Fringe ideas often get a poor reception from mainstream scientists, but can still appeal to the public and influence policy debates. Some recent examples of papers that delve into the fringes of science provide a nice example of why not all fringe ideas are created equal.

The history of science is replete with examples, from plate tectonics to prions, of heretical ideas that received a poor reception from the scientific establishment when they were first proposed. The apparent resistance to new ideas has earned scientists a fair bit of criticism. But some recent publications have indicated both that it is possible for fringe ideas to get a hearing from mainstream science, and that their proponents may end up wishing they didn't.
Fringe ideas that go against mainstream scientific thought are effectively a constant in most areas of science, and there are a number of examples where the ideas have moved from the fringes to the mainstream. The classic example here is Alfred Wegener, who is celebrated for his development of the ideas we now know as plate tectonics, a phenomenally successful scientific theory. At the time, however, his ideas were ridiculed. "Reaction to Wegener's theory was almost uniformly hostile, and often exceptionally harsh and scathing," as the Berkeley site notes.
Many have used that as a cautionary tale, a warning that the conservatism of the scientific community might interfere with achieving its goal of understanding the natural world. But, as we noted, fringe ideas, often dozens of them for every successful area of science, are a constant. Inevitably, the majority of them will necessarily wind up being not only wrong, but uselessly so. This forces the scientific community into a balancing act; in the words of Richard Feynman, scientists have to "Keep an open mind, but not so open that your brain falls out."
