Briefly explain regression to the mean in performance and one common misconception about it.

# Regression to the Mean **What it is:** Regression to the mean occurs when extreme performances are naturally followed by more average ones. If someone has an unusually good (or bad) performance, their next performance will likely be closer to their typical average, simply due to the role of chance in any outcome. **Example:** A salesperson who has their best month ever is likely to have a more modest month afterward—not because they got lazy or lost their edge, but because the exceptional month probably involved some lucky breaks that won't all repeat. ## Common Misconception **The "Hot Hand" or "Slump" Fallacy:** People often create causal explanations for regression to the mean. When a top performer returns to average, we might say they "got complacent" or "lost motivation." When a struggling performer improves, we credit the pep talk we gave them. In reality, these returns to average often happen naturally without any intervention or behavioral change—it's just statistics at work. This leads to falsely crediting (or blaming) interventions, coaching, or personal factors for changes that would have occurred anyway.
