Cognitive Biases, Heuristics, and Thinking Errors in Problem Solving, Belief Formation, and Self-Awareness

Abstract

Human cognition relies on mental shortcuts that allow individuals to make decisions quickly and efficiently. These shortcuts, known as heuristics, simplify complex information processing but may also produce systematic errors referred to as cognitive biases. Cognitive biases influence problem solving, belief formation, judgment, and self-awareness. Although these mental processes can be adaptive by enabling rapid decision making in uncertain environments, they may also distort reasoning and lead to flawed conclusions. This article reviews major cognitive biases and heuristics and examines their role in human thinking, decision-making, and belief formation. It also discusses the implications of these biases for self-awareness and critical thinking. Understanding cognitive biases is essential for improving decision quality in fields such as education, healthcare, research, and policy-making. Strategies for mitigating thinking errors and enhancing reflective thinking are also explored.
