When we have lots of information input, the area of our brains that makes intentional choices becomes less active and the part that drives us by habits and learned behavior takes the wheel. As a result, many of our decisions are made by habit. After a long day of overstimulation, we fall back on our habits—and for many of us that means social media. While we may read Twitter and Facebook in the morning, following links and engaging with individuals, at night we scroll mindlessly.
