Answer: (A)

Hindsight bias is the tendency to see events as having been predictable after they have already occurred. Once the outcome is known, people reinterpret the past as if it were obvious all along, making it feel like the result was inevitable. This helps explain why you might later say you “knew it would happen” even if you wouldn’t have predicted it beforehand. The effect can distort learning from events because it overestimates how well you could have foreseen the outcome, which fuels overconfidence. It’s not about blaming others, ignoring feedback, or confusing correlation with causation; it’s about the after-the-fact sense that the outcome was obvious. To counter it, try documenting your initial hypotheses before outcomes are clear and consciously consider the degree of uncertainty at the time.
