For example, if a student needed to decide what subject she will study at university, her intuition will likely be drawn toward the path that she envisions most satisfying, practical and interesting.
What is heuristic and bias?
Think of heuristics like guidelines, or rules of thumb: they’re usually good enough most of the time, but they can result in errors. Cognitive biases are systematic errors in thinking that interfere with how we reason, process information, and perceive reality.
