A Three Part Series
In the study of economics, understanding individual incentives is critical to understanding motivation, decision making, and economic outcomes. At the decision point, understanding one's "locus of control" and related psychology is the key to unlocking an individual's rational mindset. Decision support solutions can be a big help to bring together people with different loci of control, different professional judgements and for the purpose of driving optimal and efficient decisions.
This is Part 1 of a three part series.

Decision making economics and psychology background
There is much to unpack here, so we will start with rationality, then move to locus of control. We will help to bring the ideas together with a train thought experiment. We will conclude by discussing group decision making leadership approaches, methodologies, and solutions.
There was a time, when economists thought of rationality as a collective fixed point. Economists would determine a single "economic rational" decision for a particular question. That single economic rationality was then assumed to be the long term equilibrium for all the economic participants. Any deviation from that economic rationality was considered a short term aberration, but inevitably on its way to the long term economically rational equilibrium.
Paul Samuelson, John Muth, Robert Lucas and others used fixed economic rationality as an underlying assumption to build mathematical-based models and theories. (1) Ultimately, many of those theories have lost some of their explanatory power. (Or, perhaps, those theories did not have much explanatory power in the first place.) Behavioral economists such as Daniel Kahneman, Amos Tversky, Richard Thaler and others consider economic rationality as relative. That is, rationality is relative to the individual, behaviorally-based, and varies across a multimodal distribution. (2) Across a large number of people, fixed economic rationality is only a boundary condition. Thus, aggregating individual rational preferences is very tricky. As such, "rationality" is user defined and very sensitive to local conditions at the time the decision is made. If you have ever asked someone "Why did you do that?" a common answer is often,
"Well, it seemed like a good idea at the time."
This is exemplar rationality in the real world.
Since rationality is relative, psychological concepts like "Locus of Control" is critical to understanding one's rational mindset at the time an economic decision is made. First, lets start with a definition (3):
Locus of control is the degree to which people believe that they, as opposed to external forces (beyond their influence), have control over the outcome of events in their lives. A person's "locus" is conceptualized as
1) Internal - a belief that one can control one's own life or
2) External - a belief that life is controlled by outside factors which the person cannot influence, or that chance or fate controls their lives
People may perceive varying loci of control along a continuum. Individuals and cultures may have different propensities for locus of control. For example, the American individualistic culture will skew more toward the internal locus of control. But situations certainly impact one's locus of control mindset at the time a decision is made. Different levels of uncertainty between situations may cause an individual to have situationally dependent loci of control.
Also, individuals tend to assign locus of control based on decision outcomes. In identical situations, it is natural to associate:
Positive outcomes with an Internal Locus of Control. (i.e., “My hard work caused this positive outcome”), or
Negative outcomes with an External Locus of Control. (i.e., “The actions of others caused this negative outcome”)
Naturally, if the situation is identical, you cannot have it both ways. The actual situation outcome must exist at a single point on the causality spectrum. Thus, there is a gap between actual control and one's psychology-based locus of control. The gap or variability from actual is also known as noise. (4) Noise may be driven by:
People, related to uncertainty or education level;
The same person in different situations; or
The same person in the same situation but in different conditions.
As part of my American cultural programming, I tend to initiate myself on the "I am in control of my fate" end of the spectrum. Only after deeply learning about a system's dynamics, does my reality shift to the "I have less control than I thought" end of the spectrum. I must admit, the optimism and determination associated with "I am in control of my own fate" is very helpful. It is almost like I start by fooling myself, but I believe that optimism and determination does sustain me to do better work. If I was initially more realistic, maybe I would not have done as well, even though I had less control than I thought. It is quite a paradox!
Also, having an understanding of one's impact on an organizational system at the system's level does help one understand the system’s dynamics, their place in the system, and helps one understand how to get the most out of the system, even if one has less control than they originally thought over the system.

It also shows how psychological anchoring can impact this reaction. Daniel Kahneman earned a Nobel Prize as a result of this theory and work related to the integration of psychology and economics.
