Psychologist and Educator, Howard Gardner once wrote,
"Hitler didn’t travel, Stalin didn’t travel, Saddam Hussein never traveled. They didn’t want to have their ideology challenged."
This statement makes great sense. Travel has the effect of widening a person’s world view, making them more broad-minded and tolerant of other peoples’ cultures and beliefs. Dictators have no use for differing points of view, so they probably minimize their exposure to the outside world, remaining insulated against intrusions. Since most people would not brag, "What’s good for Hitler, Stalin, and Hussein is good enough for me," thus, we should all try to travel in order to moderate our ideas and discard our biases.
