The illusory truth effect on social media
In her 2017 TEDTalk, cyberspace analyst Laura Galante discussed how “our realities are increasingly based on the information that we’re consuming at the palm of our hand, and from the news feeds that we’re scanning, and the hashtags and stories that we see trending”. She suggests that this evolution in digital technology has turned our minds into “the most exploitable device on the planet”, particularly if you’re “accustomed to an unfiltered flow of information, now increasingly curated to your own tastes”.
There is truth to this. Working in digital marketing means being able to master these technological tools to influence consumer behaviour. But, with such a powerful tool that can not only affect customer choice but even things like elections, we are going to run into ethical concerns. One is the illusory truth effect on social media.
What is the illusory truth effect?
The illusory truth effect is also known as the validity effect, truth effect, or reiteration effect. It has come back into mainstream discussions following the concern surrounding fake news on the internet. The illusory truth effect could be one of the drivers allowing fake news to prosper online. So what is it?
The illusory truth effect refers to a phenomenon where people rate repeated statements as more truthful than non-repeated ones. The more someone ingests a piece of information, the more likely they are to believe it to be true. Whether this is based on a legitimate fact is irrelevant. This illusory truth phenomenon has been found time and time again by researchers and has been studied extensively in relation to marketing.
How does the illusory truth effect work?
Lisa Fazio, a psychologist at Vanderbilt University, explained that after hearing information a second and third time, your brain misinterprets the repetition as a signal for it being true. The fluency and frequency of the information you hear translates into a gut-feeling of truth.
Most of the time, this shortcut in our mental processes is beneficial. We don’t have to think long and hard every time someone tells us that plants need water to grow. We have heard it so many times that we understand it as true. But, when the illusory truth comes into effect, and the information we are being fed is false, it can cause massive problems.
The dangers of the illusory truth effect
In 2017, fake news convinced people that:
- Category six hurricanes exist – More than two million people shared this story about a category of hurricane that doesn’t exist.
- Sam Hyde, a comedian, was responsible for the London Bridge terror attacks – He was not.
- A Canadian imam closed his mosque doors to Christian victims of Storm Harvey – He did not.
You can see how the misinformation that goes viral on social media can be fuelled by ulterior motive and cause conflict. It has become such a problem that the UK government has announced an anti-fake news unit to combat the problem. Now consider the impact of the illusory truth effect on people who see this information several times a day. It doesn’t help that social media tailors your feed to similar articles, beliefs, and reports.
It’s not hard to see how misinformation and the illusory truth effect can influence people’s entire outlook on the truth which is already subjective. This means when in the wrong hands, social media is one of the most dangerous tools people can use to influence the human mind, just like Galante said.
Illusory truth in marketing
In marketing, taking advantage of the illusory truth effect by using misinformation is extremely unethical. If what you’re saying is factual, however, it can be a useful strategy. You can use it to spread brand awareness and increase interest in your products. But, you walk a fine line. Posting misinformation by accident can be just as harmful as doing so consciously.
This is why you need to hire a team of marketers. Your team should be aware of the ethical concerns that marketing can bring. They should check all your content for errors before it goes online. They should also ensure you’re using the power of digital marketing for everyone’s benefit. Don’t risk getting caught out sharing false information.
