This is not real. This is acting. And this is acting for the camera.
Anyone with a camera in their face will act.
But what is interesting is that we are expected to take this at face value and believe we are watching 'reality TV', or reality on TV.
Their problem is to suspend our disbelief.
And usually they suspend our disbelief when first they suspend their own disbelief and fully imagine the work, so then we can suspend our disbelief.
But when they lack the ability to fully imagine their work and suspend our disbelief, they act in bad faith and say, 'this is a true story', or 'this is reality TV'.
But what is worse is that the viewers also act in bad faith and believe they are watching reality on TV.
