In our previous video, we have explored how Romans take advantage of histories in order to create a sense of belonging. Well, the exploration of the relevance of histories provide us an additional view to take advantage of cognitive diversity. Let me start with a well-known effect. It's called the PowerPoint effect. It's basically related with how powerful PowerPoint is in order to create, in order to define the way in which we make decisions. In fact, there are some concern within the managerial world in order to see how PowerPoint has created a very specific bias in our decision-making processes. Well, why PowerPoint is so important? Well, because has become basically ambiguous tool in order to provide information regarding managerial decisions. The nature of PowerPoint is clearly related with a different knowledge that we explored in our past module regarding perception. Remember that all of us has to deal with two complimentary information, hard data, sensing, a self-information more based on relationship, that is basically the core on intuition. Well, PowerPoint is extremely useful dealing with hard data, dealing with sensing information in order to force our decisions in a very specific way. But unfortunately, PowerPoint is not our most natural way to share information. The most natural way for us as human beings to share information is about to tell a story around a fire camp. That produce something very interesting. We have figured out that the PowerPoint base decision-making process has a bias that could lead us in the wrong way. But the usage of something closer to the narrative approach provide us new cues in order to deal with information, both hard data information, sensing and self information intuition. Why narratives? Why storytelling is so important, so useful for us in order to make the right decision? Well, because in a very simple way is able to provide us a lot of information, for example, if we think about a fairy tale. Fairy tale is able to provide us the context, the setting. We are able to understand who are the characters, and where, and when things are going to happen. This is truly important in order to create contexts awareness. Second, every story has key characters that provide us a clear model of behavior, in fact, are extremely useful in order to create within a group unexpected behavior at consensus about the most desirable behavior to be created. Finally, we have the plot, and each plot, remember, we have an introduction of the characters and opening the scene in which the tension increase till we reach basically at the end of the story. Basically, every end of the story provide us a clear relationship between the characters, their behaviors, and the setting and the expected outcome. On other side, as human beings, we are extremely well-trained by nature in order to detect, in order to identify if a narrative, a story works or not. This is basically a matter of plausibility, is a matter of credibility. That means that in a natural way we are able to detect inconsistencies within a story. We can see if a character is behaving in a way that it's not expected. We can identify if some component basically in the surrounding reality in the environment of the plot is not fitting well with the behavior, or with the outcome. In terms of decision-making that provide us a wonderful way to integrate very different information, formal and informal information, and to develop an intuitive approach to the decision-making, that quite often is richer, safer, and most useful than traditional hard data decision-making process.
