This thesis (which can be seen as a borrowing of the tipping point notion implicit in Lewin's tension system formulation long before Gladwell, 2000, popularized the phrase in the title of his best-selling book) has recently been given a successful empirical test by Keizer, Lindenderg, and Steg 2008, who demonstrated the phenomenon of “cross norm” violation, that is, disorder and non-lawfulness in one domain (e.g., graffiti or littering) resulting in increased violation (e.g., trespassing or even mail theft) in another.
