Syn-flow: sp → so → sx → sp
Stackings involved: sp/so → so/sx → sx/sp → sp/so
Direction: Compelled toward people. Acting upon and with others as a born insider i.e.- deeply human.
Contra-flow: sp → sx → so → sp
Stackings involved: sp/sx → sx/so → so/sp → sp/sx
Direction: Compelled against people. Seething belligerent outsiders; 'antisocial', provoking, reverse-flow change catalysts. In some profound sense, rejecting the human condition, their own and/or that of others.
It has been suggested that people with stackings that are part of same flow progression generally have more understanding and smoother interaction because they are channeling their energies in the same direction. Interactions of stackings that are part of the same flow have the potential to cover for one's blindspot instinct as well as reinforce one's own instinctual energy flow. For example: if one person's stacking is sx/sp, this person is directing energy in the following manner sx->sp->so, in which case another person with sp/so stacking will be reinforcing to their weaker secondary sp->so link and covering their SO-last blind spot. On the other hand interactions with people who are channeling their energies in the opposite direction can feel draining, dull, and disorienting in the long term.
