Biases in Project Management and How to Overcome Them with the Two Systems of Thinking

Written by Bjarki Rúnar Sverrisson

Abstract

The Israeli-American 2002 Nobel Prize winner, Daniel Kahneman introduced the two systems of thinking in his book, „Thinking Fast and Slow“. He argues that every single decision a human being makes is made by one of two systems in the brain. He calls them System 1 and System 2. The systems have their own abilities, limitations, and functions. System 1 thinking is automatic, intuitive, and quick while System 2 thinking is intentional, analytical, and slow,

In project management, the decision-making process can be influenced by many things e.g. the cognitive biases of the people involved in the project. System 1 thinking can for example result in biases like the availability bias, where people prefer to overestimate the likelihood of occurrences that are easily recalled, and the confirmation bias, where people seek for information that confirms their already ideas. System 2 thinking can help people overcome these biases by analyzing data more thoroughly and making decisions based on a comprehensive understanding of the project's goals, risks, and opportunities.

Project managers should actively seek out varied perspectives and data sources, and participate in purposeful thought to reduce the biases brought on to them by System 1 thinking. They should also create decision-making processes that encourage critical thinking and exploration of alternative options. By being aware of the two systems of thought and the biases they imply, project managers can make better judgments and acheive projects more successfully. By adopting a deliberate thinking approach and implementing decision-making processes that encourage critical thinking, project managers can mitigate the biases associated with System 1 thinking and create a more effective project management process.

This article will focus on how the two systems of thinking and biases relate to decision-making in project management, and how project managers can overcome biases with System 2 thinking.

The Two Systems of Thinking

Daniel Kahneman, an Israeli-American psychologist, economist and 2002 Nobel Prize winner introduced the two systems of thinking in his book „Thinking Fast and Slow“. These two systems are referred to as System 1 and System 2. They are two different modes of thinking and Kahneman argues that every single decision a human being makes is made by either of them.

System 1 thinking is automatic, intuitive, and operates with little to no effort. It is often associated with patterns and emotions. It is responsible for unconscious decisions and can lead to errors and biases because it operates with shortcuts and heuristics rather than a careful analysis. However, it is essential for survival as it can process a lot of information quickly and without effort, making it useful for making the fast and effortless decisions in live. For example, if we see a snake, the System 1 thinking immediately makes us react. Operations of System 1 thinking is often beyond control as it operates without conscious awareness. It is therefore hard to detect when its thinking is causing biases. Therefore, it is very important to be aware of the biases associated with System 1 thinking. Example of activities that are operated by System 1 thinking are:

• Detect that an object is further away than another object.
• Detect hostility in a voice.
• Answer the result of 2 + 2.

System 2 thinking is intentional, analytical, and slow. Its operations are often associated with choice and concentration. Its thinking is more accurate, reliable, and less prone to biases than System 1 thinking but is not used all the time as it requires a lot more effort and time than System 1 thinking. According to Kahneman, most people tend to be lazy thinkers and seek to System 1 thinking whenever it is possible. Example of activities that are operated by System 2 thinking are:

• Compare the price of two products.
• Focus on the voice of some specific person in a crowded and loud room.
• Answer the result of 155 x 139.

The main differences between System 1 and System 2 can be seen on figure 1.

People identify themselves with System 2 as it decides what to think about and what to do. However we rely a lot more on System 1 in the daily live as it saves us time and effort . In fact, 98% of our thinking is done by System 1, leaving only 2% of our thinking to System 2 . When accuracy and reliability are crucial it is essential to use System 2 thinking to overcome the biases of System 1. It is therefore important for project managers to understand the two systems of thinking as it helps them being aware of biases that can be present if the reliance on System 1 is too much. By being aware of that, they can reduce biases which results in better decision making .

Biases in Project Management

Biases can impact decision-making in project managament significantly and it can lead to errors and mistakes. Biases can impact the project manager to overlook important information and make desicions that are not in the best interest of the project. Project managers have the opportunity to be better informed and make better decisions by being aware of biases . Number of biases identified by behavioral scientists is enourmous. The list of cognative biases on Wikipedia contains more than 200 items . Therefore it is not realistic to expect project managers to be aware of every bias there is but by being aware of when the most common biases in project management and System 1 may be influencing the decision-making, project managers can minimise their effects and make their decisions based logical information rather than predetermined beliefs and limited perspectives. This leads to better decision-making and more successful project outcomes . In this section the five most important behavioral biases in project management will be discussed .

Strategic misrepresentation

Strategic misrepresentation is also referred to as, political bias, strategic bias, power bias or the Machiavelli factor. This bias is the tendency to purposefully and methodically alter or misrepresent information for strategic reasons. The bias is common when the ultimate goal is considered more important that the methods that are used to achieve that goal. The bias can be traced to agency problems and political-organizational pressures, such as competition for limited resources or trying to gain a more prestigious position within the organization. Megaprojects are especially likely to be affected by strategic misrepresentation. That is because the bigger and more expensive the projects are, the more attention and involvement is from the top management which leads to more opportunities for political-organizational pressure.

A senior consultant at a Big-Four firm explained how strategic misrepresentation works in practice. When building his transport economics and policy group, he conducted feasibility studies as a subcontractor to engineers. To him it was clear that the engineers just wanted to justify the project. He asked one of the engineers why they consistently underestimated project costs. The engineer replied that if they gave the true expected cost, nothing would be build. This example shows how strategic misrepresentation works in practice. The bias is used to achieve a specific strategic objective which is in this case, securing funding and justifying the project .

Optimism bias

Optimism bias is a cognitive bias and is the tendency to be overly optimistic about the outcomes of planned action. This bias is non-deliberate i.e., people are affected by it unconsciously. It causes people to make decisions based on ideal vision of the future rather than a rational assessment of gains, losses, and probabilities. The bias leads to overestimation of positive events and underestimation of negative ones. For example, overestimation of benefits and underestimation of cost, leading to projects to not go as expected. While optimism can be good, it can be negative as well if people take risks that would have been avoided if they had they known the rational odds. Successful leaders have rare combination of hyper realism and can-do optimism. They plan for the worst-case scenario and remain optimistic .

Uniqueness bias

Uniqueness bias is the tendency that people see themselves as more remarkable and special than they are in fact e.g., healthier, smarter or, more attractive. In project management, it can be the tendency of planners and managers to see their projects as more remarkable than they are. This bias tends to prevent project managers from learning from other projects as they think the have little to learn from them as their project is unique. That has negative effects on the project success as project managers who see their projects as unique from other perform significantly worse than other project managers.

A project may be unique in its own specific geography and time. For example, A high-speed line has never been built in California before so a project of building a high-speed line there could be unique in that sense. But the project is only unique in California. Multiple high-speed lines have been built in other places, and the people handling the project of building high-speed lines in California could learn from those projects .
