Your observation is correct. The mind gets conditioned over the years in such a way that one remains attached to an idea. Reminds me of another observation. Most of us may have seen a circus at some point of time. You will observe that the elephants, supposedly very strong animals capable uprooting trees, are tied with ordinary ropes which are tied to grounded rods. If the elephant tries, it can easily uproot the rod and break free. But it doesn't. It's because of conditioning. When it was a baby, it was tied with strong chains. However it tried, escape wasn't possible. So the mind accepted it as a fact and now even a rope is difficult to break.
Thanks for your observation.
May Allah bless us with the strength to follow the true path.
