Q. If one declares oneself to be a volunteer, must one not weigh the advantages against the disadvantages?
A. I believe so.
Q. The disadvantage here is the risk of a serious disease, the advantage is fifty or a hundred dollars.
A. I should say the advantage is being able to serve for the good of humanity.
Q. For what reason was the money not paid immediately, but in two payments? So far as I remember from a document yesterday, the hundred dollars was paid as follows: fifty dollars after the first month, and the other fifty after one year. In other words, a prisoner has to do his job first. Now, why was that so?
A. I presume that that is just the common way of doing business in the United States when an agreement is involved. I presume the lawyers had something to do with that.
Q. Was the reason not this: that the prisoner would lose his enthusiasm for the experiment and would cease to cooperate? Could that have been the reason for being a little circumspect in the payment?
A. I doubt that.
Q. Do you know of a case where the experimental subject did not wish to continue the experiment?
A. That has not been my experience. And according to the response that I got to that question when I put it to Dr. Irving, he said that no one expressed a desire to withdraw at any time.
