Dan Ariely, of Duke University, is one of the leading behavioral economists at work today. His books and talks reveal humbling insights about the limits of our rationality. In the video below, “Are we in control of our decisions?”, Ariely explores the theme of perceptual illusions. Similar to optical illusions, perceptual illusions cloud our ability see a situation clearly, ultimately leading us towards unwise outcomes. If we care about the quality of our long-term decisions,it seems prudent to take into consideration these decision-influencing factors.
