Scientific Ignorance

Ben Goldacre complains about media coverage of science, and also complains about humanities graduates:
Last month there was an interesting essay in the journal PLoS Medicine, about how most brand new research findings will turn out to be false (www.tinyurl.com/ceq33). It predictably generated a small flurry of ecstatic pieces from humanities graduates in the media, along the lines of science is made-up, self-aggrandising, hegemony-maintaining, transient fad nonsense; and this is the perfect example of the parody hypothesis....

Statistics are what causes the most fear for reporters, and so they are usually just edited out, with interesting consequences. Because science isn't about something being true or not true: that's a humanities graduate parody. It's about the error bar, statistical significance, it's about how reliable and valid the experiment was, it's about coming to a verdict, about a hypothesis, on the back of lots of bits of evidence.

But science journalists somehow don't understand the difference between the evidence and the hypothesis.

...

So how do the media work around their inability to deliver scientific evidence? They use authority figures, the very antithesis of what science is about, as if they were priests, or politicians, or parent figures.

...

The danger of authority figure coverage, in the absence of real evidence, is that it leaves the field wide open for questionable authority figures to waltz in.

...

But it also reinforces the humanities graduate journalists' parody of science, for which we now have all the ingredients: science is about groundless, incomprehensible, didactic truth statements from scientists, who themselves are socially powerful, arbitrary, unelected authority figures. They are detached from reality: they do work that is either wacky, or dangerous, but either way, everything in science is tenuous, contradictory and, most ridiculously, "hard to understand".

This misrepresentation of science is a direct descendant of the reaction, in the Romantic movement, against the birth of science and empiricism more than 200 years ago; it's exactly the same paranoid fantasy as Mary Shelley's Frankenstein, only not as well written. We say descendant, but of course, the humanities haven't really moved forward at all, except to invent cultural relativism, which exists largely as a pooh-pooh reaction against science. And humanities graduates in the media, who suspect themselves to be intellectuals, desperately need to reinforce the idea that science is nonsense: because they've denied themselves access to the most significant developments in the history of western thought for 200 years, and secretly, deep down, they're angry with themselves over that.
Glenn Reynolds quotes from the penultimate paragraph:
Science is done by scientists, who write it up. Then a press release is written by a non-scientist, who runs it by their non-scientist boss, who then sends it to journalists without a science education who try to convey difficult new ideas to an audience of either lay people, or more likely - since they'll be the ones interested in reading the stuff - people who know their way around a t-test a lot better than any of these intermediaries. Finally, it's edited by a whole team of people who don't understand it.
Reynolds adds,
In other words, it's like the rest of the news . . . .
