Social proof is the idea that humans subconsciously copy each other. It is ingrained deep in our DNA. We are so reliant on it because it makes it easier to make decisions all while looking fashionable and in line with society’s standards.
We’ll often take interest in similar things as our friends, family, and the people closest to us. For instance, we’ll watch the same sports as they do, listen to the same music, and even use the same smartphone brands.
