Do you think there are complimentary pairs? For example, is is likely that an 8 and a 2 will end up together because the other person is in the direction of the integration/disintigration arrows?
Is it healthy to have such a pairing? Let's take the 8 and the 2. Is is good for the 8 (because 2 is a good direction) and bad for the 2 (because 8 is a bad direction).
