==Psychological issues==

There are many psychological factors potentially explaining the strong tendency towards over-optimistic effort estimates that need to be dealt with to increase accuracy of effort estimates. These factors are essential to consider even when using formal estimation models, because much of the input to these models is judgment-based. Factors that have been demonstrated to be important are: [[Wishfulwishful thinking]], [[Anchoring (cognitive bias)|anchoring]], [[planning fallacy]] and [[cognitive dissonance]]. A discussion on these and other factors can be found in work by Jørgensen and Grimstad.<ref>{{cite web
