Yes, the key issue is not so much whether on a first analysis you came to think those other folks are not as well informed as you, but whether you would have thought that if you had been taught by them. The issue is how to overcome the numerous easy habits of assuming that what you were taught must have been better. Once you see that on a simple first analysis you would each think the other less informed, you must realize that the problem is harder than you had realized and you need to re-evaluate your reasons for so easily thinking they are wrong and you are right. Until you can find a style of analysis that would have convinced you, had you grown up among them, to convert to this side, it is hard to believe you've overcome this bias.
