Quote of the Week

All things must be examined, debated, investigated without exception and without regard for anyone's feelings... We must run roughshod over all these ancient puerilities, overturn the barriers that reason never erected, give back to the arts and sciences the liberty that is so precious to them.

Denis Diderot

News Items

Bright Spots on Ceres (9:37)

Clinical Science (14:25)

S: Alright, let's move on, the next item I want to talk about, this is an interesting one, this is about the essence of the disagreement about the nature of medical research between science based medicine and alternative medicine proponents. If you recall, about six months or so, David Gorski and I had an article published where we essentially argued that doing clinical research on therapies that are essentially magic, they're so impossible that you might as well think of them as magic, is a waste of resources.

E: How controversial.

S: Yeah, right, exactly. But obviously the alternative medicine proponents were not happy with our opinion because everything they do is essentially magic. If you accept the fact that you shouldn't research things like homoeopathy, the homoeopaths aren't going to like that. So there was a lot of push-back, a lot of criticism of our article, all nonsense, nothing that we hadn't heard before. Again, in my opinion, the alternative medicine community is intellectually bankrupt, they have nothing new or interesting to say, their ideas have been completely demolished long ago, they're on a par with the creationists, really. They're just recycling the same logical fallacies over and over again. As evidence for that, a recent article was published by Sunita Vohra and Heather Boon in an alternative medicine journal, once again criticising David Gorski's article, David Gorski's and my article, although they misspelled his name Gorki. Gorki and Novella. (laughs) David hates that.

E: Nice (laughs).

J: It's awesome, right?

S: In which they recycle the same tired, old arguments. But here it is. I just wanted to summarise, to use this as an opportunity to summaries the Science Based Medicine opinion and what they're saying. So fist they say that essentially you shouldn't use prior plausibility to determine what ideas in science should be researched.

B: Oh god.

E: How convenient.

B: Seriously?

J: What?

S: Essentially, their agument, this is their argument, this is their actual logical argument, although they're not as pithy as this, but it boils down to: we don't know everything, therefore we should behave as if we know nothing. That's their argument. Their argument is: we don't know everything. And then they erect a bunch of straw men about what our position is.

B: Logical fallacy.

S: Yeah, our position is not that we know everything. And they also, interestingly, flip one of our arguemnts, which again, they're not even following the basic logic of our argument. We would say that basic science, if a treatment looks promising from a basic science point of view, you still need to do high quality clinical studies because just looking promising in the test tube isn't enough and doesn't really predict what's going to work clinically, you still have to do the clinical research. They take from that the reverse argument that things which look impossible at the basic science level still may work.

E: Oh my gosh.

S: But you can't do that, I mean that doesn't make any sense.

E: So kabooki dances and voodoo are just as plausible as anything else out there.

S: Yeah, exactly. Yeah, why not spend money studying voodoo. Yeah, exactly. Which, homoeopathy is on that level, it's magic, it's complete magic. They actually pull the Galileo gambit, they mention Galileo by name.

E: Of course.

J: Oh, not again.

E: That old chestnut.

S: Yeah. So, that's number one, prior plausibility, scientific plausibility is right out, that's just bias and so we should act as if we know nothing, as if everything is a brand new question, it's a new day. Number two, and this is really, think about the combination of these two things. Their second big point is, it's like yeah, but we get, because our argument is, it's a waste of resources, we have limited research resources, we can't do definitive efficacy trials of every crank idea, we have to pick and choose which ones are likely to work out, you know?

E: Right, limited resources, hello?

S: So here's their solution.

J: Uh, oh.

S: You don't waste resources doing large, definitive efficacy trials, you could do smaller trials like n of 1 trials. N of 1. That's one person. Or you could do pragmatic studies. Pragmatic studies are designed for comparing the real world application of proven therapies, they're not placebo controlled, they're not efficacy trials. So get this: they want to simultaneously throw out prior plausibility and appeal to the weakest form of clinical evidence. So they want to support their treatments with low-grade clinical evidence without any appeal to scientific plausibility. That's their solution.

B: Well that's the only chance they have.

S: Of course.

B: Right?

J: Well they could change their freaking minds.

S: Yeah, or they could respond to the actual evidence. What we're saying is, you know. The other thing is, it's not as if these things haven't been studied, like for example, there was just yet another review of homoeopathy which I wrote about on science based medicine today.
