I don't see much evidence that society at large can take an interest in a subject and maintain a sophisticated position like "there isn't enough evidence here to form an opinion". The closest that seems to be achieved in practice is two interest groups completely at loggerheads, preventing any action due to their strident opposition of each other.
In game theory terms, is there a system where a consensus opinion and a focused group of crazies can coexist without compromising in the direction of the crazies? Because the power of a focused group of political extremists is so great that it distorts political action and has significant flow on effects to journalism as political forces vie for control of the public discourse. The type of discipline to deal with something like that is clearly beyond most citizens.
