The New Republic has an interesting article linking the psychology of self-control to the issue of escaping poverty (with some delightful trolls in the comments section). Most people will recognise this field in psychology by the famous Marshmallow study, where the self-control of kids are put through a test of delayed gratification. I am a huge fan of these studies and have become far more excited now that these concepts are being tied to poverty reduction.
I won't delve too deeply into this as I believe the article is able to explain the whole idea a lot more eloquently. However, I would like to share some additional links to the excellent PsyBlog, that talks about a range of studies on the topic as well as some coping mechanisms to be taken advantage of. link, Link, LINK!
