“To catch a liar red-handed, all you have to do is ask them two questions…”
This type of statement circulates widely on social media, but there is no proven historical evidence that Einstein ever uttered these exact words. His name is often invoked to legitimize modern psychological advice.
However, beyond this attribution, the idea is based on genuine principles of behavioral psychology.
To unmask a liar, ask them these two questions.

Detecting a lie doesn’t depend on magical intuition, but on observing consistency.
Studies on deception show that lying requires more cognitive effort than telling the truth. A liar must:
Invent details
Maintain temporal consistency
Remember what they’ve already said
Control their body language
“Tell me exactly how it happened, step by step.” When someone tells the truth, they generally recall events with a certain fluency, even if they forget minor details.
A liar tends to:
Be too lazy
Or excessively detailed in irrelevant parts
Avoid a clear chronology
Asking for a step-by-step reconstruction increases cognitive strain.
Inconsistencies usually appear when the narrative needs to be structured.
“What happened right before and right after?” This is the key question.
Most lies are about the main event. What happens before and after is generally less planned.
By extending the time frame:
Contradictions are detected.
Changes in the story.
Unusual hesitations.
Genuine recollections generally include context. Lies focus on the essentials.
What NOT to do:
Don’t make direct accusations without evidence.
Don’t constantly interrupt.
Don’t look for “universal signs” like avoiding eye contact (this doesn’t always indicate a lie).
Effective detection relies on narrative inconsistencies, not isolated gestures.
No technique is foolproof.
Some nervous people can give the impression of lying.
Some trained people can lie with great consistency.
The best tool is not aggressive confrontation, but patient observation.

Final Reflection:
This viral expression simplifies a complex process.
It’s not about capturing, but about understanding.
The truth tends to remain stable over time. Lies require constant maintenance.
And when a story changes under the pressure of simple questions… it’s usually not by chance.
