Answer: blinders
Explanation: Many people rely on personal experiences as a way of being informed and we mostly view this as the normal way things are supposed to be. This tends to blind us to other views as well as restrict individuals from observing the shortcomings of their perspective.
Social and cultural norms in a family setting are deeply ingrained and most times form the basis for the general outlook and expectations and other points of views are discarded or regarded as abnormal and strange. This is because we already have blinders on due to personal experience in our family situation.
