There are many problems with science journalism these days. One of the most important problems is that their sources (scientists) are highly unreliable as we witnessed in the recent Darwinius Affair.
One of the other problems is that science journalists have been very reluctant to criticize each other and maintain certain minimal standards of reporting. They are much more interested in giving each other awards for good writing than they are in evaluating good science.
Carl Zimmer has become an exception to the rule.1 He has taken on the role of defending his profession against those science journalists who would abuse science for the sake of a high profile publication [George Will’s Crack Fact-Checkers Continue Their Nap]. We need more journalists like Carl Zimmer and we need more scientists who will chastise their less-than-scientific colleagues when they step out of line.
