People used to take socionics a lot more seriously than what they do now, a lot of the things people said were not particularly true and although perhaps looked good on a theoretical level, it didn't work because the premise = socionics explained everything, lead to logic errors (it did not work in real life).

If you are looking for a socionics forum where everyone is a 100% believer and there are no humour or distraction posts or deviation from group thinking then this isn't the forum for you @Wacey. Alternatively you could go on a crusade and pull up everyone who says something you happen to disagree with - this is how some members ended up leaving because they got sick of it (in part this is why @Phaedrus left, Bolt). I don't know for others, they maybe just got busy with work life and realised some things about socionics.
