Funding bias affects all fields

We've known for a while that the results of pharmaceutical trials are influenced by the source of funding. Now two separate studies have been published showing that the same is true in the fields of nutrition and technology. I suppose it's unsurprising. The results you get out of research depend on the questions you ask. And the questions you ask depend on why you're asking them. I think all we can do is make the sources of funding as explicit as possible, and do regular comparisons along the lines of the studies linked to here in order to be able to correct for any bias that results.

This is just plain scary

I don't think I'll trust the Times again.
As the author points out, it's impossible that the authors of the article in the Times couldn't have known that they were writing falsehoods; that is, if they were doing any research into the subject at all.

How many more such articles are there out there? Mark Liberman at the Language Log points out that calling foul on news articles in the mainstream media is becoming more possible with the possibility for everyone to publish through blogs. And this is a good thing.

We've seen this before, of course. It's called peer review'. Philica even offers a very similar system of review to that of the blogosphere, with articles being published first and then reviewed. But there's a lot of drivel there, and who is going to have time to look through it all? Nature has recently given up on a test of open peer review for lack of uptake. I don't see academia moving over to this system any time soon. But as for popular reports, take everything you read with a pinch of salt. Or, in the case of the Times, empty the whole bag in.

DaimlerChrysler climbdown

I see that DaimlerChrysler has issued a statement, in response to the BBC news article claiming that their chief economist dismissed the notion of climate change as 'Chicken Little' behaviour. Apparently he just said that other people said that, not that he agreed with it.

I would tend to wonder why, if he didn't agree with what he was saying, he said so much of it (the BBC article quotes quite extensively). But it is in car and oil companies' interests to at least appear in public to be green. The New Scientist points out that companies like BP, who market themselves strenuously on their green credentials, are doing much better than ExxonMobil. And this is especially important when, as the BBC article points out, the US economy is struggling. So the damage limitation people are out in force.

At the same time, there is a petition against the proposal to introduce mileage charges instead of the current flat-rate road tax. This follows the fuel tax protests in 2005. Personally, I would prefer fuel tax to a GPS-based system, simply because the former is so much easier to administer. But either way, the protests are about the increased cost of driving around per se.

I would love the facts about pollution to turn out to be wrong. I would be very happy to continue my current profligate Western lifestyle. But I think that it would be fooling myself to ignore the warnings. It's not a matter of Chicken Little yelling that the sky is falling because an acorn fell on his head. Chicken Little has been pointing out, at length, for several years that the sky is now measurably lower than it was in the past, and although estimates disagree on the rate of descent, they all agree that it will fall further, that we know what is causing the sky to fall, and that the consequences of falling sky are already visible. Since people aren't going to change by themselves, we need legislation, such as higher taxes on fuel. So it's time to go and see the King.

I can't imagine why

I really cannot fathom why any doctor would refuse to inform a patient of their diagnosis. For years. Of a serious illness for which such treatment as there is needs to be started as early as possible.

Medical journalism corruption still rife

This week's New Scientist has an article showing that drug companies have not stopped their attempts to influence the media in favour of their products, attempting to cover over controversies and suppress reporting of inconvenient results.

Nine years old forever

I was surprised, though pleased, to see the general response to the Ashley treatment. I was expecting much more of a knee-jerk reaction, but people have for the most part been very understanding in their comments. Maybe this is a UK/US thing, since US boards seem to have a much harsher take on it. Or maybe this is because the story broke in the US first, and so the UK people, posting later, have a fuller view of the case?

In case it's not clear, my sympathies, too, are with the parents. It would be nice if such decisions didn't have to be made, but the world isn't like that.

Thanks, but no thanks

The charity Sense About Science is asking celebrities and journalists to check the facts before supporting any campaigns. I think this is a great idea, and a good response to Lord Rees' comments a while back. It might even make a difference to some of the more barmy campaigns out there.
