When we are growing up, we learn from everybody around us. We learn how to interact with others; how to share, how to eat, how to think. We believe most of what we are told growing up, and if we don’t believe it, we might be shouted at, or told we are wrong; and we soon learn not to speak up, to ‘swallow’ others’ opinions we don’t necessarily agree with at the time.
It could be argued that, if we grow up healthily, we are encouraged to question the world.
Ideally, we would be taught to form our own opinions and respect other people’s opinions, but not necessarily subscribe to them. However, if we aren’t encouraged to question things, if we are told lies by adults we look up to and trust, we’ll probably learn to follow what we are told. We will learn to think as we have been told and act on this information without questioning its validity.
