If you have a strong grip on exactly what it means, sure, but look at any HN thread on the topic of fraud in science. People think replication = validity because it's been described as the replication crisis for the last 15 years. And that's the best case!
Funding replication studies in the current environment would just lead to lots of invalid papers being promoted as "fully replicated" and people would be fooled even harder than they already are. There's got to be a fix for the underlying quality issues before replication becomes the next best thing to do.
> look at any HN thread on the topic of fraud in science.
HN is very tedious/lazy when it comes to science criticism -- very much agree with you on this.
My only point is replication is necessary to establish validity, even if it is not sufficient. Whether it gives a scientist a false sense of security doesn't change the math of sampling.
I also agree with you on quality issues. I think alternative investment strategies (other than project grants) would be a useful step for reducing perverse incentives, for example. But there's a lot of things science could do.
while i agree that "reproducibility is overrated", i went ahead and read your medium post. my feedback to you is, my summary of that writing: "mike_hearn's take on policy-adjacent writing conducted by public health officials and published in journals that interacted with mike_hearn's valid and common but nonetheless subjective political dispute about COVID-19."
i don't know how any of that writing generalizes to other parts of academic research. i mean, i know that you say it does, but i don't think it does. what exactly do you think most academic research institutions and the federal government spend money on? for example, wet lab research. you don't know anything about wet lab research. i think if you took a look at a typical e.g. basic science in immunology paper, built on top of mouse models, you would literally lose track of any of its meaning after the first paragraph, you would feed it into chatgpt, and you would struggle to understand the topic well enough to read another immunology paper, you would have an immense challenge talking about it with a researcher in the field. it would take weeks of reading. you have no medicine background, so you wouldn't understand the long horizon context of any of it. you wouldn't be able to "chatbot" your way into it, it would be a real education. so after all of that, would you still be able to write the conclusion you wrote in the medium post? i don't think so, because you would see that by many measures, you cannot generalize a froo-froo policy between "subjective political dispute about COVID-19" writing and wet lab research. you'd gain the wisdom to see that they're different things, and you lack the background, and you'd be much more narrow in what you'd say.
it doesn't even have to be in the particulars, it's just about wisdom. that is my feedback. you are at once saying that there is greater wisdom to be had in the organization and conduct of research, and then, you go and make the highly low wisdom move to generalize about all academic research. which you are obviously doing not because it makes sense to, you're a smart guy. but because you have some unknown beef with "academics" that stems from anger about valid, common but nonetheless subjective political disputes about COVID-19.
Thanks for reading it, or scan reading it maybe. Of the 18 papers discussed in the essay here's what they're about in order:
- Alzheimers
- Cancer
- Alzheimers
- Skin lesions (first paper discussed in the linked blog post)
- Epidemiology (COVID)
- Epidemiology (COVID, foot and mouth disease, Zika)
- Misinformation/bot studies
- More misinformation/bot studies
- Archaeology/history
- PCR testing (in general, discussion opens with testing of whooping cough)
- Psychology, twice (assuming you count "men would like to be more muscular" as a psych claim)
- Misinformation studies
- COVID (the highlighted errors in the paper are objective, not subjective)
- COVID (the highlighted errors are software bugs, i.e. objective)
- COVID (a fake replication report that didn't successfully replicate anything)
- Public health (from 2010)
- Social science
Your summary of this as being about a "valid and common but subjective political dispute" I don't agree is accurate. There's no politics involved in any of these discussions or problems, just bad science.
Immunology has the same issues as most other medical fields. Sure, there's also fraud that requires genuinely deep expertise to find, but there's plenty that doesn't. Here's a random immunology paper from a few days ago identified as having image duplications, Photoshopping of western blots, numerous irrelevant citations and weird sentence breaks all suggestive that the paper might have been entirely faked or at least partly generated by AI: https://pubpeer.com/publications/FE6C57F66429DE2A9B88FD245DD...
The authors reply, claiming the problems are just rank incompetence, and each time someone finds yet another problem with the paper leading to yet another apology and proclamation of incompetence. It's just another day on PubPeer, nothing special about this paper. I plucked it off the front page. Zero wet lab experience is needed to understand why the exact same image being presented as two different things in two different papers is a problem.
And as for other fields, they're often extremely shallow. I actually am an expert in bot detection but that doesn't help at all in detecting validity errors in social science papers, because they do things like define a bot as anyone who tweets five times after midnight from a smartphone. A 10 year old could notice that this isn't true.
it only takes one drop of talking about COVID to make it about politics haha
Part of replication is skeptical review. That's also part of the scientific method. If we're not doing thorough review and replication, we're not really doing science. It's a lot of faith in people incentivized to do sloppy or dishonest work.
Edit: I just read your article linked upthread. It was really good. I don't think we disagree except I say we need to attempt the steps of science wherever sensible and there's human/political problems trying to corrupt them. I try to seperately address those by changing hearts with the Gospel of Jesus Christ. (Cuz self-interest won't fix science.)
So, we need the replications. We also need to address whatever issues would pop up with them.
Yes, that's true. In theory, by the time it gets to the replication stage a paper has already been reviewed. In practice a replication is often the first time a paper is examined adversarially. There might be a useful form of hybrid here, like paying professional skeptics to review papers. The peer review concept academia works on is a very naive setup of the sort you'd expect given the prevailing ideology ("from each according to their ability, to each according to their needs"). Paying professionals to do it would be a good start, but only if there are consequences to a failed review, which there just aren't today.
