Although true this isn't quite the whole story. The seven percent is from a group of "elite" scientists - the same survey carried out on a more general group of scientists gave a figure of forty percent who believed in God. This is the same result (give or take) that a survey carried out in 1916 came up with.
Details are in the
University Of Georgia Research Magazine. Larson discusses why the poll of the NAS members gave a much lower value than the one of general scientists. In a
linked article he talks about the difference in results between different branches of science as well. Apparently physicists are less likely to believe, mathamagicians more likely.
BTW creationistal, as you (like me) are fairly new here, I'll pass on a tip I realised while lurking here originally. If you post a reference to something it's always a good idea to have done some checking for related/conflicting information first. Often just a quick Google search is enough - I'd never heard of this before but I got my info just by putting "Edward Larson" into Google. Not doing this is a sure way to get jumped on by somebody here !
Second free tip - it's always better to try and get to the original source rather than a referencing one (and I know the Research Magazine isn't actually the primary source but it's close enough for me
).
