The Green Lumber Fallacy is a cognitive bias that occurs when individuals mistakenly believe they understand the key factors of a concept or industry, while in reality, their knowledge is based on irrelevant or superficial details.

• Academic knowledge does not automatically mean practical wisdom in real life situations
• One doesn’t need to know everything about how something works to be able to use it, or more appropriately, to benefit from it. For example, you need not be aware of the history of an internal combustion engine to learn driving.
• Knowledge is helpful, but there’s a stark difference between, what Aristotle calls practical wisdom (phronesis) and scientific knowledge (epistēmē).
• Birds learn to fly by doing, by trial and error. They do not go to flight school and listen to theories on aerodynamics.

Any fool can know. The point is to understand. — Albert Einstein
