To an extent i wonder if posting close your thinking, you speak something into life, it takes up a stronger part of your subconscious and makes it harder to change your mind based on new information

It's different from person to person.

Some will get affected more then others.

I think everyone having his own opinion about something is right, but if you're based.. you stay with your opinion with the ability to look at it through someone elses eyes and reflect on it.

Only sticking to your opinion makes you stale..
