Research shows that, on average, humans correctly spot liars about half of the time

Polygraph tests, also known as lie detectors, are better at detecting lies than people, but they still aren't allowed in most courtrooms. That's in part because of mixed signals. For example, spikes in heart rate can be explained by the stress a person feels during interrogation rather than by their own deception. As a result, polygraph tests are prone to false accusations. Results are also unreliable when participants actually believe their lies, examiners have biases, and tricks are employed to help test-takers relax.

Novels sometimes use unreliable narrators

When we read a book, we’re effectively forced to take the narrator’s word for what’s unfolding. But what if that narrator has a biased take on those events?

Mark Zuckerberg apologized for not doing enough to stop the spread of misinformation on Facebook ahead of the 2016 election

In the final stretch leading up to the election, more than one-quarter of Americans visited a fake news site supporting either Trump or Clinton.
