Researchers in Quaternary sciences!

I’m running a short anonymous survey on how maths & stats are used (and taught) in our field — with a focus on methodology, publishing, and ethics.

It won’t take long — and your input would really help!

Sorry but, scientists need more time to live

Getting ready to present my new work on numbers and mathematics using Hieroglyphs in the 2025 QUANTA workshop in Bordeaux #ERC #QUANTA

But that doesn’t mean people can exploit preprint services to force their opinions on others as though they are established science. That’s not how this works.

[Lloyd A Courtenay @LACourtenay]

At what point does circulating an email chain and publicizing an unreviewed preprint as though it were established fact stop being ethical and professional?

[Lloyd A Courtenay @LACourtenay]

If my own papers are criticized, I’m fine with that. Nobody is perfect, and scientific progress depends on debate and scrutiny.

[Lloyd A Courtenay @LACourtenay]

@BrianaPobiner @SAAorg @SAfAarchaeology I still can't believe this is a thing... Is it true? I cant submit almost anything with such a rule, unless we start wars between supervisors, colaborators, and phds, thats going to make everything very complicated for many people!

[Lloyd A Courtenay @LACourtenay]

Just a final addition... this paper will probably tread on some toes, and cause some colateral dammage for which I apologise, but for science to evolve we need critical thinking!

[Lloyd A Courtenay @LACourtenay]

This week our new paper has come out demanding a more rigorous assessment of the use of DL-based Computer Vision in taphonomy with Nicolas Vanderesse @LucDoyon1 and @AntoineSouron ! @ERC_Research #QUANTA #abuseandmisuseofAI

[Lloyd A Courtenay @LACourtenay]

Finally, we wish to point out that this debate and dialogue is necessary for all types of research in archaeology using ML and DL (including my own!). We need to begin facing the facts that we have some serious limitations, and begin working towards solutions!
