Quotes by Morten Jerven:
Statistics is the archetypal way of generalising from complex social realities to a very orderly aggregate picture – Morten Jerven
Make everything count. If you write something, make sure it’s going somewhere. If you prepare a lecture to speak about something, make sure you have an idea about how that can become a publishable unit – Morten Jerven
Make sure, as an academic working, it’s important not to think that working long hours is the key to being effective. Start writing early. It’s important – Morten Jerven
