Since we only have the capacity to focus on a fraction of what we encounter, our brains are constantly filtering what gets our attention. In this filtering process, our brains are easily distracted because we are wired to pay attention to any new stimulus, especially if we perceive it to be a threat to our survival. This filtering causes us to have what psychologists call a negativity bias.
