Study Finds One Simple Trick to Detect Lies with 80% Accuracy
Detecting lies accurately has long been a goal of psychologists, law enforcement and other professionals. Recently, a study conducted at Tel Aviv University revealed a simple trick that can detect lies with 80% accuracy.
The researchers conducted several experiments to examine the effectiveness of this technique, and their findings suggest that it could be an essential tool for identifying deception in real-world settings.
Lying is a typical behavior in human interaction. It can have severe consequences in certain situations. However, identifying deception can be challenging, as liars can be highly skilled at concealing dishonesty.
The Challenge with Lie Detection
Studies indicate that trained professionals have only a slightly better chance than random guessing when trying to distinguish truth from falsehood.

The challenge lies in the complex task of assimilating conflicting data points in real-time and arriving at a definitive conclusion regarding the veracity of a statement. This difficulty makes it challenging to make binary decisions about whether someone is telling the truth.
In addition, individuals tend to rely on preconceived notions of how innocent or guilty individuals should appear, despite stereotypes having limited predictability for determining whether someone is telling the truth or lying.

You Can Now Detect Lies with One Simple Trick
The trick involves paying attention to the tone of the speaker’s voice. According to the researchers, liars use a higher-pitched voice when they lie, while truth-tellers maintain a more consistent pitch throughout their speech.
The researchers could accurately detect lies in 80% of the studied cases by analyzing the speaker’s pitch.
To test their hypothesis, the researchers conducted two experiments. In the first experiment, they recorded participants as they answered questions about a stolen wallet. Some of the participants had stolen the wallet, while others had not.
The researchers then asked participants to listen to the recordings and determine who was lying. The results of the first experiment were promising.
The participants who listened to the recordings could accurately identify the liars 75% of the time, which is significantly better than chance.
In the second experiment, the researchers examined the effectiveness of the pitch trick in a more realistic setting. They asked participants to participate in a mock job interview, during which they received instructions to lie about their qualifications.
Again, the researchers recorded the interviews. They asked a separate group of participants to listen to the recordings and determine who was lying.
The results of the second experiment were even more impressive. The participants who listened to the recordings could accurately identify the liars 80% of the time, significantly improving over the first experiment.
These findings suggest that paying attention to the tone of the speaker’s voice could be a valuable tool for identifying deception in real-world situations.

However, this technique could be better, and there are certain situations in which liars may be able to maintain a consistent pitch throughout their speech.
How Reliable is this Study?
Moreover, the research has some limitations. The participants in the study were undergraduate students. This implies that the results may not generalize to other populations, such as professionals or individuals with a history of lying.
Nonetheless, the study’s findings offer good insights into the psychology of lying. It may help individuals become more adept at detecting deception.
While it’s not always easy to identify when someone is lying, this simple trick could provide a useful starting point for improving their lie-detection skills.
