I'm a physicist who has done work on data analysis in cancer genomics. The depth and complexity of cancer biology is enormous, and "following the evidence" is the work of years.

It's easy to follow superficial arguments about specific experiments. It is very, very difficult to get hold of the ambiguous morass that is the true leading edge, which is so far away from the layperson's event horizon they aren't even aware it exists, and so end up believing that it's not that hard to follow the evidence in most situations.
