The way people interact with Facebook is changing how they can be persuaded to think about or do a particular thing.
With tons of information presented at the same time, your brain is forced to decide quickly what’s relevant or interesting. Facebook and other social media services take advantage of this – pushing you to slip easily from thought to behavior. It emphasizes your impulses and decreases the opportunities for you to think more thoroughly about your perceptions, attitudes and decisions.
