Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

It turns out "delve" is used more since ChatGPT indeed. How much of it is strategic use? www.theverge.com/openai/68674...

Credit statements are useful ex-post, but may create wrong incentives ex-ante and backfire. I think each author should vouch for the whole paper, encouraging mutual control. Credit statements compartmentalize responsibility, reduce mutual control and costs to collaborate with untrustworthy others.
