What does overestimating mean?
Overestimating means making a guess that is too large or too favorable. People overestimate the amount of work a project will require, the demand for a product, the strength of an opponent, or another person's ability. The word is useful because it identifies a specific kind of error in judgment: a reality is judged to be greater than it really is. Overestimating is often discussed in terms of consequences, since an excessive estimate may lead to excessive spending, poor planning, or misplaced confidence. The related noun overestimation names the error or habit itself, while the base verb estimate is neutral and can be accurate or inaccurate.
