Belief bias: If a conclusion supports your existing beliefs, you’ll rationalize anything that supports it.
People will rationalize anything, which is the most dangerous part of human nature.
Our brains are not designed for morality. They are designed to survive in small groups of hunter-gatherers living in the harsh wild and raising offspring while contending with nature and all her dangers.
This is why the world is the way it is. It’s why we have tribalism, racism, SJWs, cancel culture, terrorism, and more.
The salve to this is to become a self-aware person. Seek to ‘know thyself’ as Socrates said.
Here’s a simple way of thinking about it. Everyone has a pair of colored glasses over their eyes. Maybe they are red, blue, green, whatever. Each color is dependent on the bias the person holds. Some people have multi-lens glasses, meaning they have lens after lens after lens of bias distorting their perception.
The goal is to remove these lenses. One by one and to the best of your ability. It will take time. The more lens you remove, the clearer you can see, then less distortion, the closer you will get to objective truth.
Even then, you’ll miss somethings since you’re human, but you won’t make many of the same mistakes everyone else is making. This will give you the best chance of making decisions in your life for how best to live.
Or you can give in to your bias and curl up in your bubble of comfort. My problem with this is how destructive it is. It seems to chip away at your mental and physical health, so I can’t recommend it.
