JW theology suggests that the work of gathering in the "144,000" has all but ended , particularly since 1935 , and that the number will inevitably diminish to nil. Indeed , some JWs maintain that all the anointed will have died and resurrected before Armageddon arrives. The Watchtower claims that the fact (?) that the number of genuine anointed is diminishing proves that the end is close. Half of every Memorial is spent telling the flock that there is only a very unlikely chance of anyone being anointed and that anyone who takes the emblems unworthily is guilty of a serious sin. Yet the number of those who claim to be anointed has flatlined at 8K - 9K for the last 20 years - indeed , in some years , it has actually increased. Why?
From a statistical point of view , essentially the number of "new" anointed only needs to be a tiny amount each year to maintain or grow the anointed figure. This is because the pool of possible anointed is taken from 7 million witnesses , plus over 250K who are baptised each year. Assuming about 100 anointed die each year , only 0.001% of JWs need to become anointed each year to maintain the overall figure , or about 1 in 70,000. Simply put , there only needs to be about 2 new anointed each year in a country as large as the UK to maintain the figure.
In reality there are far more than that. I know of at least 5 new anointed ones to my knowledge over the last 10 years. And my experience is that one anointed person invariably triggers off another one , from their close friends , associates and family members (especially husband and wife "anointings"). In other countries , the "hurdle" involved to becoming anointed is far less - a friend who is a missionary in Africa says that virtually all new JWs are convinced of their anointed status.
There are other factors at play here. Being anointed carrys a huge spiritual status in the Org. Most new JWs come from a Christian tradition which teaches them that they will live forever in heaven. And the "epiphany" of being anointed is a well documented unquantifiable psychological / religious experience in all cultures that affects 10% - 15% of all people. The reflex is suppressed in most vulnerable JWs , but inevitably some succumb.
Summary - the number of reported anointed will never decrease. I boldly predict a small increase this year.
