The most dangerous phrase in the language is, “we’ve always done it this way.”
“Come on, let’s mix it up!” The heart surgeon says.
“B-but we’ve always done it this way!” The other replies, “this is how you replace a heart valve.”
“That’s the most dangerous phrase in the human language!” The first surgeon replies haughtily as he inputs a fruit loop into the patient’s heart. “This will be his valve. He will be a fruit loop in a world of Cheerios.”

This is serious business, because this is a large part of how sexism, racism, homophobia, rape culture, ethnocentrism, etc. continue to happen.
The reason we do heart surgeries the way we do is not “because that’s what we’ve always done.” It’s because that’s how year of scientific research says will give the best results. One of the best uses of the scientific method is to test common practice, and either eliminate it or give it legitimacy. Don’t do things because “that’s what we’ve always done,” do them because that is what evidence and research say we should do.
Saying “we’ve always done it this way” justifying maintaining a harmful societal norm is dangerous. We can do better.
