re wrong. This is bad. Worse, if they got away with it when they were young (say, because they were smarter than their parents, their friends, and their parent’s friends) they’ve probably built an ego around being right, and will therefore defend their perfect record of invented righteousness to the death. Smart people often fall into the trap of preferring to be right even if it’s based in delusion, or results in them, or their loved ones, becoming miserable. (Somewhere in your town there is a row of graves at the cemetery, called smartypants lane, filled with people who were buried at poorly attended funerals, whose headstones say “Well, at least I was right.”)

Until they come face to face with someone who is tenacious enough to dissect their logic, and resilient enough to endure the thinly veiled intellectual abuse they dish out during debate (e.g. “You don’t really think that do you?”or “Well if you knew the <insert obscure reference here> rule/law/corollary you wouldn’t say such things”), they’re never forced to question their ability to defend bad ideas. Opportunities for this are rare: a new boss, a new co-worker, a new spouse. But if their obsessiveness about being right is strong enough, they’ll reject those people out of hand before they question their own biases and self-manipulations. It can be easier for smart people who have a habit of defending bad ideas to change jobs, spouses, or cities rather than honestly examine what is at the core of their psyche (and often, their misery).

Short of obtaining a degree in logic, or studying the nuances of debate, remember this one simple rule for defusing those who are skilled at defending bad ideas: Simply because they cannot be proven wrong, does not make them right. Most of the tricks of logic and debate refute questions and attacks, but fail to establish any true justification for a given idea.

For example, just because you can’t prove that I’m not the king of France reincarnated doesn’t make it so. So when someone tells you “My plan A is the best because no one has explained how it will fail” know that there is a logical gap in this argument. Simply because no one has described how it will fail, doesn’t necessarily make it the best plan. It’s possible than plans B, C, D and E all have the same quality, or that the reason no one has described how A will fail is that no one has had more than 30 seconds to scrutinize the plan. As we’ll discuss later, diffusing bad thinking requires someone (probably you) to construct a healthier framework around the bad thinking that shows it for what it is.
