The Keys to Gaining Adoption of Innovations.
Education (information dissemination) is a necessary, but not sufficient factor of adoption.• People are understandably skeptical at first.• Opponents will disseminate negative information.• Negative information carries disproportionate weight in the short run.
Persuasion by opinion leaders can overcome skepticism and the negative inputs of opponents.• Opinion leaders are respected, outside agencies with no perceived
vested interest in the innovation.

The Diffusion Effect.
Persuasion by Opinion Leaders.• Opinion leader adoption deems the innovation as “ok.”• The new idea/practice becomes socially acceptable.
Persuasion by Group Influence.• As more and more persons adopt, social pressure builds for others to
adopt.• What once was “deviant” becomes “expected.”
