One of the letters in this weeks New Scientist reports the reassuring facts that, despite the antics of various school boards and the attempts of numerous kook religion sites, Creationism is in decline. This is good news, and personally I would like nothing more than to think it was true – in fact if you base your analysis on my personal experience, then hardly anyone believes the creationist nonsense.

Sadly, I am not (yet) fully convinced that this is the true description of the world.

Now, the letter in NS helpfully produces some figures to support its claim. This is nearly always a good thing but this time it seems to be a touch confusing. Look at this:

Since the 1980s in the US the fundamentalist opinion that Adam and Eve were created a few thousand years before the pyramids has held fairly steady at between 43 and 47 per cent, with the lowest value occurring in 2007.

OK, it seems reasonable to take from that sentence the idea that creationism fluctuates around 45%, give or take 2%. While it is reassuring to see creationism is at its lowest last year, that is not really a decline.

Interestingly the numbers are compared with:

The number believing in human evolution under the guidance of God has stayed between 35 and 40 per cent.

The number agreeing with the scientific consensus that evolution occurred without a god has risen from 9 or 11 per cent at the end of the 20th century to a high of 14 per cent in 2007.

Sadly, this is less reassuring. I am not sure how three effectively stable sets of numbers can be used to show creationism is in decline. Equally, (admittedly ignoring the variation with the start figure of proper evolution) the numbers all show basically the same variation. Going from 11% to 14% is not a significant change when 47% – 43% is described as “fairly steady.”

As far as I can see, from the three sets of figures here, the numbers are all basically “steady.” All have about a 5% spread which seems to fluctuate. This is, in itself, not a downward trend for creationism.

Can anyone else show more positive figures?

Equally lacking in comfort to the rational is the information that, in the worlds only superpower, a nation with the ability to destroy every living person:

Remarkably, the number taking the Bible literally has steadily sunk from about 40 per cent in the 1970s – nearly matching those who then favoured the Genesis story – to between a third and a quarter.

So, at best, 25% of people still take the Bible literally. Wow. Scary wow.
