How does ignorance correlate with the power of propaganda?

The definition of ignorance is a lack of knowledge or information. The definition of propaganda is official government communications that are designed to influence people's opinions. The correlation between ignorance and the power of propaganda is as follows: The less a person knows or is informed about, the greater chance there is that propaganda will influence them. Governments often do not want their citizens to know what they are doing so they proclaim a blackout on news and information. This increases a government's ability to use the power of propaganda to persuade the people to believe what it is doing is correct.
