Lack of humility in the sciences

How can any scientific enquiry not allow for the possibility that its own worldview might be incorrect?

If it is replied that certain types of argument and enquiry would cut of the branch on which the worldview was sitting, the counter-reply might be that, if that is where the argument leads, you had better find yourself another branch, or even another tree.
