Social media tricks your brain. It makes you feel like you're doing something important when you're really not.
When you post, comment, or argue online, your brain thinks you accomplished something. It doesn't matter if people agree with you or fight with you. Either way, you feel tired afterward, like you worked hard.
But nothing actually changed. The problems are still there.
This is exactly what powerful people want. If you're busy on your phone, you're not busy fixing real problems.
