Multi-National corporations completing large-scale projects face potential high overruns and possible overestimations on initial budgets. Through these, sometimes unrealized setbacks, the corporations are not operating at maximum possible efficiency. This can happen through a number of factors such as a poor allocation of resources, lacking a sufficient standard of managerial skills, Optimism Bias and Strategic Misinterpretation.

A Danish geographer by name of Bent Flyvbjerg did extensive research into cost overrun and benefit shortfall of major projects, with additional studies into hypothetical solutions. Through his investigation, Flyvbjerg realised that the cost and benefit shortfall of major projects could be better understood by filtering the wide topic into two sub-topics, Optimism Bias and Strategic Misrepresentation. Through further analysis into the study area, a possible solution to this problem was first found through the use of the Reference Class Forecasting approach (RCF). RCF approach helps by providing a less skewed and opinionated view on a specific subject by using the 'Outside View' instead of the commonly applied 'Inside View'. The over-arching goal is to reduce cost overrun and benefit shortfall by engaging all aspects to increase forecasting accuracy[1].

Through reading this article, a clear and succinct explanation of the strategies and ideas mentioned above will be discussed. A brief analysis will be given on how it is used in business practice to increase efficiency and a detailed paragraph of the studies' limitations as a theory will also be covered.

Optimism Bias

Optimism bias by definition is a form of cognitive bias. This bias refers to the belief that there are reduced negative externalities about a specific situation[2]. Factors that contribute to Optimism bias is if an individual or corporation has a more informative view of the desired end state of the project, the cognitive mechanisms in use, the information the individual or company has to begin with and the overall mood of the project scope. All these factors significantly contribute to the bias, potentially skewing judgement on a project. Optimism bias can be both positive and negative, for example, an overoptimistic overall outcome of a project's benefits can lead to poor planning, budgeting and other factors in the early stages of the project portfolio. However, an increased Optimism Bias can be seen as quite a positive aspect of a business plan. An over-confidence in the desired outcome would increase expectations of an individual or company as it is falsely made to look that it is easier to achieve.

Although this sounds negative if not met, increased expectations help people in a corporation and the business its self, grow considerably as the company will continuously strive for potential new feats. Not only are potential higher target reached, but self-satisfaction is drastically increased no matter the outcome as noted by Psychologists Margaret Marshall and John Brown's theory of Optimism Bias presented by Associate Professor of Cognitive Neuroscience Tali Sharot in a TED talk [3]. The study found that when individuals succeed, they attribute their success to their personal traits. This increased satisfaction boosts continual drive for success, even with mishaps, the mentality of individuals has been changed to a higher level of output and thinking.

Strategic Misepresentation

In corporations, whether largely publicized or not strategic misrepresentation occurs and is almost inevitable. Through various factors may it be political, economic, social or all three cohesively implemented in unity, strategic misrepresentation is often used to seize a potential advantage on another company. This advantage can be exploited when one party or organization knows less information than the other or is relying on the other organizations' information for their own benefit.

When compiling a set of outcomes for a project or plan one party can purposely increase the number of deliverables or strategically underestimate the costs of the proposed scheme, pre-determining and quite likely also overestimating the potential clients' benefits. Politically speaking, in an organization, strategic misrepresentation can also be witnessed easily. Applying additional pressure and strain on individuals through manipulation, competing for scarce funds or jockeying for a position all qualify for the same over-arching category. Through this additional pressure, people have now been exposed to a form of bias and are swayed to a specific side for whatever reasoning[4].

It should be strongly noted that although Optimism bias and Strategic misrepresentation are both forms of biases, there is a sizeable difference between the two executions. Strategic misrepresentation, of course, a form of bias, it more a deception technique rather than an Optimism bias using deceit techniques on one's self. As mentioned prior, through a greater knowledge of a given topic increases the strategic misrepresentation with respect to pressure may it be political or organizational. A better demonstration of this theory can be visualised through the graph of explanatory power with respect to political and organizational pressure. Furthermore, the same graph clearly shows the Optimism bias has a polar opposite reaction to Strategic misrepresentation when comparing using these two categories.

Reference Class Forecasting

Reference Class Forecasting (RCF) is a method of looking to future events by taking relatable situations and their previous outcomes. This approach aims to give a much less biased view on a specific event. A study conducted by Daniel Kahneman and Amos Tversky in 1979 shows that when a project is in its beginning stages, judgement of the overall risks of any given events in the project, the total cost and the length of time it will take to complete, is quite often biased, sometimes even without the intention of bias. This phenomenon is called 'The Planning Fallacy'.This sensation was further investigated also by 2002 Nobel Prize winner Daniel Kahneman. The bases of this experience is that without any real means of desire, humans have a tendency to underestimate the time and resources that you will need to achieve your goals, as a corporation or as an individual[5]. To put this into perspective, the construction of the Sydney Opera House in Australia was originally estimated to cost a grand total of $7.0 million. At the productions' end, the accumulated spending exceeded $102.0 million. On completion of the Sydney Opera House, the project not only surpassed its budget by approximately $90.0 million but it was over ten years over the initially predicted arrival date.

The investigation from Kahneman and Tversky proved that it is entirely the norm to have an unplanned Optimism bias about future events. It has to be also noted that the same study found the there had been a deliberate bias towards costs of materials and labour as a company by previous project managers in an attempt to produce a lower final cost, lower than their opposing firms to ensure that the company would get the contract[6].


In 2003, Kahneman completed another investigation on the benefits of using the 'Outside View' in Reference Class Forecasting rather than using the 'Inside View'. Taking the 'Inside View' instead is combining favouritism to an idea by having a tendency to tilt more to it therefore obviously incorporating Optimism bias to the situation and having inaccurate readings and forecasts as a result. Furthermore, Kahneman stated that the 'Outside View' attempts to limit the amount of confidence and assurance to a specific situation by targeting the narrowmindedness and aims to eliminate it.

Professor Bent Flyvberg, in 2007, constructed another detailed overview of Reference Class Forecasting and incorporating both the 'Outside View' and the 'Inside View'. In doing this, Flyvberg created a basic yet efficient system to also further eliminate the overconfidence present in the 'Inside Views' reasoning. The Reference Class Forecasting process three-step approach states that;

  • It is critical to identify a Reference Class of a past similar project.
  • Establishing a probability distribution for a selected Reference Class for the parameters that are being forecasted is vital.
  • Comparing the specific project with the Reference Class distribution in order to establish the most likely outcome for the specific project is paramount for overall sufficiently accurate forecasting.

After extensive time and research observing both the Optimism bias and the Strategic misrepresentation, it can be noted that both methods undoubtedly rely heavily on Reference Class Forecasting for substantial adjustment and correction to minimalize bias.Through further readings on the topic of bias and possible alterations to theories and ideas already vastly researched, the Socratic method was revealed. Socrates was an ancient Greek philosopher and was said to be on of the finding fathers of Western philosophy. As many people in the ancient civilization of Greece said that he was the wisest humans alive, he insisted he did not understand anything. As a matter of fact, he questioned everything to better comprehend a specific situation, to eliminate gaps of uncertainty about a topic and acquire more background knowledge, improving his incite on the issue, however, not refuting the dilemma. This approach worked almost as an improvement mechanism for the matter of contention at hand, striving to get the most knowledge he could out of the situation. Socrates then further analyzed the given topic to make sense of the information presented and fathom what he knew and what he did not of the subject before making any substantial judgements on the issue[7].

As demonstrated, the philosopher took a 'less biased' approach to a specific contention. Through questioning every aspect of the theory he better understood the theories flaws and where it needed amending, but also unintentionally decreased the skewness and bias of the situation by a much-improved view by encompassing all background information.

Relating this theory to the corporate world, if more background knowledge and further understanding of the issue or project is adhered to, then a potential increase in accuracy in costs for constructions and time schedules could be achieved easier as the boost to the comprehension of the situation would significantly reduce the bias in a likely problem[8].
