Strength of weak ties

23 March 2009

Right hand figure: two networks joined “loosely” by a single person, only slighetly engaged with either network.  Was said to be a Prof. who sat on both communities [and therefore knew what both were doing] but did not really engage in their work.

Those people able to stimulate innovation have lots of WEAK ties which join communities. — This is the “strength of weak ties” principle.

The 1954 study is meant to be in Roger’s Diffusion of Innovations book…

Although this guy says 1954, everyone else seems to be citing a 1966 Colemand, Katz and Menzel paper:

Coleman, J.S., E. Katz and H. Menzel (1966) Medical Innovation: A Diffusion Study.  The Bobby-Merrill, New York.

This (looks good): http://www.infoamerica.org/documentos_pdf/difusion_teoria.pdf

suggests there are three early Coleman et al papers, none of which were in 1954:

Coleman, James S.; Katz, Elihu & Menzel, Herbert. (1957).  The diffusion
of an innovation among physicians.  Sociometry 20: 253-270.

Coleman, James S.; Katz, Elihu & Menzel, Herbert. (1959). Social processes
in physicians’ adoption of a new drug. Journal of Chronic Diseases. 9: 1-19.

Coleman, James S.; Katz, Elihu & Menzel, Herbert. (1966). Medical
Innovation: A Diffusion Study. New York: Bobbs-Merrill.

there was a “movement” from 1954-1957, however.

What is “Granovetter Transitivity”??? Seems critical.

Main influence on trust [from prior] is honesty / reliability.

Lots of stuff out there on trust – could stranger—familiar continum be a basic starting point??

Andrew Whitworth – University of Manchester – gave the SNA / Innovation within Organisations presentation at the Vision conference on Firday. Knew what he was on about… Lots of insights into the implications of networks, rather than merely focusing on their structure. Main point was the “importance of weak ties” between cliques/networks within a broader context. It is these that spread insights between communities of practice from which innovation results. But how does this impact trust (which we want to look at)???
