" The mind’s tendency to hold on to what is familiar is enhanced by the fact that the overall tacit infrastructure is inseparably woven into the whole fabric of science as well as into its institutions, on which depends the professional security of each scientist. As a result, there is always a strong pressure against any individual scientist who threatens to “rock the boat.” But of course, this resistance is not confined simply to science but occurs in every walk of life when familiar and comfortable thoughts and feelings are threatened. People will therefore tend not to have the necessary energy and courage to call into question the whole tacit infrastructure of their field. But this becomes increasingly difficult to do as the whole infrastructure ultimately extends, in its implications, into the whole of science and even of society itself. "
