Misleading Vividness

Rhetorical fallacies are often defined as errors in reasoning. Most of them actually are errors of reasoning. Members of that class are easily recognized once we understand them. But rhetorical fallacies that exploit flaws in the human ability to reason often escape detection even after we know how they work. The fallacy known as Misleading Vividness is one of these.

Here's an example: "I wouldn't take a customer to lunch there if I were you. Remember when Grant was hospitalized? I heard that he got sick from the sour cream on their baked potatoes."

Admittedly this "argument" contains errors of reasoning, but its power comes from its vividness: we know that restaurant, we know Grant, we've been to hospitals, and we know the taste of baked potatoes and sour cream. Grant's co-workers can easily imagine the scene.

We humans evaluate the soundness of arguments, in part, in terms of the ease of imagining their elements. If the elements are especially vivid, we're more likely to process the argument heuristically, rather than systematically or analytically. When we do, logical errors are more likely.

When we think, we usually use both heuristics and logic, with each process influencing the other. Those who employ the misleading vividness rhetorical fallacy are often trying to tilt us toward heuristics, away from reason. When they succeed, we're more likely to accept unproven conclusions.

This phenomenon explains, in part, why advertisers use celebrity endorsers. They're trying to trigger heuristic thinking by relying on the good feelings we have for the celebrities. It also explains why politicians so often employ scare tactics. They conjure vivid, scary images that cause some of us to think more heuristically.

When we make decisions at work, we have to be more careful. Here are three indicators of the use of misleading vividness in workplace debate.

Sensory breadth

Messages that invoke more senses are experienced as being more vivid. The more direct the invocation, the more vivid the message. The story about the baked potato would have greater impact when told while baked potatoes were being served.

their elementsmight be necessary as part of a discussion about, say, a dinner menu while planning a conference. Sensory breadth that isn't required as part of the task at hand could indicate the use of misleading vividness.

Overly detailed examples

Although counterexamples can disprove general claims, examples rarely prove claims. They're useful illustrations — nothing more.

When examples offered as illustration contain powerful imagery that can invoke strong emotions, they could be instances of misleading vividness.

Personal stories

Clarifying stories can be helpful. When stories are personal, first person or not, they can evoke strong feelings.

Personal stories that evoke emotions are especially vivid. When listeners relive the experience of the story, or similar experiences, misleading vividness is a strong possibility.

The Perils of Piecemeal Analysis: Group Dynamics

When a team relies on group discussion alone to evaluate proposals for the latest show-stopping near-disaster, it exposes itself to the risk that perfectly sound proposals might be inappropriately rejected. The source of some of this risk is the nature of group discussion.

Finding the Third Way

When a team is divided, and agreement seems out of reach, attempts to resolve the conflict usually focus on the differences between the contrasting positions. Focusing instead on their similarities can be a productive technique for reaching agreement.

The Power Affect: How We Express Our Personal Power

Many people who possess real organizational power have a characteristic demeanor. It's the way they project their presence. I call this the power affect. Some people — call them power pretenders — adopt the power affect well before they attain significant organizational power. Unfortunately for their colleagues, and for their organizations, power pretenders can attain organizational power out of proportion to their merit or abilities. Understanding the power affect is therefore important for anyone who aims to attain power, or anyone who works with power pretenders. Read more about this program.

Bullet Points: Mastery or Madness?

Decision-makers in modern organizations commonly demand briefings in the form of bullet points or a series of series of bullet points.
