The four personality types still missing after 36 submissions are:
INFJ:
INFJs tend to see helping others as their purpose in life, but while people with this personality type can be found engaging rescue efforts and doing charity work, their real passion is to get to the heart of the issue so that people need not be rescued at all.
5.9% of the population, around 1 per 17 people. So we should have two by now.
ESTJ:
ESTJs are classic images of the model citizen: they help their neighbors, uphold the law, and try to make sure that everyone participates in the communities and organizations they hold so dear.
7.1% of the population, around 1 per 14 people. So we should have two by now.
ESFJ:
At their hearts, ESFJ personalities are social creatures, and thrive on staying up to date with what their friends are doing.
8.6% of the population, around 1 per 12 people. So we should have three by now.
ISTP:
Rather than some sort of vision quest though, ISTPs are merely exploring the viability of a new interest when they make these seismic shifts.
3.1% of the population, around 1 per 32 people. So we should have one by now.
It feels like it is because these people are so nice, that they are being kept captive...
Or maybe they just don't like forums very much
It would be interesting to know what personality types the active JWs who wont give up their believes no matter what, are.
