This morning I was thinking about how sometimes each type can sometimes resemble their contrary type.
I had remembered reading something about this in Rebel's article (at the bottom)- Behaviours of Temperaments (socionics.com)
I've copied what he said below.
I remembered him saying we can act like a different temperament when in stress mode but only just spotted the bit about 'in downtime'. That's so interesting to me. I think that is part of the appeal of some of the types for me- is that every now and again they act like their contrary type, a type I might admire but not typically spend much time around. E.g In an Esfp I will sometimes see flashes of SEI. With particular types it might be more noticeable/ appealing. Not sure how it works with dual partners for example.
Rebel doesn't mention contrary types..but he does mention EPs acting like IPs etc.
Temporary Changes in Temperament
The above descriptions are certainly not exhaustive. It should also be noted that when under excessive stress and sometimes in downtime, the observer temperament will behave like an experimenter and vice versa, while leaders will behave like a planners and vice versa. This is because the psyche will attempt to change its reference perspective (from externalized to internalized, or vice versa) in an attempt to find solutions that have eluded them. However, temperaments never change their objectives and remain either input or output oriented.
