Seeking elegant explanations for everyday social behaviour

While I was reading economist Tyler Cowen's new book "Discover Your Inner Economist", I suddenly had this crazy idea of starting a blog. I wanted to write about the things that I learned in school and try to apply to them to what we see in everyday social behaviour. As a student of Economics and Psychology, I'm quite fond of putting the two disciplines together whenever I can. I think many of my friends and fellow students at SMU agree with me that Economics assumes too much, especially the idea of rationality in human beings. Psychology can perhaps better reconcile theory and practice in this aspect. At the same time, I think the mathematical rigour of Economics can sometimes help to reinforce certain theories in Psychology (I will try to give examples later on).

Another reason why I wanted to start this is because I have developed a sceptical eye of what I read in the newspapers, especially the forum section where people give their views and opinions on things like parenting, sex, education etc. Not that I disagree with what is expressed, but I would just like to see a bit more scientific rigour to back up those arguments, as opposed to expression of mere feelings and attitudes.

Just a disclaimer to those who might take an interest in what I write. Although I might cite research articles and diligently ensure the accuracy of what is written, I am still just an undergraduate trying to make sense of what's happening around me. You should never take what I write at face value, but do your own research and form your own attitudes and values.
Lastly, I will appreciate all constructive criticisms and comments from anyone. If you feel that my arguments are not robust enough, or simply not accurate, please point them out. It will be a great learning experience for me.
