Re: Just 11% of 53 cancer research papers were reproducible
#102This is one of the reasons I went into math and software. In math there is only black and white, provably true and patently wrong. Still, part of the reason this is so is that to show any results everything must be laid on the table. CS and Math papers are therefore open by design and the world has benefited. I hope the rest of science will move in this direction.
This is an actually challenging problem. I don’t think running away from it and resorting to cheap tribalism is a great idea.

#103Truth is, they may have just gotten a funny little mutant of a cancer cell that happens to heavily express this one receptor as part of its unique mutated biology. For all we know a lot of cancer research has been about exploring the peculiarities of the genome of Henrietta Lacks.

#104I came to the biological sciences trained as a chemist. As I began working on my Ph.D. and variously encountered papers on cell signaling research (the field that much "cancer research" would fall into) it was blindingly apparent to me, perhaps because of my chemistry background, what was going on... Cell Signaling (and much of Biology) research is in its Alchemy phase. Now, alchemy often gets a bad rap as being comp…
>Cell Signaling will, eventually, have its Joseph Priestley, its Dmitri Mendeleev. That's very optimistic, but not necessarily true (even ignoring the question of when ). Priestley succeeded so well because he developed simple, reproducible experiments (expose mercury oxide to sunlight to produce oxygen etc.) that he was happy to share for no financial gain (even traveling to others' labs to help them reproduce his w…

#105After decades of publish-or-perish sweatshop science I'm sure the great shining archive of scientific truth is sort of like an inbox with no spam filter.
Such a powerful sentence. Lately science looks like olympic games without anti-doping control...

When we engineer things, it's one-part-one-function. Living systems are every-part-every-function network graphs with weighted edges that are subject to dynamic reconfiguration.
A cell isn't a computer that runs "code" in the form of DNA, nor is it a "machine" as we understand it. A "structured cloud of probabilistic quantum interactions among molecular nanomachines" is a bit more accurate.
Until we conquer these meta-problems, we won't understand the cell or the genome. I don't think they can be understood classically -- and I don't mean classically in the sense of omitting quantum mechanics. (Though that's true too.) I mean classically in the sense of linear fixed-relationship cause and effect machines.

> "those authors required them to sign an agreement that they would not disclose their findings about specific papers" I don't know why this doesn't cause a huge stir in the scientific community. Seems like everyone is fine with people sweeping their negative data under the rug. Shameful is a very mild word for that.
How were those authors able to enforce this request? To be a proper paper it should not be necessary to contact the author in order to reproduce it. If you had to ask the author for more details then their paper was incomplete - perhaps that's why it could not be reproduced.

> It's not that the results are completely invalid Especially if only 11% of them are reproducible, they're only 89% invalid. I'd go so far to say: If the reproducibility rate is 11%, you're not doing science, you're just pursuing funding.
You're assuming that only "reproducible" results are valid, which is incorrect. Results that are reproducible within a lab, but not when attempted by other people in different settings indicate that there's an unaccounted for variable, and that falls into the 89%. There's still something valuable there, it's just that we don't yet know all the variables. We could just give up, or we could try to continue study of som…
Re: Just 11% of 53 cancer research papers were reproducible
#110I work in biomedical research, and this finding has been discussed quite broadly. Most researchers don't believe it. Exactly reproducing novel findings usually requires a significant investment into the underlying procedures, which most places will not undertake. Reproduction instead usually occurs as part of an extension of the initial findings. The complexity of biology means that the first findings are frequently…
Really? Meaning that either there's another unaccounted variable(s) that controls the effect of A in B and C, meaning that we cannot conclude anything from the experiment. Yes and no is not acceptable...
All the people who use this law do so because their work is about some kind of model, which can be wholly known. However, if you have a misfortune of working in the real world - like nearly everyone - then you can't apply this law. This means that you won't ever get a proof in a mathematical sense. You won't ever be completely certain - you can be convinced beyond reasonable doubt, but that's all.
So when we talk about how biologists are just grant hunters because someone couldn't reproduce their experiments we need to take this into account. I don't know, but if I had to guess I'd say that nobody ever expected these experiments to be 100% accurate, 100% reproducible or 100% true. I think they are treated as a data point, some input to think of, and not definite truth.
But I may be completely wrong here, of course.
