reciprocity is the best long term strategy

tit-for-tat
four lines of simple code

simple in its design
symmetric in its delivery

consider
begin with cooperation
then mirror the action
if the action is negative = punishment
if the action is positive = reward

loop

but always
begin with cooperation

so
give benefit of the doubt
to all new interactions
seek to provide something of value
in the beginning
create the need to reciprocate
whatever they do
respond accordingly
because actions should be punished or rewarded

consistency is key to collaboration
