Great that you noticed the proximity of the annual meeting timed to coincide with the WT Study.
I wanted to add that " I Feel" that the following video explains why the timing is so close.
Things that are hard to accept, such as the "new light" being turned on in this WT study will be easier to swallow if it is being discussed in the "presence" of others that believe the same way. It would be impossible to get ALL the jws together in one place so they do the next best thing that being to tie them in together via video so the attendees "feel" that they are certainly privileged to be a part of the revealing of the "new light"
I think that just the mind set of being "tied into the main feed, live" gives them feeling of comraderie.
If you check out this video showing the Soloman Asche study it will explain how just being in the presence of others, peers, it promotes one to put away any doubts they may be starting to experience.
When you watch the video, think of the "lone subject" as being a person at this "video tie in" that may be starting to have a hard time believing what they are hearing.
There is a little twist to consider and that is that although the Jws will not hear the "new light" coming from the other Jws, the head knodding in agreement, clapping, excited conversations afterward between the other Jws helps promote the thought from the doubting one that " maybe it is me tht is wrong in my thought, how can all these other Jws be wrong, it must be me that is having a hard time accepting it"
