Confidence is not evidence about odds
How sure a person feels at the start is an accurate reading of that person and nothing else. Everybody standing in the same line was let in by the same feeling, so the group's rate does not move when one
founder overconfidence
Meaning
Entrepreneurial behavior is often characterized by an inflated belief in one’s own ability to control outcomes. This psychological bias, known as founder overconfidence, leads individuals to underestimate the risks and overestimate the potential returns of their projects. It is the primary reason why so many start-ups are launched in markets that are already saturated.
The bias persists because it provides the emotional drive needed to face high uncertainty.
Cognitive Distortion
Cognitive bias towards exceptional skill is a common feature of those who start new ventures. In the presence of founder overconfidence, a leader is likely to ignore warnings from advisors or market data that contradicts their vision. This bias distorts the evaluation of evidence, leading to a selective focus on positive signals.
It ensures that the founder remains committed to a failing course of action long after the objective data suggests they should pivot or stop.
Financial Risk
The economic cost of this optimism is measured in misallocated capital and lost hours of effort. Because the leader is convinced of their success, they often invest personal funds or secure debt without a realistic plan for repayment. This behavior puts the entire project at risk by ignoring the high probability of failure that characterizes new ventures.
It also reduces the founder’s capacity to build a diverse portfolio, as all their resources are concentrated in a single high-risk asset.
Psychological Defense
Maintaining a high level of optimism is necessary to sustain the daily demands of starting a venture. Without some degree of founder overconfidence, few individuals would choose to enter such a risky field.
