It’s very important to be able to be wrong. That is, you want to be able to stand up against criticism, or people who differ with you. You want to be able to take chances. You also want to be able to recognize when you’re wrong. And you’re going to be wrong some of the time, and it doesn’t hurt a scientist to be wrong, especially if he can recognize it. If he recognizes it first, that’s great. If somebody else recognizes he’s wrong and proves it to him, well then okay, you accept that. Yes, I was wrong. And so you go on and do something else. It’s the sorting out of what’s right and what isn’t right, we do it all the time. And sure, we’re wrong some of the time and we’re right some of the time. But the fact that we can sort that out and decide is what’s great about science. So you can continue to build on what is right, and when that’s tested by other people, you may have to stand up against the community for some time, but eventually, other people will be able to decide whether you’re right or wrong. Doing experiments and showing it, for one thing. Or doing the experiment and finding out it doesn’t work. Then you know. You don’t want to waste too much time on being wrong, you want to say, “Well all right, I was wrong, and what did I learn from that?” And go on and find a better way of doing things.
