I hoped that it wasn't as bad in computational biology, or ecology, or any other biology field where systems and models are actually defined. It saddens me to read that your experience was as bad as mine...
I also agree on the innocent until proven guilty part, but by now I've seen and talked to hundreds of people with the best intentions, who do not realise how important careful examination of the data is, so I'm growing a bit disillusioned.
(My impression from admittedly limited contact with biology students and from browsing through the occasional paper is that most of them barely approach mediocrity from below.)
