[Sociological Theory, Volume 1 (1983), 201-233.]
In this chapter I review empirical studies directly testing the
hypotheses of my 1973 paper “The Strength of Weak Ties”
(hereafter “SWT”) and work that elaborates those hypotheses
theoretically or uses them to suggest new empirical
research not discussed in my original formulation. Along
the way, I will reconsider various aspects of the theoretical
argument, attempt to plug some holes, and broaden its
base.
