The most influential authorship guidelines are those of the International Committee of Medical Journal Editors, and they require all co-authors to contribute to the writing of a paper reporting a project. Just doing all the non-writing work for the project is not sufficient for co-authorship! 🤔

Rossiter coined the term "Matilda effect" for when women's scientific work is attributed to men.
It was a twist on the "Matthew effect," famously attributed to Robert Merton, but actually studied jointly by Merton and his wife Harriet Zuckerman, who was denied co-authorship

Different disciplines handle the division of labor between theory and experiment. Some fields have dedicated theoreticians who hardly ever do experiments (and vice versa). Others divide it less strongly or not at all.
