Thanks for putting some realism in the thread. I've been a PhD student and the involvement of the lab head ranged from actually giving some research direction to doing jack shit depending on the paper and the people leading them. It was very obvious once when he green-lighted one of my paper for submission yet wanted to changed half of it when I made an internal presentation about it a week later. I challenged the thing one time to an intermediate supervisor (who where at least really contributing a bit) and I got bullshit excuses like "he's securing funding", "running the lab"... well at least not for my project since it costed nothing and I came with my own funding. At this point the toilet cleaning lady was contributing more to the paper because of how she allowed me to work in a clean environment. So I'm not surprised by Japan being over-represented like mentioned in the article. My lab explicit policy was "quantity over quality" written in a presentation given to new student. I know have a mental, logarithmic curve of contributions from authors: first made 90% of the work, second 9% and the following authors share the last 1%.
