We examined how scientific information influences policy beliefs among organizations in climate change policy networks in Germany and Japan. Different combinations of information types, policy beliefs, and organizational roles were found to play instrumental roles. Ideational influence can occur when (1) the sender is a credible information source, (2) the receiver can understand the “message,” and (3) the receiver depends on the sender's information. Organizational roles involved in this ideational influence are different in technical and political information exchange. The leverage of influence depends on the organizational ecology of different roles in each country.
