In terms of critical thinking, there are millions of barriers that create a different meaning in a person’s life. The effect of these barriers can reflect on our emotional, psychological as well as personal state. Critical thinking whether as a student, professor or professional requires focus that leads to their successful stories. If, for instance the entire focus is upon how to rule out people from other culture from the company and disable them to get the similar level of treatment, this racism would lower the productivity of the people in workstation (Shelby, 2003). Your responsibility as a critical thinker is to be aware of the barriers, acknowledge the challenges they present, and overcome them to the best of your ability.
