Some JW 'facts':
Jehovah created everything
The Bible was written under inspiration of Jehovah
The JW org leadership is the mediator between humans and Jehovah
If you believe and do what the GB tell you; you will live forever in paradise
Note that the above beliefs have no chance of being proved and this is why religious doctrine is of no scientific or practical value. How can anyone seriously say "God is love" when there is no God willing to show itself in the first place? God only exists in the collective imagination of believers, and most of them were taught to believe so from infancy.
Religious belief only has value for the individuals who require hope beyond hope that a magic world exists somewhere. You cannot make any further developments from such elusive and slippery dogma.
By contrast a good example of the thoroughness required by scientific progress is seen in medical practice. Here exhaustive and critically appraised test evidence, including blind trials, is vital before we start using new medicines.
Why not use the same rigorous and factual "evidence based testing" for religion?
