"Mistakes can be corrected by those who pay attention to facts but dogmatism will not be corrected by those who are wedded to a vision"

This quote by Thomas Sowell talks to the value of being open to facts and evidence when making choices. He suggests that mistakes can be fixed if we pay attention to realities, but dogmatism can not be corrected if we are too attached to a specific vision. This suggests that we must be willing to change our views and viewpoints if the realities and evidence suggest that we should. It also suggests that we should be open to various viewpoints and concepts, and not be too connected to our own vision. By being open to truths and evidence, we can make much better decisions and avoid making errors. Dogmatism, on the other hand, can result in stubbornness and a refusal to accept new ideas, which can cause errors that are difficult to fix.
