Typically, this happens during newscasts. Whenever, we are watching a newscast, it wants to tell us that is all there to be seen. But in reality it can never be all of it.

And also unfortunately, most people just accept whatever newscasts tell them, without ever confirming by other sources that whatever is being told is indeed the truth.

This can shape minds in a certain direction in the long run. If not then the term media manipulation would not exist.

As finding the actual truth requires effort and hard work which we don’t want to and except TV newscasts to do it for us. And in result we develop a distorted view of reality.
