Problem Solving: Algorithms vs. Heuristics
In this video I explain the difference between an algorithm and a heuristic and provide an example demonstrating why we tend to use heuristics when solving problems. While algorithms provide step-by-step procedures that can guarantee solutions, heuristics are faster and … Read More
Obstacles to Problem Solving
In this video I introduce several potential obstacles to problem-solving including overconfidence, illusory superiority, belief bias, and belief perseverance. Then I describe a “consider the opposite” strategy for potentially reducing the influence of bias when interpreting evidence that supports or … Read More
Problem Solving
In this video I introduce several concepts related to problem-solving. I begin with mental set, which refers to our tendency to rely on approaches that have worked in the past. Similarly, functional fixedness refers to our tendency to think of … Read More
