Cooperation without dependence requires everyone’s contribution to be immediately detectable

Evidence

There are, of course, ventures that would naturally be called ‘cooperation’ but do not fall under this definition, because everyone in them is under the immediate control of everyone: if a party does not do his bit, this can be immediately detected. These are of no interest to the present discussion, which entirely concerns cases in which one party depends on another. — Diego Gambetta, Trust - Making and Breaking Cooperative…, 151
