Assessing the role and strengths and weaknesses of sensory perception and intuition in Dan Ariely's TED talk, “Are We control over our decisions? Sensory perception is a way of knowing by which a person can acquire knowledge using their five senses: taste, touch, sight, hearing and smell. Sensory perception is important in our understanding of the world and is a source of pleasure in our lives. But can we trust our senses to tell us the truth? This question may seem strange to many because, from experience and history, it is known that humans rely greatly on sensory perception to survive. However, like all ways of knowing, sensory perception has its weakness; our senses can easily be deceived. In his TED talk, “Are we in control of our decisions? » Behavioral economist Dan Ariely uses examples and optical illusions to demonstrate the roles, strengths, and limitations of sensory perception as a means of knowing. The simple optical illusions Ariely uses show us how easily our senses can distort our judgments. The first illusion was an animation of Shepard's tables; an example of size constancy expansion first published by Roger Shepard under the title "Turning the Tables". We know that both tables are the same length, but why does one table seem longer than the other? In this case, it's because angles suggest depth and perspective and the brain mistakenly believes that one table is longer and the other is shorter. Interestingly, even though we know that the tables are actually the same length, we still perceive them to be different lengths; Even though we know the truth, we fail to bring our minds to see reality as it really is. In the second example, Ariely shows the middle of the paper rather than the actual decision maker. This shows how our irrational decisions can be influenced by just small changes. This begs the question; can we really trust our often irrational intuition to make the right decisions? Or is it necessary that we resort to rational, more time-consuming decision-making whenever we are faced with a difficult or complicated decision? I believe that intuition can be used to make correct decisions when the situation is known, understood or believed by instinct. However, when the situation is more complex, has broad implications and is not so common, as in the case of organ donation, intuition should not be used because it would lead to conclusions and results that might not actually be desired by the decision. -manufacturer. On the contrary, when faced with difficult situations, intuition and reason must be used together.
