As the dissemination of ideologies and ideas is crucial to think tanks they apply different strategies to reach as many audiences as possible. Therefore also the concept of education plays an important role. Educational and training programs are aimed at the influencers and future influencers of public opinion and shall lead to the acceptance of think tanks respective social, economical and political ideas. The label "educational activities" thus very often stands for nothing less than the dissemination of ideology.
Most think tanks regularly organize conferences, symposia and seminars to deliver their findings and ideas to a broader audience. RAND for example also runs a Ph.D. program at its Graduate School.

Expert system
Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to  artificial intelligence. The three main elements of expert systems are: (1) an interface which allows interaction between the system and the user, (2) a database (also called the knowledge base) which consists of axioms and rules, and (3) the inference engine, a computer program that executes the inference-making process. The disadvantage of rule-based expert systems is that they cannot handle unanticipated events, as every condition that may be encountered must be described by a rule. They also remain limited to narrow problem domains such as troubleshooting malfunctioning equipment or medical image interpretation, but still have the advantage of being much lower in costs compared with paying an expert or a team of specialists.
