Final answer:
Propaganda can spread lies and deception, promote superiority ideologies, and prevent clear thinking on critical issues, manipulating individuals’ thinking and behavior.
Step-by-step explanation:
Propaganda can have a number of negative effects on society and the way individuals think and behave. One such effect is the ability to spread lies and deception in the guise of progress, which can mislead the public about important issues or policies. Another adverse consequence is that propaganda can sway the minds of people, potentially leading them to believe in superiority ideologies, which has historically led to segregation and even genocides. Lastly, propaganda can prevent clear thinking on crucial issues, as it manipulates emotions rather than presenting factual information, making it challenging for individuals to make informed decisions.
