Confirmation bias is the tendency to seek, interpret, and remember information in a way that confirms our existing beliefs, while ignoring evidence that challenges them.
For example, someone who believes a particular diet works may only notice success stories and dismiss scientific studies that contradict it. Social media often reinforces this bias by presenting us with content that aligns with our views.
While confirmation bias can protect our worldview and reduce mental effort, it can also trap us in echo chambers and block growth. Being aware of it helps us stay open-minded and consider alternative perspectives.
