Dogma is living with the results of other people's thinking. Be careful when allowing the opinions of others to smother your inner voice, but do remain open-minded to new ideas and information.
Open-mindedness - When we close our minds to new information or opinions it is often because they go against our beliefs or take us out of our comfort zone. Admitting to ourselves that new ideas and information that go against what we feel is right may make us feel that we were/are wrong. That is OK. Open-minded people are open to new ideas and new information even it they have to admit in the end they were wrong when believing something else.
As a project manager we rely on our beliefs and experiences and the beliefs and experiences of others to bring our projects to success. Be open-minded and encourage everyone on your team to express their ideas and opinions.
