There are things (think of Higgs boson type) that lie on the limit of observability/detection, for which there isn't any guarantee that there will ever be means strong enough to qualify for the same level of rigorous study as most of the scientists are comfortable with. The easiest thing to do is to draw a line and to dismiss everything that goes beyond it. The smarter thing to do (in my view) is to recognize the decrease of control and accuracy in our means and classify the fields of study accordingly, then both asking and granting different levels of trust to what is being studied.
