A lot of us have said that there’s been a dumbing down in JW land. It’s just not like it used to be – especially a few decades ago. It seems to me that if JW are right and the end of the world is near, the spiritual food should get tastier and more nourishing as time goes on, but it's getting more and more bland and less nourishing. The material was deeper a few decades ago. There were the Babylon book and all the 384-page prophecy books and deeper Watchtower articles. We realize now that it was BS, but at least it felt more scholarly and it did stimulate the mind and require some actual thinking.
So what happened? Why the change? Well, I think one reason has to do with the change in power structure of the org. It used to be that Freddy could hole himself up in isolation and come up with all the theology (including his types and antitypes) and there was nobody to check him; what he said was it. So it was easier to get the deeper material out at that time – because basically only one person had to approve of it – Freddy himself. He was the guru – the oracle – the sage - the scholar – the theologian, and I think the others felt too insecure to challenge him.
Now, though, if one GB member comes up some doctrinal point, that point has to have the vote of at least a majority of the other GB members, so it’s not as easy to get material out now. It’s sort of like a dictatorship or pure monarchy versus a democracy. Dictatorships and pure monarchies can enact laws, change laws, etc. quicker than democracies because in democracies such actions have to be approved by more people and that takes time and often kills the action because it’s not approved by the necessary entities.
So, now, it would be hard to have, for example, another Babylon book because it would have to be approved by too many different individuals and it just probably wouldn’t happen. At least the process would get bogged down and take far too long.
There are no more gurus or oracles; those days are over. JWs are in for a boring, dumbed-down ride.
(I think there are other reasons, too. For example, JWs just don’t have the brain power and scholarship. Also, with the availability of info now and all their failed doctrine, they have to be more careful, so the material has to be more elementary. They can't be as bold as they used to be; they know there's a good chance they'll get challenged.)
