Think Again: The Courage to Rethink | Wang Kevin | TEDxNACIS Shanghai Youth

We live in a world that rewards certainty, admiring confident leaders and experts with all the answers. However, we are rarely taught to rethink our beliefs. This presentation advocates for a reflective and open-minded hesitation, challenging the shame associated with asking "What if I'm wrong?" Our brains are wired to see beliefs as part of our identity, making an attack on a belief feel like a personal attack. This leads us to surround ourselves with information that confirms our existing views, a phenomenon known as confirmation bias. The world is not static; what was true yesterday might not be true today. Progress often involves redrawing old maps, not just navigating them. This is the difference between conviction, which states "this is the way," and reflection, which asks "what are the other ways?" To become thoughtful rethinkers, we should first separate our convictions from our opinions, saying "I believe this for now" instead of "this is who I am." Opportunities arise from extensive and multiple ideas. Second, we should actively seek out disagreeable evidence, reading articles from other perspectives and listening to those who see the world differently, not to refute them but to understand. This deepens our understanding. Thirdly, we should normalize saying "I used to believe, but now I say," proudly acknowledging our growth. The goal is not to get it right at once, but to get it right throughout our lives, which requires constant revision. The most dangerous people are not those who don't know, but those who are certain they do and stick to the simplest ideas. We should admire the flexibility of a reed over the brutal strength of an oak in a storm. Let's build our identities on being engaged, open-minded, reflective, and willing to see the world from new perspectives.
