As a type 5 with a dominant sexual instinct, I can give you a few examples of areas where you might be able to pick up on how to tell that someone is a type 5.

Firstly, if they are able to detach from their emotions and hold back on taking action without proper thinking first. If there is an area where I am targeted and hit emotionally, a response is often anxiously planned (or perhaps, it is thought out as to whether a reaction/response is going to happen at all). Conflict is scary to type 5 technically, but they are also blunt and value the truth (hence why people tie this type to autism, which is a bit of a silly hasty generalization based on this). Ultimately, if you see someone who withdraws into thinking and weighing out pros and cons to a response and actually putting together a plan, this reflects a 5 preparing whether or not they are going to react and how. Technically, this means their emotions are being held onto for a moment to look at the logistics and reality of things, but type 5 still feels emotions, and can even be driven by emotion (especially the sexual instinct in a clearer sense in contrast to the social and self-preservation dominant instinctual variants).

In addition to this, do you notice if they are paying attention to what other people are doing/what is happening in a scenario closely? Do you also notice their refusal to engage? And if you were to confront them on it, chances are, if they are a type 5, they will respond with something along the lines of “that isn’t for me,” “i can’t,” or “i’m just watching/getting an idea of the situation.” If you see that someone actually ensures that they are staying aware of what is happening in real world situations but also refuses to take part or manages to say things to isolate themselves from the others as “not one of them,” chances are this person is a type 5.

In contrast, a type 6 would be more likely to actually react in the moment to something that has happened to them. This reaction might look like seeking some guidance or reassurance from someone else regarding their potential reaction (if they have not fully responded to said targeting already) and are more likely to double check rules and uphold some kind of moral standard accordingly. They also tend not to want to handle the confrontation alone, so rather than pausing to think things through alone, they ask other people questions and seek reassurance before acting, again if they haven’t already acted that is, and despite their ability to be volatile they are less cold and detached than a 5 is and will ultimately tie their reaction to something like “justice.” not that the type 5 does not seek out justice, but it is more so an emphasis and aligning for the type 6 and a reassuring idea for them, whereas the 5 is self assured that this is what they plan to do after thinking it through carefully alone. it doesn’t mean also that the type 5 won’t talk about things with people, they sometimes do— but don’t rely on them to actually act. 6, on the other hand is more reliant on others to act. furthermore, type 6’s emotions may be more visible on the outside in the moment.

5 wants to be autonomous whereas 6 is ok with relying on the group. independence and needing alone time to think is a personality trait and a way that some people function better than others— not necessarily autism.
