Instinctual variants was one of the last things I learned regarding personality theory: Socionics - the16types.info - Instinctual Stackings For the longest time, I didn't understand them or put much emphasis on how it impacts someone's personality. What I've come to realize is the impact is often in how we interact, and influences behavior quite a bit. For example, I run a discord server with hundreds of members. There, we assign people roles based on their type. The breakdown is probably 70-80 very active users, 120-150 semi active, 150 rare posters, and 200+ never posters. Now, there's a variety of reasons for this, but one of the strongest correlations I've found is the social instinct. So/sx types through themselves in the most while sp/sx are the least likely to get involved.Same theory on personalitycafe like when I do the invasion threads. Social and Sexual see the purpose, while SP is less likely to get involved. I've also noticed that sp inferior is more likely to willingly share personal information online, like a photo, first name, or location, while sx/so is probably the most likely.These variants effect how someone interacts within a group. so/sx tends to be more superficially involved with everyone. sx/sp, would look for a couple of people to bond with and don't care as much for the group dynamics. I encourage people to read about how it influences our type as it can explain things that MBTI/Enneagram does not. This is just an intro, but I've love to discuss how people feel it influences their type.
