The paragraph immediately below in the paper states: > At the 14-week interim evaluation, there were increased incidences of right ventricular cardiomyopathy in the heart of male rats following exposure to GSM- and CDMA-modulated cell phone RFR compared to sham controls. And a little further down: > Following exposure to GSM- or CDMA-modulated cell phone RFR, there were increases in the incidences of malignant schwannoma in the heart of male rats

Right, that's the p-hacking section. If the death rate goes down and also the causes of death shift around, it's dishonest to focus narrowly on the subset of causes of death that went up. And if you look at so many different things that something as obscure and specific as "malignant schwannoma in the heart" is, then your paper better mention multiple-hypothesis correction, which this one doesn't. (I predict that this paper, which went to the press before peer review, will not pass peer review, for this reason.)

  As a person who reads papers and is (seemingly) confident in their ability to debunk claims that manipulate data, could I ask your advice? How do you approach hot-button questions in health-related fields? I find it hard to navigate the deluge of information out there related to keeping in good health re: diet, exercise, personal routines and habits, etc. It feels like there are so many conflicting opinions, all with people trying to influence your behavior and nudge you towards living one way or another. Weasel words, twisted data, fake news, or whatever you want to call it seem to be a big part of this, too. To relate to this specific post, I'm taking a course as part of my EE degree right now on EM Wave Propagation and even that prof gave a little talk about the negative health risks of cell phones, which I found... odd, to say the least. I still don't know what to make of his cautionary words, or whether I should take them to heart. I feel ignorant and naive, and am unsure of how to live my life at times. What do you do to navigate all of this?

    Never start from a news article, unless your goal is to help others by debunking it. News articles rarely reflect the research they claim to report on, and even if they did, they'd be reporting on a highly skewed subset of the research. Read sources that are intended for people who genuinely care about getting the right answer. For exercise, that means writing where the target audience is professional athletes and their coaches. For nutrition, try to start from Wikipedia (if you don't have a specific question) or PubMed (if you do). Carefully avoid anything that's focused on weight loss, because that's where the crackpots, laymen and officially-respectable conmen are. Japan has the longest life expectancy and the lowest obesity rate. Every time you see a claim about what a good diet is, check it against the Japanese diet; if the Japanese are doing the supposedly-bad thing, reject both the advice and its source.

      I'm not sure whether your reasoning about Japan is a good way to evaluate things. That's because Japan could be different because of a particular thing out of all the possible factors. The reason I say that is because I am thinking of the effect of lead exposure on crime rates as an analogy. There are a million things that could and probably do affect crime, but lead in the environment seems to dominate. If the Japanese are particularly healthy, it could be to one particular factor, say fish oil consumption (just to be arbitrary) and everything else might conceivably be irrelevant or harmful. Assuming the "goodness" is distributed equally among the various characteristics of the typical diet could lead you astray when you focus on something that doesn't matter or is harmful. It's the same issue as if you observe some people living a very long time while smoking - is smoking contributing to their lifespan or working against it?

        It's not a completely reliable heuristic, but it's easy to check, and the things it's flagged that I've checked have turned out to be bullshit. (Sometimes highly respectable, promoted-by-mainstream-institutions bullshit, but not supported by quality studies if you read carefully.)

  Those quotes were to show that the article didn't take findings out of context - it was a restatement of things in the paper. According to the article it's already passed peer review, where reviewers upgraded the findings from 'equivocal' to 'clear' evidence. Both the article and paper seem to focus on cancers - not death. Side observation -- does this mean cell phone radiation actually reduces kidney failure rates?
