We also selectively perceive data, hoping to find something that confirms our prior views. We ignore data that contradicts those prior views. We even reinterpret old evidence so it is more in sync with our perspective. Then, we only selectively remember those things that support our case. Last, we overuse Heuristics, which is defined as simple, efficient rules of thumb that have been proposed to explain how people make decisions, come to judgments and solve problems, typically when facing complex problems or incomplete information (call them mental short cuts). These short cuts often generate "systematic errors" or blind spots in our analytical reasoning. And that's only a partial list of analytical imperfections you have inherited. The good news: These defects can be overcome. We can develop an awareness of these specific defects, and we can learn to employ strategies that attempt to overcome these inherent analytical shortcomings.
