The social sciences are probably the biggest branch of the topic tree. It has already subdivided into four branches. You can find those branches below the Social Sciences tab. What this means is that I get to decide which branch best fits your topics if you submit them through the Add-a-Topic page. The three branches include: psychology, anthropology, sociology, economics/business, and more. If you think any of this is dry and dull, remember that any popular topic or interest can be given an "academic twist" by viewing it as a social science. Also many mental health/medical topics are also psychology topics.
