While information may have the power to influence, it is clearly not true that all information
has such power. If I were earnestly to tell you that I had knowledge that pigs really
do fly, it is very unlikely that you would be persuaded. For you to be persuaded, other influence
processes would also have to be operating: for instance, the information might have
to be perceived to be consistent with normative expectations, or coercive or reward power
might have to operate.
