Le Biais du gagnant explique que plus tu gagnes, plus tu augmentes ta Confiance en toi, et plus tu as de chance de gagner encore. C’est une Boucle de rétroaction positive. C’est documenté : gagner augmente ta Testostérone, ta Dopamine, et ta Motivation.
The “winner effect” is a biological phenomenon where an animal that wins a fight becomes more likely to win future contests, and it also applies to humans. Success causes physical and chemical changes in the brain, such as increased levels of hormones like testosterone and dopamine, which boost confidence, focus, and motivation. This creates a self-reinforcing cycle where early wins can lead to more wins, while the “loser effect” can cause the opposite, making it harder to succeed after a string of losses
