How do social media algorithms reinforce confirmation bias?

Social media algorithms can reinforce confirmation bias by creating "filter bubbles" and "echo chambers". These algorithms are designed to show users content that aligns with their existing beliefs and preferences. By prioritizing information that confirms what a person already thinks, these platforms limit exposure to diverse viewpoints. This selective exposure can lead individuals to become more entrenched in their beliefs, as they are less likely to encounter or consider information that challenges their perspectives. This process is largely unintentional but can result in a skewed understanding of issues and an overconfidence in one's own opinions.123
