    I sympathize. I, too, have trouble keeping in touch and submitting things on time.

    Some lady on FB threatened to report me to the police--for saying cops in sthlm are jerks for harassing beggars w/out solid legal basis and compiling illegal databases of Roma and women who're victims of abuse--because my name doesn't sound Swedish it is one of the weirdest expressions of xenophobia I've seen so far in this country.

    I must say, that seems a bit much. On the other hand, you are living in Sweden.
    Greece shows us that there is a kind of politician worse than the ones that break their election promises; the ones that keep their election promises.

    Just another day where Trump really IS president; congress isn't fulfilling their constitutional mandate of oversight; and the "balance" between co-equal branches of government is more like a reality TV drama series or beauty pageant. Return to Trump, negative feedback loop, recurring nightmare, WTF

    You are though. It's just a matter of perspective innit.

    Well indeed, and I'm quite happy to be called far left compared to that nasty piece of work.

    Spoiler:
    New recruit that we'd just started. Added everyone on Facebook and while a few of us were drinking in the bar and my wife found a bunch of anti-Islam cartoons he'd shared including one where a pig was shagging a Muslim woman captioned "you'll learn to love pork." Disgusting. He said "I'm not racist, its just Muslims are terrorists". That's pretty much the definition of racist you moron. It's illegal to sack someone because of their politics but the next day he said he had to go home early for the third time in the two weeks since he'd started which is far too unreliable so we decided not to give him any more shifts on that basis then a week later he comes in screaming that we sacked him because he votes UKIP.

    Water is falling from the sky.
    It's getting closer now, the fear that we have held off for so long
    It's getting closer now to where we know there can be no return
    It's makes no sense to me, what has been set in motion here today
    It makes no sense anymore, was it too little, too late? Or too much too fast?

    "we continuously increased the number of animals until statistical significance was reached to support our conclusions."

    Exact quote from an article published in Nature, arguably the top journal in the natural sciences. WTF?

    First off, it's from Nature Communications, a much lower tier part of the NPG family (impact factor 12.4 vs. 40+ for the real deal). Secondly, it really depends what you're trying to show to determine whether this is problematic. Generally for animal studies you do a pre hoc analysis to determine sample size. But the dirty secret is that everyone's power analysis is garbage - you generally don't know the expected variability in your data, you almost certainly don't know the expected differences you'll be observing, and choosing a power of 0.8 and alpha of 0.05 is more or less arbitrary (albeit standard).

    Doing the kind of study reported here is valuable if you're really just trying to get information about the population(s) you're studying - essentially, the size of an effect and the variability in your data. Studies published in the likes of Nature Communications often provide this level of evidence. It's not great for hypothesis testing, but that doesn't mean it isn't okay science. Hell, pretty much all of particle physics is just smashing stuff together enough times that you get a signal that meets a given set of criteria.

    The big issue here was whether they were running multiple statistical tests on the data without providing adjustments for p-values afterwards. This is a very common sin, and accounting for it is crucial to make sure you're not just reporting noise instead of real data. It might indeed be a big problem but without a clearer understanding of what they did it's hard to know.

    Good catch on the journal name.

    If the purpose of the study is to see whether X has a statistically significant effect on Y, you can't just up the sample until your p-value reaches an acceptable level. This is p-hacking taken to the extreme, and the authors nonchalantly admit to it.

    If your data has substantial variability, then it should be hard to obtain statistical significance. That's the whole point. If you want to claim there's a large effect size, that's fine. If you want to claim hypothesis testing is unnecessary and that you're just providing summary statistics, that's more or less fine. But you can't have your cake and eat it too by doing hypothesis testing and then explicitly changing the parameters of the study until you get the desired result. Or at least you shouldn't admit to doing it.

    I suspect that your critique is fair but I think it's important to distinguish this from p-hacking. P-hacking is essentially going in with no hypothesis, getting a shitload of data, and then running every test you can imagine until something 'significant' appears. This is distinct; they had a hypothesis but didn't know either the effect size or the population variance, so they scaled sample size to find the effect. It's potentially got some of the same problems with p-hacking if they didn't account for multiple post-hoc tests when reporting p-values (I suspect this is the case) - but it's not as dishonest as p-hacking. They're essentially saying 'we're pretty sure there's a signal here, the size of the effect we saw was X' rather than 'we had a hypothesis that Y effect exists and is this size, and sure enough we were right'. It's a bit sloppy science, since ideally they would have run a pilot study to inform their power analysis, but the fact of the matter is that no one does that.

    For subtle signals in in vivo data, I would indeed prefer to see at least one replication (or partial replication) before I'd submit this kind of data. And that would obviate the need to justify their sample size in this manner. But it's still informative IMO, even if it means your conclusions are far weaker than they might be otherwise.
