How do people get dum?

People can become "dumb" in various ways, often due to lack of education, exposure to diverse ideas, or critical thinking skills. Environmental factors, such as peer influence and societal norms, can also play a role in shaping one's beliefs and knowledge. Additionally, cognitive biases and misinformation can impede understanding and lead to less informed decisions. However, it's important to approach this topic with empathy, recognizing that everyone has different circumstances and opportunities for learning.
