The Self-Competition thinking model originates from the "Left-Right Combat Technique" in Jin Yong's martial arts novels. Its essence lies in examining the same issue from two opposing perspectives simultaneously. It encourages self-debate and self-challenge—akin to having two internal voices that inspire each other—thereby breaking through the limitations of conventional thinking, revealing richer and more comprehensive insights, and enabling more rational and accurate decision-making. This mode of thinking helps avoid "confirmation bias" and escape "fixed mindsets," enhancing cognitive abilities.
