According to James D. Williams, here is the brainwashing plan that gets it done:
With creationists targeting young children with books, .e.g., “Dinosaurs by Design” or “Dinosaurs of Eden,” or comics and posters that refute science and replace accepted geology with tales of a global flood, misconceptions can be implanted very early on. This tactic was reported by the author at the 2009 British Humanist Association International conference in London. Creationists appeal to the interest that children naturally have in dinosaurs and fossils. Using this appeal to reinforce a misconception is nothing short of an intellectual abuse of children through what I call “insidious creationism,” the deliberate, slow, subtly harmful implanting of a scientific untruth. This is not done by the creationist community through ignorance, as those responsible are fully cognisant of the actual scientific standpoint on evolution and its acceptance by the overwhelming majority of scientists. Since evolution as a concept is not formally taught in primary schools in the UK, it makes such challenges to creationist misconceptions harder to mount.
