The replication problem is worse the less rigourous the field. The hoax authors managed to publish their first 7 articles, with 20 more still in review IIRC, over the span of 10 months. They were quite confident that the rest would have gone through had some journalists not prematurely unearthed their subterfuge.
For instance, in the dog park paper, the authors claimed that they had inspected the genitals of 10,000 unique dogs in a single dog park over a short time span, and then questioned the dog owners on their sexual orientation. If you can even look past the absurdity and take it seriously, the sample being analyzed is clearly biased in various ways. What dog park would have 10,000 unique dogs and owners visiting in such a time frame? How is this a representative sample? What sort of owners would be open to strangers fondling their pet's genitals and then questioning their sexuality?
Each paper had distinct and meaningful bias or clear cherry picking injected into the data, and not a single one of them was caught in review. The hoax authors have emphatically claimed that this field is more akin to theology than any kind of meaningful science, where any paper that reinforces the orthodoxy gets published, no matter the methodological flaws, and that's what they attempted to demonstrate (and they did I think). This result is far, far worse than the replication crisis.
> I'm assuming you're talking about the conclusion many have drawn - which I think is pretty uncontroversial - that science, logic and math are not fields free from bias.
No, I mean quite literally that these "academics" think that the scientific method, and that logic and mathematics itself, are tools of white oppression. I won't vouch for the rest of the site, but the description presented here is a decent introduction to the "reasoning" they employ: https://www.americanthinker.com/articles/2016/07/the_scienti...
Edit: or just google "the scientific method is oppressive" if you want to find further evidence. There are thousands of papers, articles, blogs and posts debating this claim. See: https://www.thecut.com/2017/04/the-science-march-sparked-a-b...
