From extended observations on mobs, animals and villagers alike, all prefer selecting 'north west' (if you live in the northern hemisphere) wandering directions. Whether in a pen, or on an island, or as part of a village, within a cavern, or what have you.
This seems to be a preference in direction, or an absence of preference in the south east, for all common AI wandering behavior. Clearly this behavior was meant to select an apparent random direction.
Computer science tells us 'random' is rarely truly random; and in this case, the technique employed may require further testing to confirm proper results.
Most recently observed in a village: all villagers dispersed evenly upon discovery, and by the fifth day, all villagers in the north west region.
