PIVOTAL PREDICTIONS
In the Megatrends network, the significance of each prediction was determined by its positional properties. The definition of relative causal influence was a qualitative one, inching toward the quantitative.
A prediction that was directly connected to several others usually occupied a nexus or intersection of the network where causal influences both converged and diverged. (Carley, 1997) The number of links indicated the relative weight it played in the authors' thinking about the future. It was a “core concept” (Campos and Gaspar, 1995) if it occurred in several different chains of argument.
The following eleven predictions in Florida's Megatrends were directly linked to at least four other predictions in the network.
 Budget gap will widen between revenue and public needs.
 Cash-strapped communities will cut back on services and facilities.
 State and local governments will underfund education, health care and social services.
 Florida will continue to attract large numbers of immigrants.
 Florida's legislature will reexamine the state's tax structure.
 Elected officials will respond to political pressure from older voters.
 International trade and commerce will become more important to the economy.
 Political priorities of whites will conflict with those of minorities.
 Senior population will begin to explode by 2010.
 Seniors will demand better eldercare.
 Urban sprawl will continue to encroach upon rural and semi-rural areas.
These eleven were directly linked to about half of the other predictions in the Megatrends network. By expanding this list to include predictions linked to at least three others, more than 80 percent of all predictions were reached. There was a strong connectivity running through Megatrends; only a few predictions fell outside the several clusters of densely interlinked predictions that dominated the network structure.
