projection is kind of throwing those thoughts / feelings etc out onto another person (not me! you!)

projective identification is when the person on the receiving end catches what is thrown and responds / behaves in a complimentary way.

there was a definition of projective identification from the link i posted.

i do it a lot...

that phenomena is meant to capture what can be 'manipulative' about some peoples emotions and the like... that the things we throw out there onto others can quite often provoke / prompt them to play a certain role.

e.g.,

rescuer...
persecutor...
victim...

and so on...
