If funding is on the line, scientists are pretty hesitant to abandon their errors. Plus, the statement shows a remarkable ignorance about philosophy of science and how scientists actually operate. I mean as one small example, take Kuhn. A large part of his argument hinges on the argument that scientists are NOT likely to abandon their errors.
I suggest to you that the important thing is not whether an individual scientist 'abandons his errors'. Science is not just something that happens in a scientist's head.
The point is rather that science is a large, diffuse and evolving social institution, that has demonstrated repeatedly that it does succeed in abandoning things shown not to work, and embracing those that do. It thrives on new questions, and rewards those who ask fruitful ones. Those who can succeed in persuading the majority of scientists to abandon an old idea and adopt a new one are richly rewarded in terms of reputation.
Such an institution is very different indeed from an institution such as a religion, most of whose effort is often spent in discouraging the asking of awkward questions and defending the old answers against all attacks from wherever they come.
