GEOFFREY LLOYD: I think a number of things. First of all, one could ensure that the person making the statement, by virtue of his background, training and education, had received an education that would allow him to make that judgement. As a practising physician I see examples, and I will if it’s appropriate cite specific examples, where the person making statements is either not aware of the literature or, alternatively, by virtue of his background training and education, has not received the training. As a physician, for example, it is mandated by the college that I must know prognosis in my area of discipline.
