Richard,
I think this numbers are a result of the recent doctrinal changes the Society stated in the Watchtower. At this moment many of these dicisions are to the person him/herself. The own responsibility lead to OWN DISCISIONS, with as result the numebers I read in the article.
Many of the younger JW-christians (me included) will take a more pragmatic position. Doctrinal we get more responsibility, so we take that responsibility, however it could have some consequences.
The Society says to the outside world "own responsibility" but for internal ears it has to be "follow us, there is nothing changed". Younger JW's read this between the lines and take their stand.
