These two approaches are based in the works of John Bowlby.  They not "pop" psychology.  Each have several publications and are reputable therapuetic treatment approaches.  Each have a variety of articles and books clearly linking the approaches to Attachment Theory and John Bowlby.  They should stay...however, if you feel a poll would be useful to see what the consensus is, that would be a reasonable approach to follow before begining to edit the page...last time you were here you did create quite a problem and, if I read the history right, were asked to stop editing this page for a while. so, lets proceed reasonably and slowly and try to build consensus this time, ok.
