Comment Re:A bit sad but no great surprise (Score 1) 110

But sometimes a catchy tune is good and you're not somehow less good because lots of other people like it too.

This is definitely true and I also agree that one shouldn't be snobbish about popular culture. That said, it's also true that you can have your cake and eat it: there's plenty of good music that also has good tunes.

Comment Re:Short term gains, long term losses (Score 1) 110

Heh. Pop music is by the most varried of ALL genres. Other genres limit themselves to certain structures, where pop music just needs to be popular, and can take crossovers from any other genre if it is widely accessible enough.

I don't think "pop music" is a genre, I think it encompasses multiple genres. So on the one hand, by virtue of being a catch-all term, pop is varied. On the other hand, mainstream popular music must now grab the listener as quickly as possible on the first listen. To achieve this new songs must have a lot of familiar content and they must be simple. This pushes mainstream popular music towards less variety and less depth. Thus I don't think pop music is the most varied of all genres: it's mostly recycled candy. If you want the three course meal you need to look elsewhere.

Comment It's not even clear what "psychological" means (Score 1) 273

Central to this is the assumption that "psychological" means "made up". It doesn't have to the be that way. Consider classical conditioning of Pavlov's dogs: bell ringing predicts food and eventually bell ringing on its own causes salivation of dog. Is that psychological or physical? Is this just a semantic difference? The conditioning is underpinned by a real pathway in the brain that's been created and/or strengthened: so that's a physical thing. But ultimately you only know this has happened by watching the behavior of the animal: which is closer to "psychological". They're both two sides of the same coin.

What if chronic fatigue syndrome is somehow like that? What if somehow these patients have a condition where any exertion triggers a strong and abnormal fatigue response and this leads to a vicious circle wherein they get more tired with progressively less activity. That would explain why the condition is so resistant to treatment and why it has no obvious measurable hallmarks other than fatigue.

Comment Re:Fortune favors the well prepared (Score 1) 480

It's a really really old saying. So yes luck bestows merit but the important part isn't that. True Merit is needed to take advantage of Luck. Nearly every experimental graduate student will tell you it takes 2 weeks of work to get a PhD but it takes 5 years to find be prepared to recognize the 2 weeks.

Working in a research lab, I feel that ratio is pretty far off. It's a lot more than 2 weeks. If stuff goes badly, maybe you have to chuck out 3/4 of your experimental work. If stuff goes well, all your experimental work goes into your thesis.

This type of thing never works, it just makes the people who already believe in this hunker down because now they believe it's an even bigger conspiracy. If you want to get people to stop believing in this, just make a pro-vaccine movie. Only you don't fill in full of scientists, reason and logic. Go film some of the anti-vaxxers whose children got sick with perfectly preventable diseases. Make sure to really capture the suffering of those poor children and the misery of the dumb-fuck parents. Go to the corners of the earth where polio still exists to show them the horrors of that. I think that will get their attention.

It probably won't get their attention: they are blind to reason. They will just think the film is propaganda and either not watch it or do so but use twisted logic to disregard it. People believe the Earth is flat, so believing vaccines are bad for you is a far easier delusion to maintain. The only thing that might change their minds is if their kids die or are debilitated by the diseases they are failing to vaccinate them against. Their current belief system has little of any obvious repercussions on themselves, so it's easy to continue the self deception.

We should replicate studies and confirm analysis independently before we get too excited about any results..

That's true, but the hitch is there will be financial interests working and braying about whatever study gives them better profit opportunities.

That doesn't stop the individual from looking at Cochran reviews and so forth to get a more balanced picture and making up their own minds. I do this whenever the media bring up a new study making some claim or other.

Submission + - New AI text generator may be too dangerous to release

umafuckit writes: The Guardian reports that GPT-2, the new text generator from OpenAI, is so good that it risks being used to malicious ends. As a result, OpenAI are delaying release. The model underlying GPT2 has been trained on 40 GB of text data and is able to write highly realistic prose. For example, after being fed the first few paragraphs of a news story, the AI continues with the paragraph: "Asked to clarify the reports, a spokesman for May said: ‘The PM has made it absolutely clear her intention is to leave the EU as quickly as is possible and that will be under her negotiating mandate as confirmed in the Queen’s speech last week.’”

Is this text generator truly groundbreaking or is the delay in release just a tactic to attract attention to it?

Comment Re:Better but still glitchy (Score 0) 44

Despite giving it a few weeks however, I just couldn't warm up to it. No one big thing, just a lot of little things that made the experience feel like it was still an unpolished pre-release.

So it's still not quite as good as KDE 3, then? The good news is that it seems to be getting there. Probably around 3 or 4 years to go at this rate of progress.

That the greens have predicted. I never thought you could do worse than economists and still be called a science. Maybe they should change their name to climate studies and be moved in with the gender studies people.

This is a dangerous and foolish attitude to take. The threats facing humanity raised by the "greens" -- your chosen term not mine -- are real, quantifiable, and ongoing and will not go away because a particular milestone has not been reached when predicted. There are crystal clear and very worrying trends across a range of domains such as climate, deforestation, availability of fresh water, insect populations, desertification, and pollution. Brushing them aside because the "apocalypse" hasn't happened yet is beyond silly.

I agree that the small sample size is no proof of any malign intent, however, the tiny sample size with no explanation of why the sample size is so small, the use of graphics instead of presenting the raw data

On reflection, I take back the raw data statement (which was made WRT to lack of data points overlaid onto error bars -- a common thing in the field). There ought to be more detailed analyses of what individual bees do.

I agree that the small sample size is no proof of any malign intent, however, the tiny sample size with no explanation of why the sample size is so small, the use of graphics instead of presenting the raw data and the fact that they never appear to have considered memory being sufficient to explain the results without any claims that "bees can add/subtract" are all worrying signs that the study is worthless.

Based on what I see in the field in general, I wouldn't say n=14 is "tiny". I would say it's "OK could be better" but of course that depends on SD and effect size too. As for the lack of raw data points, that's inexcusable (i.e. there is no reason not to do it) but unfortunately very common indeed in this field. I've found from experience that you can't write off a paper just because they miss out the raw data points: you'd throw out 90% of the field and it wouldn't make sense. FWIW, authors are obliged to send a reader raw data upon request. I've not really read the paper, but based on the figures it seems they lack controls of the sort you mention. That's the problem. The rest I can live with.

You may get drift in behavioral scores over time, batches of insects that produce suspect results, etc.

Yes, that's exactly the problem here. These guys got a batch of bees that happened to score 65% and cherry picked that as proof that the bees can do arithmetic.

If they did that, it's gross data manipulation. You don't know that they did that and there is no evidence that they did.

This isn't like they are studying the remaining living WWII veterans or Japanese anorexics. They should be able to find some extra BEES to run the tests on. Presumably they have access to a hive, at a minimum.

I agree a larger n would be nice (say, n=30 at least) and I *think* it's likely not too hard to obtain in this case. I would caution, however, that sometimes it's a lot harder than it looks to obtain these data. It could be that n=14 is hard to do.

I used to work in insect neuroscience and I collaborated with people who did experiments of the general sort described in the paper. The issue was of course not finding insects -- we had lots of insects -- the problem we had was that running the experiments was very time consuming and could often fail for unclear reasons. You may get drift in behavioral scores over time, batches of insects that produce suspect results, etc. All sorts of really weird stuff happens with animal behavior and so to get solid results you believe in might require throwing out most of your data (e.g. because variance was weirdly high on some days). After all is said and done your sample size isn't always what you hope for. I've seen really good people work for years and still end up with sample size of less than 10 animals.

Memorization of the correct and incorrect answers is all that is needed for the described (too small of a sample size to be considered an) "experiment".

How far /. has fallen...

It is true that memorisation could explain this. You point about the sample size is trickier, though. Firstly there is no magic number that constitutes a large (vs small) sample size. What is suitable depends on the size of the effect, the variance, and the degree to which you want to generalise the results to a wider population. This is often balanced against what is possible. In biology a lot of experiments have a small sample size because of the cost or difficulty in gathering the data. For instance, I just reviewed a paper where the authors have gathered data from just a single subject. However, they gather a vast amount and do a very thorough job. Their work still stands as it is (it's in a sense a methods paper) and given that they aren't targetting a big name journal or over-selling their results I'm going to let the n=1 slide.

In the particular case of this paper, what I find most annoying isn't the n=14 but that their graphs hide the underlying data by displaying them as just bars with a 95% confidence interval for the mean. I would also agree, however, that I don't see why in this case they couldn't have produced a larger sample size. That's not the main issue, IMHO, however.
