My editorial approach has always been pretty simple:
1. Is this a good research question?
2. Has an appropriate method been used to answer it?
And that is about it.

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.

Edtech company Chegg has filed a lawsuit against Google and its owner Alphabet, alleging that the search giant’s #AI Overviews hurt its online traffic. According to Chegg, the Overviews retain traffic that historically came to its website, “materially impacting” the company’s revenue and employees.
