Reading a thread about smoking the other day made me think......
Previously on this site (which I have spent much of today unsuccessfully trying to find) I recall reading that as numbers of Publishers declined at the end of WWII, the 'No Blood' doctrine was introduced in 1945 as a direct result in order to boost numbers again.
After the 1975 fiasco, I believe the Society lost a lot of followers - and it was very shortly after this (during the same or following year), that the WTBTS introduced the smoking ban. Again to boost flagging numbers?
When the WTBTS experience a 'failure', do they resort to introducing another doctrine, or is this just a coincidence?
