May be the word “complexity” does not stand out in our daily conversations. Its meaning, however, is inherent in many of our daily discussions. When we ask how did my child understand what I just said? or how did this person commit a murder when they lived a quiet decent life? When we see sudden transitions that make people and systems behave in a way that we have not seen before. When we see a single simple event cascades into a disastrous outcome. Complexity is pertaining in every event we encounter, every experience we live, and every surprise we face.
