Preconceived notions

Many would have justified it as a mere inference making, apparently it doesn’t appear so. Here I introduce to you the expectation-underestimating axis;

Set up expectation → observation → general idea plus inference making (read: preconceived notions) → judging → analyzing → (lowering down expectation=underestimating)

Is lowering down your expectation the same as underestimating? If that’s so I favor keeping it high.

high expectation=anticipating?
