Similar to the stress and security points thread, you evolve into your lookalike/business partner when secure (dualizing) and degrade into your contrary/extinguishment partner when insecure (undualized or separating from dual). At a middle point, you are your type.
Why these types? I figure the more secure you are, the more energy you having running through the entire IM system, and therefore the more you have for your superego block, which is usually too draining to use for long. But you resemble your lookalike partner more than your superego partner, because the creative function is still valued over the polr. Likewise when you are under stress, there is less energy going around, so you revert back to the efficient id block and resemble your contrary partner.
