For example, it is not uncommon to find powerful scientific elites dominating national STI agendas, particularly in countries with a less mature innovation system. This can become a serious obstacle to developing policies that could set the innovation system on a more dynamic path. The greater involvement of business actors and organised interests in public policy formulation and implementation has to some extent resulted in blurring of the public-private distinction. Finally, some STI policy arenas see a greater role for direct citizen participation in agenda setting, although this remains relatively rare.
