One of the basic situationist practices is the dérive [literally: “drifting”], a technique of rapid passage through varied ambiances. Dérives involve playful-constructive behavior and awareness of psychogeographical effects, and are thus quite different from the classic notions of journey or stroll.
If chance plays an important role in dérives this is because the methodology of psychogeographical observation is still in its infancy. But the action of chance is naturally conservative and in a new setting tends to reduce everything to habit or to an alternation between a limited number of variants. Progress means breaking through fields where chance holds sway by creating new conditions more favorable to our purposes. We can say, then, that the randomness of a dérive is fundamentally different from that of the stroll, but also that the first psychogeographical attractions discovered by dérivers may tend to fixate them around new habitual axes, to which they will constantly be drawn back.
