When we learn something new, we don't go from being “wrong” to “right.” We go from wrong to slightly less wrong. There is never any “right” answer but we can try to get as close as we can. Being wrong opens up possibilities for change and growth.
The human brain is imperfect. Most of what we “know” is convoluted by the inaccuracies and biases in our brains. Therefore, whether you believe it or not, most of our beliefs are wrong.
The more you embrace being uncertain and not knowing, the more comfortable you will feel in knowing what you don't know. Uncertainty is the root of all progress and growth. The more we admit we don't know, the more we can learn.
It is difficult to question and doubt our thoughts and beliefs. These questions can help: 1) What if I'm wrong? 2) What would it mean if I were wrong? 3) Would being wrong create a better or a worse problem than my current problem, for both myself and others?
