The document discusses cognitive biases that cause people to cling to their own models and perspectives even when evidence shows they are wrong. It notes that government economists often choose models that support their own careers rather than accurately describe the economy. In contrast, scientists like Einstein were willing to discard incorrect models as soon as evidence proved them wrong. The document advocates listening to other people's perspectives to understand their "models of the world" and be able to communicate your own ideas in a way that fits within their frameworks to gain more agreement.
