PalMD has writ­ten a great piece over at Deni­al­ism, which echoes a lot of the sen­ti­ments I’ve pos­ted about here over the years.

It’s well writ­ten, true, and I liked it, so I’m link­ing to it.

There’s a great art­icle over at the BBC, about what hap­pens when you give the cli­mate change deni­al­ists a chance to present their side of the argu­ment. You get

The sum total of evid­ence obtained through this open invit­a­tion, then, is one first-​​hand claim of bias in sci­entific journ­als, not backed up by doc­u­ment­ary evid­ence; and three second-​​hand claims, two well-​​known and one that the sci­ent­ist in ques­tion does not con­sider evid­ence of anti-​​skeptic feeling.

While I’m not sur­prised that these people com­plete failed to back up their claims of sys­temic bias in the sci­entific com­munity, I don’t share Mark’s view that the whole exer­cise was a waste of time. Sure, we knew they wouldn’t come up with the goods, but it’s worth doing the leg­work to prove that to the pub­lic at large, espe­cially if you can get that res­ult pub­lished on a hugely pop­u­lar site like the BBC.

Also, if someone goes through these motions every once in a while, then it gives the deni­al­ists less scope to claim they’re being oppressed. Of course they won’t stop; they’ll just claim that this a piece of estab­lish­ment pro­pa­ganda, but for every art­icle like this that is pub­lished, the pub­lic at large will be less inclined to give those claims credence.

A little while ago, I indul­gently fisked an idiot com­menter at the Guard­ian, and in doing so out­lined my reluct­ance to resort to such tactics:

I try to avoid fisk­ing because it makes me feel nit-​​picky; I’d rather address the sub­stance of someone’s argu­ment or pos­i­tion, than hope that knock­ing enough little holes in it will have the same effect.

The other thing I should have said, of course, is that it’s basic­ally an argu­ment of the gaps. That is, shred­ding someone else’s pos­i­tion doesn’t neces­sar­ily make me right; why waste time show­ing the flaws in someone else’s argu­ment, when I could be explain­ing and pro­mot­ing my own position?

Aside from the obvi­ous reas­ons above, Deni­al­ism has repor­ted on some new research that intro­duces an inter­est­ing angle. The research isn’t dir­ectly about the prac­tice of fisk­ing, but it applies, I think:

When Uni­ver­sity of Michigan social psy­cho­lo­gist Norbert Schwarz had volun­teers read the CDC flier, how­ever, he found that within 30 minutes, older people mis­re­membered 28 per­cent of the false state­ments as true. Three days later, they remembered 40 per­cent of the myths as factual.

Younger people did bet­ter at first, but three days later they made as many errors as older people did after 30 minutes. Most troub­ling was that people of all ages now felt that the source of their false beliefs was the respec­ted CDC.

So, all those rational blogs out there, whenever they quote old crank canards, in order to shred them in the next para­graph, might actu­ally be re-​​enforcing belief in those lies in their tar­get audi­ence? That’s a pretty big deal if it’s true, and it might force a lot of blog­gers to change the whole way they present their arguments.

Of course, the research is not widely applic­able; it deals spe­cific­ally with widely held, and often repeated myths, rather than the sort of totally out-​​there crankery that occa­sion­ally sur­faces on the inter­net. So, I’d guess we’re still fine to quote some crank claim­ing that we all go through a bal­loon animal phase dur­ing early devel­op­ment, but we might want to think twice when we’re oppos­ing some other crank arguing that Dar­win­ism leads to Nazism, or that the Amer­ican found­ing fath­ers were all prac­tising, main­stream Christians.

It’s worth bear­ing in mind, at any rate.

I want to link to this art­icle on the eth­ics of stem cell research from the excel­lent Deni­al­ism blog for a few reas­ons; it’s well writ­ten, it’s top­ical, I agree with it entirely, but most import­antly it’s rel­ev­ant to an argu­ment I had a with a good friend on the train a couple of weeks ago, and I and only wish I’d got my point across nearly so effectively.
