Tangential to this article, but chance events which effect an individual's life circumstances tend to be subject to feedback loops, where more of the same become more likely, in the sense that someone in bad circumstances (possibly partly attributable to bad "luck") has an increased range and likelihood of events that could make those circumstances worse. Same story with beneficial events, mutatis mutandis.
