I am not sure I have the energy for the torrent of abuse that comes with reporting the manipulated RC dating , which now seems to be the ONLY piece of information sceptics look at. But I will repeat it because it is Not just AN important paper, it is the ONLY important paper as far as sceptics are concerned.
And it was a piece of wilfully misleading junk!
1/ In 1989 Damon et al, published the supposed shroud RC dating in nature, based on 3 labs testing parts of one sample and giving a date range. Now that’s all sceptics ever talk about. The numbers were misrepresented as homogenous , statistically significant ,and established a 95% dating bound. But it was a fraud.
( now Lets ignore all the other controversy, about how the daters ignored all the protocols & a lot of red flags , or the fact the samples were different stuff from the shroud body , or the fact other information. makes those dates unlikely/ or impossible ….)
Let’s just stick to numbers…
2/ for years other researchers had tried to get hold of raw data and remnant samples from labs and met a stonewall. Van Haelst had already noted oddities in what they reported, which is why he requested it. It turns out halls of Oxford took it all home and into retirement. Dodging scrutiny?
3/ finally a researcher called Casabianca used legal force - an FOI- to get the results from the British museum.( Tite of the museum - you may recollect - was the one appointed to ensure good behaviour and to collect results for the final paper, but he had moved on, so the defences were down by then)
4/ imagine the consternation when it was revealed the numbers were fiddled and that all involved had been misleading the public!
To use the “ polite diplomatic” words of the paper I will now reference what they said : ( probably trying to avoid getting sued)
The figures
“showed that some of the original Shroud date measurements reported by the three laboratories to the British Museum were modified from their original ‘raw’ laboratory values and transformed into their published form using an unstated methodology.”
Such a polite way to say fiddled!

5/ The reality is the labs figures were not homogenous , so there was no date they could safely report ( the date is certainly void if done under GMP)
A truer reflection showed a big date gradient of 100 years a cm. That is not just a detail. It invalidates the test completely. It says either the process or samples are not consistent enough to date. (And it is entirely consistent with a repair of modern material (Rogers) , who detected cotton, a different type of linen& dye )and it also explains the Uv fluorescence.
The truth is of course fascinating. The AMS worked fine but the daters failed. So it would have wrecked the perceived reliability of AMS if they reported it. So they fudged it instead.
6/ It also says something about peer review. One of the reported standard deviations in nature didn’t even match the fiddled data. It was literally plucked out of thin air to make the published data homogenous. The reviewers missed it. I don’t blame them. But it proves peer review is not a catchall.
7/ It was tites job to make sure it all added up, but even an Italian stats lab that was supposed to check figures got ditched along with most of the protocol.
The protocols were argued for years in international meetings. The protocols safeguards , and red flags , including involvement of a stats lab were all ignored.
Did you know about the fiddle? Opdrey didn’t. Most sceptics don’t.
Are you happy with “unknown transforms from lab book to paper”? I am not.
Data does not “ transform itself” without “help” It wasted an entire decade.
If only they had either followed the protocol OR reported what they actually found. They did neither.
