How Scientific Consensus Has Gotten a Bad Reputation

nerdyalien writes From the article: "Fiction author Michael Crichton probably started the backlash against the idea of consensus in science. Crichton was rather notable for doubting the conclusions of climate scientists—he wrote an entire book in which they were the villains—so it's fair to say he wasn't thrilled when the field reached a consensus. Still, it's worth looking at what he said, if only because it's so painfully misguided: 'Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results.'" As a STEM major, I am somewhat biased toward "strong" evidence side of the argument. However, the more I read literature from other, somewhat-related fields (i.e. psychology, economics and climate science), the more I felt they have little opportunity to repeat experiments, similar to counterparts in traditional hard science fields. Their accepted theories are based on limited historical occurrences and consensus among the scholars. Given the situation, it's important to understand what "consensus" really means.

    Please stop. You think you know what you are talking about but you really don't. If you understand anything about experimental design and statistical analysis you would not have written the second sentence. Correlation or causation depends on the design of the study. When it comes to surveys, those would be correlational studies. When it comes to studying animal behavior, those would be causation.

    Any study's results are only generalizable to the population from which the sample was derived. Thus if the sample was taken from a population of Ohio State university students, those results are only generalizable to that population. Your complaint is with the media and how they report the results no the study's principle investigator.

    A consensus is a bunch of people who share an opinion. It has nothing to do with right or wrong.

    In economics, the Austrian School folks agree with you so strongly that they reject the notion that empirical data can trump a priori reasoning. Recognizing that there is no "controlled experiment", any data that refutes a well-reasoned logical argument is considered incomplete. It's a remarkable rejection of empiricism and a recognition that economic activity is based on human behavior (praxeology) and as such can't be precisely quantified.

    It is proper English. It is the difference between the active and passive voice. "He was sick, but he got well." "He was sick, but he has gotten well." The difference is actually tangentially related to the story subject. When I was in university [mumble] decades ago, all scientific papers for publication, and by extension all term papers, were required to be written in the third person past passive voice. This was thought to appear more objective. Printing costs for scientific journals drove the change to active voice, because, in English, that voice uses fewer words. Now that journals are largely electronic, printing costs are less of an issue, leaving aside Dilbert's PHB's concern about using up electrons. Active voice may also be more readable, particularly for those being taught by teachers who say things like, "Me and him went to the store."

    Passive voice example should have been, "He has been sick, but he has gotten well."

    AAAAArg. This is NOT passive voice!! Does really nobody have the fainstest idea of grammar anymore?
