Apparently, it's very easy to tell if a person is lying.
Just cut them off in the middle of their potential lie and say, "excuse me, can you please draw a capital letter Q on your forehead? Sorry, just a quick test."
Easy enough, right? (It will make more sense after you watch the video.)
This test is actually really cool and the logic behind it is even cooler. The direction in which you choose to write the letter is dependent on whether you're an introvert or an extrovert.
And extroverts are better liars…
Or are they?

And no, they're not, "hold up, are you lying to me?"
