In a world where most of us are engrossed in our phones and social media more than what is actually going on in the real world, would you be able to notice if the person who started a conversation with you switched places mid sentence?

Stuart Edge and his friend tried out this theory using the ninja prank and the dating app, Hot or Not? to stir up conversation with strangers on the street. One of the males approached a group of girls promoting the other guy on the dating app. Mid conversation the switch would be made.

For the most part the group of strangers were completely oblivious to the switch being made until they made an attempt to make eye contact with one of the males.
