The Winner Effect explains a powerful scientific idea:

Winning changes the brain in ways that make future winning more likely.

When a person wins:

• 🧪 Dopamine increases → motivation rises

• 💪 Testosterone increases → confidence and competitiveness increase

• 😌 Stress hormones decrease

Because of these biological changes, winners often develop a cycle of success.

Win → Brain chemicals rise → Confidence increases → More risk-taking → Higher chance of winning again

This phenomenon is called The Winner Effect.
