Since the dawn of time, humans have tended to form clans... thereby excluding strangers, enemies and anyone who is different. We may not exactly encourage them, but such attitudes become entrenched at a very early age. Radio-Canada followed an experiment in a primary school that shows just how quickly our young people can assimilate discrimination and all its dangerous repercussions. A Quebec Grade 3 teacher conducted an experiment in which she contended that scientific studies prove shorter kids are generally more creative and intelligent, and taller ones are awkward and lazy. She divided her class up based on those assumptions. The next day, she turned the tables and had them switch roles. A handful of the nine-year-olds understood it was all a game, but for the rest it turned out to be a very powerful experience.
