This! So much this! Just about any communal animal likes to be around others that look, communicate, and behave like themselves. It&#x27;s a natural effect that promotes safety and efficiency.<p>To acknowledge that we have this blind spot and ensure that we shine extra light into it is the only way to mitigate its effect. Cultural, like genetic, diversity is a good thing. We achieve by standing on the shoulders of giants. Giants come in all shapes and colors.<p>If we continue to surround ourselves with like-minded individuals, we will never learn what we don&#x27;t know. It is by gradually incorporating foreign ideas and concepts that initially challenge our own that we grow as a society. Two hundred fifty years ago, we thought it was acceptable to <i>own</i> another human. Two thousand five hundred years ago, we thought the earth was flat. Twenty years ago, we thought the Spice Girls were the pinnacle of musical achievement.<p>It is particularly difficult to accept these new people and ideas because it forces us to reconsider our beliefs and admit we were wrong. But when we know better, we do better. Be self critical and form new opinions when exposed to the new and different.
