So who's to blame for all these bad stories and the sorry state of health journalism? One new study, published in the British Medical Journal, assigns a large fraction of blame to the press shops at various research universities. The study found that releases from these offices often overhype the findings of their scientists — while journalists play along uncritically, parroting whatever showed up in their inbox that day. Hype, they suggest, was manufactured in the ivory tower, not the newsroom.
