This couldn’t be further from reality. I often tell people that the difference between a scientist and the average person is that a scientist is more aware of what he/she doesn’t know about their specific field, whereas the average person doesn’t know what they don’t know. In other words, everyone suffers from crushing ignorance, but scientists are (one hopes) usually more aware of the depth of theirs. They might occasionally have an idea about how to slightly increase a particular body of knowledge, and sometimes that idea might even prove successful. But for the most part they spend their time thinking about a deep chasm of knowledge specific to their field.
This is the best thing I have read today!
