"We all question things in our life, some more than others, but people rarely question their own religion. They may say they do, but the fact is that most people will follow the religion they were brought up in. If they really questioned it, we wouldn't see religions dominating certain populations around the world. Since religions shape the way people look at the world, it is extremely important for people to question their ideas and beliefs. Ideas in life affect people in three ways, negatively, neutrally, and positively. So let's look into how these three affects change the way things are perceived.
When an idea appears to affect us negatively, we have no problem questioning it. We want what is best for us, which is why we will question something that affects us negatively, because if we can prove there is another way, it benefits us. For example when politicians discuss raising taxes, if we can prove the state/country can still operate and accomplish everything they need to without raising taxes, it is better for us. So when something appears negative we question it and will usually attempt to prove it wrong.
When an idea appears neutral and doesn't really affect our lives, we rarely give it much thought. However, some do in attempts to make a product or a situation even better. Sometimes those changes are improvements, but if the changes turn out to have a negative effect, guess what? We question it. We will argue for changing it back the way it was, or attempt to improve on it again. But for the most part, most of us don't even question ideas that affect us neutrally because we don't think about it."
