Why Smart People Make Bad Decisions

Even highly intelligent people make poor decisions.

History is full of brilliant individuals who made costly mistakes—leaders who misjudged risks, investors who ignored warning signs, and professionals who overlooked better opportunities.

Why does this happen?

The answer is that intelligence alone does not guarantee good judgment.

Hidden forces shape our thinking every day. Cognitive biases distort our perception. Incentives influence our behavior. Systems create outcomes that are often difficult to predict. And many decisions involve tradeoffs that people fail to fully consider.

Understanding these forces can dramatically improve how we think and how we make choices.

In Why Smart People Make Bad Decisions, educator and author Kimani Upshur, M.Ed. explains the hidden factors that influence human judgment and decision-making. Using clear explanations and practical examples, this book introduces several powerful ideas from decision science and behavioral economics.

• Why intelligence does not automatically lead to good decisions
• How cognitive biases influence everyday thinking
