How did you develop a more realistic perspective?
Kathryn Schulz has written a book called Being Wrong, adventures in the margin of error . The book covers many interesting views on wrongness but I'd like to focus here on one. There is a difference between the scientific method and the approach to knowing we as individuals tend to have. Schulz: "The scientific method is essentially a monument to the utility or error. Most of us gravitate toward trying to verify our beliefs ... But scientists gravitate toward falsification.... Not only can any give theory be proven wrong, sooner or later, it probably will be. And when it is, the occasion will mark the success of science, not its failure."
