Public knowledge, public trust: understanding the 'knowledge deficit'

Area of Science:

• Social Sciences
• Science and Technology Studies
• Public Policy

Background:

• The 'knowledge deficit' model persists, assuming expert knowledge is sufficient for public policy decisions.
• This model posits that public beliefs contradicting expert consensus are invalid justifications for policy.
• It suggests building public support for expert knowledge via education and public relations.

Purpose of the Study:

• To examine the 'knowledge deficit' model in contemporary liberal, technological societies.
• To challenge the model's assumptions using democratic theory.
• To illustrate the model's limitations with the genetically modified maize debate in Mexico.

Main Methods:

• Critical analysis of the 'knowledge deficit' model.
• Application of basic democratic theory.
• Case study: genetically modified maize debate in Mexico.

Main Results:

• The 'knowledge deficit' model is challenged as undemocratic.
• Public perceptions and beliefs are presented as potentially valid inputs for policy.
• The existence of 'knowledge deficits' among experts is highlighted.

Conclusions:

• The 'knowledge deficit' model is insufficient for democratic public policy.
• Democratic theory necessitates incorporating diverse public perspectives.
• Acknowledging expert knowledge deficits is crucial for balanced policy-making.
