The Paradox of Confidence
by Rick Brenner
Most of us interpret a confident manner as evidence of competence, and a hesitant manner as evidence of lesser ability. Recent research suggests that confidence and competence are inversely correlated. If so, our assessments of credibility and competence are thrown into question.
In this culture, and others, we value confidence in leaders, mechanics, doctors, generals, and even strangers we've asked for directions. But in all these cases, and more, we're actually seeking expertise, knowledge, and capability — in short, competence.
U.S. Secretary of the Treasury Robert Rubin (left) with Federal Reserve Board Chairman Alan Greenspan in discussion before meeting with the House Banking Committee on 20 May 1999, just six months before the work of Kruger and Dunning appeared. They were then both at the height of their power, which both used liberally to resist calls for regulation of new and growing sectors of the financial markets — the very sectors that contributed so much to the financial crisis at the end of 2008. Both men were studies in confidence, and that confidence played a role in persuading officials and the population at large that the U.S. economy was healthy and on course. Yet, on 23 October 2008, under questioning by Rep. Henry Waxman, chair of the Committee on Oversight and Government Reform of the U.S. House of Representatives, former Chairman Greenspan testified, with regard to his "conceptual framework with the way people deal with reality," that, "…I found a flaw, I don't know how significant or permanent it is, but I have been very distressed by that fact." He went on, "I found a flaw in the model that I perceived is the critical functioning structure that defines how the world works…I was shocked." One model of what might have happened to him is that he had discovered the limits of his competence. The fourth factor observed by Dunning and Kruger states that, "Incompetent individuals can gain insight about their shortcomings, but this comes (paradoxically) by gaining competence." If this model applies, one might conclude that by October, 2008, Mr. Greenspan was somewhat more competent than he had been in 1999.

We usually assume that confidence comes from competence. We apply this assumption personally when we seek health care, investment advice or other services. But we also apply it at work — when we make hiring decisions, when we evaluate the assertions of superiors and subordinates, and when we get advice from consultants.
Trouble is, the assumption is wrong.
We know this because of the pioneering work of Justin Kruger and David Dunning, who, working at Cornell in 1999, discovered a phenomenon now called the Dunning-Kruger effect. They performed experiments that yielded results consistent with these four principles (paraphrasing):
- Incompetent individuals, compared with their more competent peers, dramatically overestimate their ability and performance.
- Incompetent individuals are less able than their more competent peers to recognize competence when they see it.
- Incompetent individuals are less able than their more competent peers to gain insight into their true level of performance.
- Incompetent individuals can gain insight about their shortcomings, but this comes (paradoxically) by gaining competence.
Taken together, these four factors contribute to an inverse correlation between confidence and competence — exactly the opposite of what most of us assume.
If we can't rely on confidence as an indicator of competence, on what can we rely? In assessing competence, when we do consider factors beyond confidence, we tend to focus on domain-specific content. That helps, but it's not enough. Here are four generic indicators of competence for application in the workplace.
- Awareness of limitations
- The truly competent understand that their competence is limited — that there are things they can't do or don't know. This knowledge drives a continued desire to learn.
- Desire to learn
- Curiosity, practice, questioning, and continued study are signs of a drive to enhance competence. It is this drive that established the existing level of competence. Where this drive is weak, competence is questionable.
- Constructive response to failure
- Responding to Incompetent individuals, compared
with their more competent peers,
dramatically overestimate their
ability and performancefailure in constructive ways is another important way to build competence. This ability is probably essential to building competence.
- Ability to assess risk realistically
- Realistic risk assessment requires a reservoir of experience — competence — in the relevant domains. Incompetence leads to mis-assessment of risk. The fearful and incompetent tend to overestimate risks; the brash and incompetent tend to underestimate them. Competence tempers both.
I'm not 100% sure that these indicators are necessary and sufficient — probably not. But they've come to me through a lifetime of experience. If you have others you rely on, send them to me and I'll consider adding them to my list. Top Next Issue

- The Race to the South Pole: Lessons in Risk Management for Leaders
- On 14 December 1911, four men led by Roald Amundsen reached the South Pole. Thirty-five days later, Robert F. Scott and four others followed. Amundsen had won the race to the pole. Amundsen's party returned to base on 26 January 1912. Scott's party perished. As historical drama, why this happened is interesting enough. But to organizational leaders and project managers, the story is fascinating. We'll use the history of this event to explore lessons in risk management and its application to organizational efforts. A fascinating and refreshing look at risk management from the vantage point of history. Read more about this program. Here's an upcoming date for this program:
- Cognitive Biases and Workplace Decision-Making
- For most of us, making decisions is a large part of what we do at work. And we tend to believe that we make our decisions rationally, except possibly when stressed or hurried. That is a mistaken belief — very few of our decisions are purely rational. In this eye-opening yet entertaining program, Rick Brenner guides you through the fascinating world of cognitive biases, and he'll give concrete tips to help you control the influence of cognitive biases.

- The Politics of Meetings for People Who Hate Politics
- There's a lot more to running an effective meeting than having the right room, the right equipment, and the right people. With meetings, the whole really is more than the sum of its parts. How the parts interact with each other and with external elements is as important as the parts themselves. And those interactions are the essence of politics for meetings. This program explores techniques for leading meetings that are based on understanding political interactions, and using that knowledge effectively to meet organizational goals.
