“The only way to have real success in science, the field I’m familiar with, is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory, you must try to explain what’s good and what’s bad about it equally. In science, you learn a kind of standard integrity and honesty.
“In other fields, such as business, it’s different. For example, almost every advertisement you see is obviously designed, in some way or another, to fool the customer: the print that they don’t want you to read is small; the statements are written in an obscure way. It is obvious to anybody that the product is not being present in a scientific and balanced way. Therefore, in the selling business, there’s a lack of integrity.
“My father had the spirit and integrity of a scientist, but he was a salesman. I remember asking him the question, ‘How can a man of integrity be a salesman?’
“He said to me, ‘Frankly, many salesman in the business are not straightforward–they think it’s a better way to sell. But I’ve tried being straightforward, and I find it has its advantages. In fact, I wouldn’t do it any other way. If the customer thinks at all, he’ll realize he has had some bad experience with another salesman, but hasn’t had that kind of experience with you. So in the end, several customers will stay with you for a long time and appreciate it.”
