I think the older one is, the more likely they are to speak their mind, right, wrong or indifferent.
And then there are those who measure such things.
The younger one is the more likely they are to modify what they think or feel so as to not hurt one's feelings or cast doubt or be not in the popular majority.
Political correctness (
