Why do we forget most of what we take in?

We forget most of what we take in due to the brain's limited capacity to retain information and the natural decay of memory over time. Factors such as lack of attention, insufficient encoding, and interference from new information contribute to this phenomenon. Additionally, our brains prioritize information that is deemed more relevant or emotionally significant, leading to the discarding of less important details. This process helps us manage cognitive load and focus on what truly matters.
