There isn’t a verified “Albert Einstein liar test” with two exact questions. The version that circulates online is usually a modern quote remix or a made- up psychology tip, not a documented Einstein saying.

What people usually mean

The two questions most often shared are:

  1. “What do you mean by that?”
  2. “How do you know that?”

Those questions can sometimes expose vague or inconsistent answers, but they are not an authenticated Einstein quote.

Why the rumor spreads

This idea gets repeated because it sounds clever and fits a common belief: liars often struggle when asked for specifics, evidence, or consistent details.

A lot of posts also mix it up with other misattributed Einstein quotes about truth and facts.

Clean answer

So the short answer is: there are no confirmed “2 questions” from Einstein.
If you want the common internet version, it’s usually “What do you mean by that?” and “How do you know that?”.
