We humans are surprisingly easily made to believe what we want to hear. We are even capable of adding details to fake news and this is the way we create fake memories associated with events that never happened.

Fake memories can be deceiving. Sometimes we can put fake memories into our memory without even knowing it. But they are there and we trust them so much that we wouldn't even have the smallest problem passing through a lie detector test. We don't even realize that what we remember didn't really happen. Fake memories played a scary role in a number of criminal cases but we can't avoid them in real life either.
An Irish-American team that was lead by Gillian Murphy from the University College Cork used the Irish referendum about abortions from 2018. Both the people who were pro-abortion and anti-abortion ran very intense media campaigns before the referendum. Luckily, the Irish law requires that both the pro-abortion and anti-abortion campaigns were equally represented in media. And this paid off. The Irish were quite upstanding citizens because almost two-thirds of all eligible voters came to vote. The experts expected the referendum to be a close call. But surprisingly, 66.4 % of the voters voted for the end of the ban on interruptions.
Before the referendum, the Irish scientists in cooperation with Elizabeth Loftus – the foremost expert on fake memories – and her team asked more than three thousand voters who were already decided on how they will vote if they could show them 6 news articles. Two of them were pure fake news. One accused pro-abortion advocates of illegal acts and the other did the same about anti-abortion advocates. Then they asked the people if they ever read any of the 6 articles. And if they knew any of them, if they could add any details that weren't mentioned in the articles themselves.
The volunteers were told that some of the news may be fake and they were also asked to attempt to figure out which they think are true and which are fake.
The results are quite interesting. More than half of the people were capable of adding details to at least one of the fake news articles. Many added a lot of detail to a news article they could not ever read or even heard about because it was completely fabricated. This is a prime example of fake memories. And as you might guess, pro-abortion advocates were more likely to have fake memories of articles smearing anti-abortion advocates and vice-versa. And nothing changed when they knew some of the news was fake. On top of this, the volunteers underwent an IQ test. There is no evidence that people with a lower IQ are more likely (or less likely) to have fake memories.
Fake memories are a really interesting phenomenon. But one that shouldn't be taken lightly. Every single one of us likely has some. Thus, in the future, if you are going to talk about something, make sure it is actually what happened. Especially if it is something you are prone to agree with on principle or because it suits your worldview.
