Egocentrism means giving value to own self-interest more and less or no regards to other's interest. One example of Egocentrism I encounter in my life is that people thinks that their own point of view is right and ignorant of other's point of view and more possibilities of solution of the problem other than own. Another word - Sociocentrism means giving value to own group's interest and assuming our group is the right one. One example of this I observed in life is the school/university you came from that such belief that we are better than them because we enrolled or came from this school. These things create a barrier in critical thinking because you exclude some possibilities and opportunities that may others possess. Some techniques that can overcome the barrier are open communication and socializing with other peer groups. These techniques can lead you to open yourself to the society and to other people and learn new knowledge with them.
