The approach is straight out of the Evolution of Cooperation by Robert Axelrod, first published 1984 and still going strong. Essentially it boils down to – don’t let a wrong go unpunished, be proportionate, don’t bear grudges or keep score, always go back to and signal willingness to cooperate – I prefer to call this reciprocity because of the unfortunate baggage that Tit-for-Tat has (vendettas, revenge, biblical eyes for eyes) which really do get in the way of this clear pragmatic (an in my personal experience) successful approach
