I've downvoted: it's not clear to me why an infodump of the first 10 pages of the "Science of relationships" blog (and their first page of facebook content) is useful as a discussion post here. Although you have edited it (to drop mention of studies that don't meet your standards) - what's missing is any other organisation or analysis of the content reported there.

The content area is certainly relevant for LW, I just don't see the value added in presenting this information in this format.
