really seems to be weak. There is no contradiction at all in what I said.
1.) If you believe in Socionics you also have to believe in subypes if you want to be logically consistent. It is obvious that some extraverts are more extraverted than others.
2.) If you believe in Socionics you may find subtypes useful or not. Some like to use subtypes, others don't.
Now where is the contradiction? I also believe in the existence of condoms - but I don't like to use them. Where is the contradiction?!
