[_delirium]

I don't think the kids are doing too badly on that one, though, because you'd get results not entirely dissimilar if you polled working biologists. CCD is a particularly tricky example because everyone agrees that something is happening, but no causes have proven links. Yet there presumably is some cause or set of causes, so scientists differ in their hypotheses as to what those causes might be. I suspect if you were to poll, you'd find that very few think a link to cell-phone towers is probable, but quite a few think a link to pesticides is probable.
