Lukewarm feelings about Mendeley by the way: http://stevepowell.blot.im/131/a-pdf-workflow-which-kills-no-kittens
I am an independent researcher based in Sarajevo.
I am interested in how we know the things we need to know to make our world work. Whether that is being a parent or running an NGO or running a country. You might say what we need is social evidence - evidence which is social in two senses of the word. First, evidence for how things are and how things change in society. Second, evidence which is itself social in nature, involving opinions, prejudices, values, memes, rumours, networks.
I find a good first move when trying to establish social evidence is to identify "mechanisms" or "programme logic" which might explain what is going on, even though these mechanisms might be vague and imprecise. If I can, I use visuals to collect and process these ideas. Pencil and eraser wherever possible.
