Striking a blow against false balance

Referencing the Flint water crisis, Tara Haelle explains why reporters are justified in ignoring or discrediting fringe commentators who suggest that news about lead in drinking water is overblown: "They’re even entitled to say it, just as anyone can claim the Earth is flat, the moon landing didn’t happen, the sun circles the Earth and cavemen rode dinosaurs. But the facts reveal a real crisis that every other politician inside and outside Michigan is taking seriously."

In defense of journalistic independence

Two months after raising questions about plant scientist Kevin Folta and his ties to Monsanto, Brooke Borel posts on the differences between science communication and science journalism](http://bit.ly/1NSB4D3): "Should political journalists stick to positive profiles of politicians? Should business writers only consider the positives from a company’s actions? Should those who write about literature ignore the intent of the pieces they cover? Of course not. And the same goes for science."

Obama's obstruction of climate coverage

The president's climate rhetoric is offset by a lack of transparency, Dawn Stover writes, citing stories on a Keystone pipeline briefing that "quoted a 'senior State Department official.' Perhaps a more accurate description would have been 'Senior State Department Official Number One, who spoke at a press conference but declined to be identified by name or to give a reason for requesting anonymity.'" More on Paris coverage from Cristine Russell.

Why p-values are so hard to explain

Even scientists have trouble explaining, in plain English, what a p-value is, Christie Aschwanden writes after posing that challenge at a recent statistics conference: "To be clear, everyone I spoke with at METRICS could tell me the technical definition of a p-value — the probability of getting results at least as extreme as the ones you observed, given that the null hypothesis is correct — but almost no one could translate that into something easy to understand."

The state of health press release reviews

More than six months after Health News Review began reviewing press releases, managing editor Kevin Lomangino writes about what it's finding and how PR people are reacting: "In several cases, public relations officials have written to us privately to say, 'But the researchers signed off on what we wrote!' To which we reply: 'That’s not good enough.' … But we’ve also had many terrific interactions with press officers who’ve been open to our constructive criticism."

The latest resurrection of Jonah Lehrer

Jonah Lehrer in 2009

Carlos Lozada writes about the fabulist's latest credit, ghostwriter on a new book by UCLA behavioral economist Shlomo Benartzi, The Smarter Screen: Surprising Ways to Influence and Improve Online Behavior: "Of course, Lehrer is far better known than Benartzi, but when fame turns to infamy, this is what you get. Jonah Lehrer has been reduced to a 'with' — a prepositional demotion." Also, Stephen Glass repays Harper’s for one of his articles.

Why science literacy is hard to change

With even presidential candidates spouting anti-vaccine views, one might think that science communicators are to blame for the public's poor science literacy. Rick Borchelt disagrees: "What little evidence we do have is that science communication and other informal science learning are at best of marginal value to boosting adult scientific literacy — way, way, way behind such factors as years of total educational attainment and number of college science classes taken."

Why cost is part of the cancer drug story

Harold DeMonaco reviews a recent commentary on cancer drug costs and concludes that journalists should do better: "The good news is that newer drugs can prolong lifespan and improve the quality of life of cancer patients. The bad news is that these drugs are rapidly becoming unaffordable to the average American. In many instances, health care journalists don’t seem to be telling their readers about the rising cost of these drugs and what that trend means for patients."

Why it's so hard to get science right

Christie Aschwanden uses a clever interactive graphic to explain why so many scientific studies don't hold up under further scrutiny: "I could pontificate about all the reasons why science is arduous, but instead I’m going to let you experience one of them for yourself. Welcome to the wild world of p-hacking." Aschwanden's graphic shows how an insignificant result can be turned into a significant one by manipulating a few of the handful of variables in the analysis.

The Hippocratic Oath and journalism

From Dr. Oz to Sanjay Gupta, Rita Rubin discusses physicians who practice journalism and the hazards they face, from NBC's Nancy Snyderman being criticized for violating her self-imposed Ebola quarantine to CBS's Jennifer Ashton wearing a pink ribbon while reporting on breast cancer: "These situations highlight what one journalist, who also is a physician, calls the potential 'minefield' of navigating two professions that have different ethical standards and goals."
