Ij-processing really needs 'autonomy' to be effective similar to Ep although 'freedom' is more it's need; there's a nuanced difference between the two requirements.

Now, Ip-processing seems to be based around maintaining various forms of 'security' and they tend to be the less likely to invade or start something although they will defend vigorously. Ejs usually thrive by invading the space of others, although they tend to resist invasion when others do it to them or when they have no 'control' over the agenda. All temperaments will resist invasion in their own ways for different reasons; it seems to be an essential aspect of ego.....
