It's great to keep an open mind.... just be careful to not lean too far over (philosophically) and let common sense pour out one ear as someone else is pouring bullshit in the other... otherwise you'll be "full of it..."

I often like to flip the SHARP products advertising line: "From SHARP minds come SHARP Products" to "From simple minds come simple answers". It's mental laziness that makes a person automatically accept an easy answer to a complicated issue.
Sometimes - the answer is a simple truth.
Sometimes - we cloud the issue with personal prejudices - often unconsciously.
Have the moral courage to change your opinion if new evidence is convincing.

Take the time to think.
