Cognitive Illusions investigates a wide range of fascinating psychological effects in the way we think, judge and remember in our everyday lives. At the beginning of each chapter, leading researchers in the field introduce the background to phenomena such as illusions of control, overconfidence and hindsight bias. This is followed by an explanation of the experimental context in which these illusions can be investigated and a theoretical discussion drawing conclusions about the wider implications of these fallacy and bias effects. Written with researchers and instructors in mind, this tightly edited, reader-friendly text provides both an overview of research in the area and many lively pedagogic features such as chapter summaries, further reading lists and suggestions for classroom demonstrations.

Who Am I? Why Am I Here? What Is Reality Really All About? Throughout mankind's history, our perceptive reality has led us to question who, what, and why we are here. What is this universe we perceive around us? These questions have been the driving force of our survival and have contributed to the evolution and proliferation of man's existence. While there have been many disciplines of thought which have attempted to answer these questions, the truth seems to elude us, thereby indicating a lack of satisfactory answers from all our religions, philosophies, mythologies, and sciences. Ironically, we do in fact have enough knowledge, experience, and information to discover, define, and comprehend the true nature of our existence, as well as our individual roles in it. To realize this requires the willingness to see things at their most basic level, and recognize that what we find there provides us the evidence to understand the foundation of all that exists. For thousands of years, theologians, philosophers, and scientists have monopolized the question of "what is reality?" Now it's a topic for the rest of us. Anyone sufficiently motivated to ask themselves questions such as "Who am I? Why am I here? What is this existence really all about?" already has the inherent ability and the direct evidence to find the answers. It is often said that truth can be stranger then fiction. No where is this more true then in the pages of this eBook.

A Consideration of: Reality, Human Nature, and Metaphysics is just that, a consideration of reality, human nature, and metaphysics. Dealing with reality, and more specifically how every person's perception of reality is different for numerous reasons and is the reason for an illusionary existence. It is written while looking at topics from various subjects such as human emotions, psychology, physics, and others. Looking at human nature on a basis of intelligence, specifically how the intelligence level in humans has become a burden upon all mankind on an individual basis and in small and large group dynamics, we look at how humans can be conflicted by discussing the conflict of the heart and mind in regards to love as well as the conflict of the main divisions of the mind from Freudian psychology. And finally mathematical concepts and constructs as well as theoretical sciences, especially physics from a metaphysical standpoint. By looking at the big bang theory, the universe expansion and contraction theory, wormhole theory, and even Einstein's theory of relativity, we come to see how erroneous these so-called accepted theories actually are by observing them logically, rationally, and with common sense. All the while trying to keep it simple.
