A longstanding problem is that science writers tend to act as cheerleaders instead of constructive critics. Most of the probing questions that could have been asked about many hyped claims do not require advanced degrees, just a tendency to compare different teams’ findings and ask the tough questions.
Because science boffins often want it that way. The biggest temptation for science journalists is to be cheerleaders instead of thoughtful and constructive critics. Everybody loves the cheerleader; the critic, however kindly and well-meaning, well — is just not loved so much. So one must be willing to be unpopular at times.
