During World War II, propaganda movies were employed by nations to inspire patriotism and rally support for the war effort. Surprisingly, initial studies revealed that these films had little impact on soldiers’ enthusiasm for war. However, a peculiar phenomenon known as the sleeper effect emerged, where the persuasive influence of propaganda grew stronger over time. In this article, we delve into the sleeper effect, its psychological underpinnings, and its implications in the realms of propaganda and advertising.
The Discredited Source and the Lingering Message
The soldiers’ skepticism toward propaganda movies initially hindered their ability to influence opinions. The awareness of their propagandistic nature rendered their messages hollow and easily dismissed. Yet, nine weeks later, a significant shift occurred. Those who had viewed the movies displayed a higher level of support for the war compared to those who had not seen them. This unexpected reversal puzzled researchers, as it contradicted the notion that persuasive arguments tend to lose their impact over time.
The Sleeper Effect: Unveiling the Psychology Behind It
Psychologist Carl Hovland, the leader of the war department study, coined the term “sleeper effect” to describe this intriguing phenomenon. Unlike the decay of persuasive arguments over time, the sleeper effect suggests that if a message strikes a chord with an individual, its influence gradually intensifies. The fading memory of the source (e.g., the propaganda department) allows the message itself (e.g., the nobility of war) to persist and gain credibility. The discrediting force diminishes faster than the enduring message within our memories.
Extending the Sleeper Effect to Political Advertisements
In modern times, political elections often witness a barrage of negative advertisements aimed at tarnishing opponents’ records and reputations. Despite regulations requiring disclosure of the sponsor, studies consistently demonstrate that the sleeper effect operates even in these cases, particularly among undecided voters. The memory of the messenger fades, while the negative accusations persist, shaping opinions without the initial influence being consciously recognized.
The Power of Advertising and the Sleeper Effect
Advertising, an omnipresent force in our lives, continues to capture our attention despite our logical understanding of its intent. We may struggle to differentiate between information gleaned from well-researched articles and the subtle influence of advertisements. The sleeper effect reminds us that our memories often fail to retain the source of information, blurring the line between credible content and manipulative tactics employed by advertisers.
Thwarting the Sleeper Effect
While the sleeper effect poses a challenge, there are strategies to mitigate its impact on decision-making. First and foremost, be cautious of unsolicited advice, even if it appears well-intentioned. By maintaining a healthy skepticism, you can protect yourself to some extent from manipulation. Second, actively avoid sources contaminated with advertising, as they tend to blur the boundaries between reliable information and persuasive messaging. Fortunately, books continue to offer an ad-free haven for knowledge seekers. Lastly, train yourself to remember the source of every argument encountered. Investigate the motives behind different opinions and ask yourself, “Cui bono?”—who benefits? This diligent probing will undoubtedly slow down your decision-making process but will also refine your judgment and protect you from undue influence.
Conclusion
The sleeper effect reveals the intricate workings of our memory and how the discrediting force of a message fades faster than the message itself. Propaganda and advertising capitalize on this psychological phenomenon, influencing opinions long after the initial exposure. By understanding the sleeper effect and employing countermeasures, such as skepticism, source evaluation, and critical thinking, we can safeguard ourselves against manipulation and make more informed decisions in an increasingly persuasive world.
