I haven't read through the site to see what is there, but software engineering methodology and technique research* uses techniques from research of management techniques in business, making it closer to psychology or sociology. For more information, the blog "It Will Never Work in Theory" does a good job of highlighting these sorts of results that are directly useful and has some explanation of the tools they are using to study software engineering practices. The book Making Software goes into much more detail on software engineering research methodologies if you are interested.
*As opposed to CS theory research that could be used in software engineering, which is usually math.
The Halo Effect  amped up my skepticism. Of course it was a business book  that introduced me to the Halo Effect... :-)
