Comment Re:Retraction != Fraud (Score 1) 229

Peer reviewers can't check everything, especially when the conclusion results from elaborate analysis of data from complex apparatus. Sometimes you detect bonehead mistakes, but usually your focus is more on clarity than correctness: do the authors explain their methods and reasoning in enough detail that someone else can repeat the research?

Yes, I agree with you here about referee's role, but not about authors role. It is necessary but not sufficient to explain methodology so anybody could repeat it. It is necessary also that if repeated the measurement from the paper, the same results are obtained. The one of many reasons is also so that other people do not have to repeat often expensive measurements.

But this is not fraud, and perhaps it's even healthy. Better to get crazy results out there than bury them in notebooks: sometimes they turn out to be major discoveries.

So for instance, when some not sufficiently checked results for medical treatments get published, you'd say that this is perhaps healthy?

Absolutely yes! It is the physician's responsibility to avoid basing treatments on results that haven't been independently confirmed. It is the researcher's responsibility to publish: how else will you get that independent confirmation?

In science there is no such thing as "independent confirmation". The whole point of publishing an academic scientific paper is to have an independently obtained results that are claimed in the paper. Imagine only that we have to "independently check" results obtained in particle accelerators.

Recall how the "neutrinos faster than speed of light" claim ended: not by imaginary independent checks but by finding the error in measurement, which, among other things, saved work and money of people to further the research in the direction that is now very likely would have led nowhere. If someone is still crazy enough to study speed of neutrinos in order to prove that they are faster than light and then finds that they are indeed faster than light, well that still would not make the previous measurements correct.
How about claims? Would that not confirm at least the claims of the former paper? Yes, but the science is not about claiming claims.

Other researchers need to know what they should attempt to confirm or falsify.

I disagree, and this has to do also with the referee's role: one of the reason the referees are not supposed to confirm or falsify results of the paper they refer is exactly because it is understood and expected that the authors have tried to do so themselves, to the extent that the field is requiring.

We're talking about the science of the journals here. This is raw "source code", checked to some degree, but not debugged. The debugging takes place in the community: if you don't publish, your results will never get properly debugged.

So from my responses so far now is hopefully crystal clear why your approach to doing science and the view of the role of scientific journals is not only non-scientific, but also socially dangerous.

I suspect it means "number of retractions" is a poor measurement of "rate of scientific fraud".

It is nevertheless a measurement of bad science. If I retract a paper because I spotted after publication an honest error that invalidates the claims I make in the paper, I am honest but still doing bad science.

The little graph accompanying the article itself shows that only about 1/3 or less of the retractions are "fraud" related.

No, the article does not say "fraud" related, but fraud related, and on the rise as well.

Increases in fraud retractions could be just the result of increased scrutiny, or increased transparency - maybe fraud itself is on the decline.

Since nobody measured "fraud itself", we don't know about its level, so, yes, you can formulate any hypothesis here you'd like: maybe it declines, unless it is on the rise. Given what the authors find, the first hypothesis is suspicious. Or maybe fraud is systemic, when the "true" trend wouldn't mean much even if we knew it.

In my experience as a scientist, what has increased is the pressure to publish quickly. So, people publish results that haven't been checked as much as they perhaps should be.

In some sciences there is so-called peer-review process. So it seems to me that scientists you mention who publish not thoroughly checked papers point also to the failure of the journals you don't mention to do at least semi-decent peer-reviewing process.

But this is not fraud, and perhaps it's even healthy. Better to get crazy results out there than bury them in notebooks: sometimes they turn out to be major discoveries.

Increasingly we're seeing lots of legacy code (C / C++ / Fortran) wrapped in Python.

That does not make sense, you are just confused.

OP is correct and it seems YOU are confused. A huge portion of the python libraries are just wrappers for fortran/c/c++ libraries. Pretty much every useful Fortran/C/C++ library out there has a python wrapper! For those that don't, tools like swig and cython make it trivial. I can usually wrap a fairly complex library in less than an hour.

People using Python for simplicity and expressiveness, dropping to C , etc. for the heavy lifting.

You mean they use Python to express themselves and C and FORTRAN to program?

Again, you are an idiot, and the OP is correct. You write all of the tedious bullshit in python. This takes a small fraction of the code/time that it would take to implement in C. You then identify the areas that need speed and either develop a C library, or just use some of the nice feature in cython. The end product is an application that took WAY LESS TIME to develop, and runs at practically the same speed.

This is especially true in the sciences (in HPC, for example).

You do know what HPC mean, right?

I DO! Part of my work is in HPC. Python is easily the fastest growing language in the field. Again, users can take decades of C and Fortran legacy code and effortlessly upgrade to the ease-of-use/rapid development of python without really sacrificing any performance. Furthermore libraries like numpy, scipy, matplotlib, guiqwt, pyfftw, pycuda, mpi4py etc. etc. make developing new HPC applications easy.

[emphasis in bold added]

Dear Anonymous Coward,

I'm glad to hear that Python lets you express yourself so eloquently!

Wish you a many successful HPC wrappings [after] writing "tedious bullshit".

The difference between a theory and a law isn't how verifiable a law is, but that theories attempt to explain why and laws do not. There is no explanation of why certain things happen in math and physics, so we have lots of laws in it. However, biology is far more abstract from fundamental truths of the universe, so it tends to have theories, since what is tested has explanations. Psychology is even more abstract, and thus would be even further down that line.

Abstraction in sciences is generally understood as a way of simplifying things--physics and chemistry are more abstract than biology and psychology because they employ simpler concept like particles, forces, atoms compared to cells or emotions. You conflate explanation, theory and law, with result being a sort of typical soft vs hard science confusion (also when you say "further down that line" What line?)

Submission + - Discouraging Playstation Vita Details (itworld.com)

itwbennett writes: "Sony's new handheld gaming system, the Playstation Vita, launches in Japan in two weeks, and the latest report from Andriasang has some interesting details, including Sony's decision to go with proprietary memory cards. Sony says this is both for security reasons and to ensure a consistent experience for all users, but that 'doesn't explain why they're charging such enormous sums for these cards,' says blogger Peter Smith. 'The caveat here is that we haven't seen official pricing for the cards, but game retailer Gamestop lists them at $120 (!!) for a 32 GB card, $70 for a 16GB, $45 for 8 GB and $30 for a 4 GB.'"
