Although the impacts of chance occurrences play an important role in s
ome of our everyday narratives, they are rarely discussed in social sc
ience accounts of the life cycle. The discrepancy between chance's rel
ative significance in each of these portrayals is partly attributable
to the highlighting of the unusual and unexpected in order to make our
narratives interesting. The difference is also based in social scienc
es' attempt to tame chance using stochastic models enriched by recent
nonlinear dynamic systems approaches. A critical factor affecting our
accounts, whether in everyday life or in the search for robust general
laws of behavior, is our commitment to prediction and control.
