Hey Mr Flaneur
I think you've grasped the wrong end of the hammer mate : )
Sorry just a joke
These articles are focussing on physical and technical training for indoor wall users that also go outdoors climbing trad/sport/bouldering. These articles are designed to help climbers use the wall most efficiently to aid them in improving.
Yes these articles put E1/2 at the top, but imagine that as a technical/physical level and less at a... how would you say... "How to use tools effectively" level? I'm not teaching people how to place gear or how to overcome fears for Trad, only "how to train to become a better climber" as the title suggests.
You could argue that these articles might encourage technical and physical development over social/psychological as you put it, but I never intended that nor have I said anywhere that the other issues weren't important as well. But you can't disregard the fact that being stronger/fitter/better at climbing isn't going to improve your trad grade.
And like JLS said, you will become more confident by becoming a better climber in turn which I suppose you could say is fulfilling a few of those psychological/social issues you mentioned.
Hope this clarifies things
I hope there's not too many screws loose aboot this hoos : P
