“Equal contribution” statements don’t mean much: Nobel prize edition

This is not a post about the Nobel prizes. It is a post about authorship.

The Nobel Prize for chemistry was given two people for protein folding. I told students in my introductory biology classes for years that whoever could solve that problem should book a ticket to Stockholm, because it would get a Nobel, and I’m pleased to see I was right on that count.

On Bluesky, Michael Hoffman pointed out that the key paper about AlphaFold has an equal contribution statement:

(T)he AlphaFold paper has 19 authors who “contributed equally” but only two of them (Demis Hassabis and John M. Jumper - ZF) get part of the Nobel Prize 🤔 

So why those two people out of all the 19 who made, allegedly, equal contributions? The paper has a “Contributions” statement:

J.J. and D.H. led the research.

I don’t think there has ever been a clearer demonstration that “equal contribution” statements don’t mean much of anything except to maybe the people involved. And their relatives.

Also worth noting that in the 19 equal contributions were, I believe, two women. (Guess based on given names, which is not ideal, I know. Still.)

More generally, authorship is a terrible way of assigning credit. I have, and will continue to, argue that the CRediT system of identifying specific contributions should be adopted just across the board.
