So looking through old emails I found a copy of this, which I sent to my then employer about their decision to ask us all to participate in a an MBTI test as part of a team-building exercise.
Having read about, and discussed this with people in the past, and come to the conclusion it is a load of old rubbish, I was naturally slightly disappointed, and disinclined to participate.
I thought my response was interesting enough to share here with people, so here it is.
Note. The company name has obviously been removed - but they were very understanding of my position - though no doubt felt I was making a big fuss about nothing and went ahead anyway - without me of course. Also, the last sentence is meant as an ironic joke... just in case you thought I was being hypocritical.
