Why denialism is pernicious

This past weekend, while I was in Scottsdale, AZ, I was able to take some time off and thinking about stuff that I had been mulling over prior to getting to AZ. Most of this stuff has been about the role of science in directing policy-making. However, I realized something: that is wrong with the my thinking about this sort of thing. The thing that was wrong was the impact that out-and-out denialism of scientists and the institutions of science as well. Where did this come from? How did it arise? Why is it effective, and how effective is it? Can/has science denialism affect science-based policy implementation?

Surely part of this comes from a misunderstanding of the nature of what science is. That science has been conflated with some sort of religion has made it into a practice that has been attacked on it's religious grounds - with people saying that since science is a religion, one form or other of it cannot be supported by the state; the separation of church and state argument.

However, even if people don't equate science with religion writ large, the misunderstanding still has had the problem of drawing false equivalences. From the definition of "materialism" to the definition of "theory, law, and hypothesis", and the implication of falsifiability vs. provability, many definitions of terms used among scientists and members of society hold different meanings and implications. Still, the meanings of words matter to understanding, and if people can turn meaning on its head or against its original use, the perceptions done by others of it would be problematic at the minimum and cynical at the maximum.  ... and yet the misinterpretations between scientific and social understanding continues to be expanded, maintained, and [falsely] argued.

Another part of this denialist reaction likely comes from mistrust of scientists. In my mind, some of this mistrust comes from unethical activities that have been publicized in the media. However, why do people just assume that if geneticist Hwan Woo Suk was unethical, all geneticists are unethical? Is it because the work he fabricated results for was related to a series of topics that many people find problematic - stem-cells and (through them) cloning? It's as if the pillorying of this scientist was done because it fit a previously determined narrative in which people who do stem-cell research are unethical, and once one is found, that only proves (falsely) the narrative correct. The same sort of hew-and-cry with the recent "climategate" that erupted with the leaking of e-mails between climate scientists: there is some evidence of climate scientists were trying to hide something, which fits into the theory of some global conspiracy of climate scientists trying to get everyone to emit less carbon (for some strange reason).

Still, if people are mistrusting scientists, using these justifications to deny the science, what are the implications? Well, due to the nature of science -- that it describes and investigates the causes and effects of physical phenomena -- ignoring the results of scientific studies carries implications. Denying the existence of climate change due to a few e-mails is unlike denying the existence of the Easter Bunny due to a classmate saying he doesn't exist are two very different beasts. On the one hand, there is no evidence of the presence or absence of an Easter Bunny, or even the physical, measurable impacts of no Easter Bunny. (In fact, there are many parts of the world in which the Easter Bunny doesn't even exist, or has existed.) However, there are predicted and predicable impacts to natural systems that would come out of a changed climate. These predictable impacts have (slightly less) predictable impacts on biology and (even less) predictable impacts on human society. Would it make sense to act on the possible presence or absence of climate change? Without any evidence, sure. With evidence of only the physical impacts, possibly. With evidence of the physical and biological impacts, quite possibly a good idea. With evidence of the physical, biological, and social impacts, most definitely yes.

And yet... people work at trying to keep the status quo alive and well. People with invested interests. It hurts when your truth gets overturned. It hurt the Catholic Church when Galileo showed that the evidence pointed toward the Earth not being in the center of the Creation. Similarly, it will likely hurt those invested in carbon-based fuels if climate change action is taken, and it is the same in other endeavors, too. Those that have a lot to lose also probably have a lot of incentive to maintain their point of view, and are likely to make efforts to keep their version of reality the only one that is forwarded. Thus, we see lobbying efforts by coal companies against climate change legislation; tobacco companies against tobacco legislation; and health care insurance companies against health insurance legislation.

End result: denialism has consequences on social association with science, with the type of science being done, and with the policy reactions to the scientific (and non-scientific rational) findings that go against certain invested "truths." Eventually, the truth will out. Hopefully, though, it isn't after preventative action can be taken.
