Not consciously. But being wrong and saying oops may have helped me take that lesson to heart:

When I was very young, I thought that the ingredients section of a food label had to list, as the first ingredient, something that comprised over 50% of the product. If I still believed this, it would be easy to prove to me that a five-bean salad was mostly kidney beans. Simply show that none of the other four bean types made up a majority of the salad, and there you'd have it!
