I've been on a singles holiday to spain with 21 people. As usual I was typing people according to socionics but I noticed groups were formed with another primary driver than socionics! Others noticed it also.

The groups were formed based on stackings. Sx people formed a group, they were loud, binge drink, and late for the excursions. The So people (I guess) who were completely satisfied by just talking and hanging out together constantly. Sp tended to be the outsiders, they left the group setting early to go to bed in time.

Almost no socionics matches were made, except when people were one on one.

So I wonder how much this stackings has an effect on intertype relationships, i tend to give it more weight now then before. What is your opinion? I want to learn more now I saw this happening.
