Are humans really rational?

 Human rationality and irrationality is a complex and profound subject. Although we wish we were rational beings, the fact is that our behavior and decision-making are often influenced by a variety of irrational factors. Emotions, cognitive biases, social and cultural contexts, and limited rationality all play important roles in our thinking and behavior. First, emotions are one of the key drivers of our thinking and behavior. The presence of emotions causes us to have emotional reactions such as love, loathing, or fear towards certain things, which in turn affects our decision-making process. For example, fear may lead us to make conservative decisions, while anger may cause us to act impulsively. 

Second, cognitive bias is also a common feature of the human mind. We tend to selectively accept and process information and ignore information that contradicts our existing perceptions. This bias may lead us to make wrong assessments or decisions about certain things, thus affecting our behavior. Further, socio-cultural factors also have a significant impact on our decision-making. We are often shaped by social norms, values, and cultural traditions, and are to some extent subservient to the influence of these factors rather than based on rational thought alone. 

Finally, human rationality is limited. When faced with complex problems or incomplete information, we may employ heuristics and simplifying strategies to process information rather than engage in comprehensive rational analysis. Although human rationality is affected by a variety of irrational factors, rational thinking still plays an important role in many situations, especially when we need to make decisions and solve problems. Thus, our decisions and behaviors are often the result of a combination of rational and irrational factors, reflecting our nature as complex creatures.
