Inquiring doubt uses mindfulness for investigation. Mindfulness practice helps overcome doubt because it acts with the confidence that it is possible “to know,” or be mindful of how things are in any given moment. Or if you encounter a situation where all you know is confusion, then with mindfulness at least you have the clarity to know that you do not know. This distinction between knowing and knowing you do not know is surprisingly grounding and can stop doubt from working its way into your nervous system.

This insight leads to the first step in working with doubt: cultivating “don’t know mind,” which dispels the myth that you are always supposed to know, never to be in doubt. Likewise, you can examine your mind to see if you have an expectation that you should be perfect, which prevents you from realizing that painful mistakes are part of living life. New knowledge creates new uncertainties, so that which is causing you doubt can be appreciated because it signifies new possibilities to learn about yourself.

From The Checklist Manifesto  by Atul Gawande:

We don’t like checklists. They can be painstaking. They’re not much fun. But I don’t think the issue here is mere laziness. There’s something deeper, more visceral going on when people walk away not only from saving lives but from making money. It somehow feels beneath us to use a checklist, an embarrassment. It runs counter to deeply held beliefs about how the truly great among us–those we aspire to be–handle situations of high stakes and complexity. The truly great are daring. They improvise. They do not have protocols and checklists.

Maybe our idea of heroism needs updating.
