The Third Instrument of Social Media's Power

Sally Kohn: Social media has expanded our reference networks like never before. She says people across the world now can influence our perceptions instantly and repeatedly. Our behavior is determined by the likes and dislikes of others we encounter on social media, she says. So if someone pushing back just makes the others a little bit more very about posting the next message, that's how it plays out in social media according to Kohn. The three meta mechanisms I feel we need to appreciate to understand social media's power arereference network expansion over to window expansion and disproportional rewards expansion.
