As Andrew Brown of the Guardian sees it:

Someone for whom all numbers above about a thousand are [an] indistinguishable blur may very well think that the earth is 10,000 years old and mean by this that it is really really seriously, like, old.
Such people don’t pose any threat to the teaching of science in schools. They just make it look entirely pointless, since they have themselves been “educated.” But that is a different and more serious problem than religious creationism. The anti-Darwinians interviewed in the most recent survey are a tiny, articulate, and self-conscious minority. The real problem for public understanding, as anyone knows who has done any science writing, are the millions of people whose position is that they don’t know, don’t care, and don’t want to do either.
