The Orange Value System of Spiral Dynamics

What is the theory of Spiral Dynamics?


Spiral Dynamics is a model of the evolution of individuals and societies' value systems (memes). Each has its code and color with a unique set of value orientations and priorities that form its beliefs and values. People and societies dynamically move through these levels depending on the changing conditions of life, experience, and challenges that stand in their way.


Who created Spiral Dynamics?


The beginning was laid by the research of Dr. Clare W. Graves

The term Spiral Dynamics was used by Don Beck and Christopher Cowan in the book «Spiral Dynamics: Mastering Values, Leadership, and Change.»

The orange value system focuses on reason, science, and technology. It is characterized by a focus on achieving goals and objectives through using rational, logical thinking and applying scientific methods. According to the Spiral Dynamics model, this value system is often associated with modern industrial societies and is considered the fifth level of human development. People in orange vMeme tend to be ambitious and goal-oriented; they value progress, efficiency, and results. They tend to be rational, logical, and analytical in their thinking and problem-solving. They are driven by a desire for knowledge and understanding and use scientific and technological methods to achieve their goals. They tend to be individualistic and competitive, valuing independence and self-reliance. They have little regard for tradition and are skeptical of spiritual or religious beliefs.

The Orange Value System through the lenses of SDTEST® 


SDTEST® has 36 different VUCA polls that calculate the 13,034 correlation values between stages of development according to the theory of Spiral Dynamics and answer options of these 33 polls.

We invite curiosity about the systemic mechanisms behind this correlation. There may be hidden variables that provide alternative explanations.


In our analysis of the poll "What makes a boss a great leader?" we found an intriguing negative correlation that warrants closer examination: 


-0.1513 between the Empathy and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0475. This negative correlation -0.1513 meets the reliability criteria but does not necessarily imply causation.



Given the Orange vMeme's focus on data, logic, and results over social-emotional intelligence, this -0.1513 negative correlation makes sense. Orange psychology risks losing touch with human needs and relational nuance in chasing progress through reason and strategy.


However, the picture may be more complex; purely rational decision-making has limits, and even competitive Orange leaders must consider how to motivate teams. It would be worth exploring whether certain expressions of Orange thinking allow room for empathy's inspirational power.


We must avoid conflating correlation with causation and assuming no form of Orange success integrates empathy. This provocative finding opens the insightful dialogue about social-emotional intelligence, even in the most metric-driven leaders. We welcome additional respectful perspectives!



In our analysis of the poll "Are you ready to receive less pay to work remotely?" we found an intriguing positive correlation that warrants closer examination:  


0.1245 between I am not ready to receive less pay to work remotely and Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0687. This positive correlation of 0.1245 meets the reliability criteria but does not necessarily imply causation.  



This positive correlation of 0.1245 resonates with key aspects of achievement-oriented Orange psychology. Viewing workplace dynamics through a lens of rational goals and incentives, Orange's thinking balks at the notion of reduced pay for equivalent productivity simply due to location.


Valuing measurable outputs over processes, those identifying with Orange success paradigms expect proper compensation for hitting targets and furthering strategic objectives. They pride pay rates on meritocratic contributions, not appearances.



In our analysis of the poll "Where would be your next most exciting opportunity?" we found an intriguing positive correlation that warrants closer examination:  


0.1282 between the International Market leader and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0643. This positive correlation of 0.1282 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.1282 makes sense given the Orange drive toward progress and achievement by competing rationally in a meritocratic system. Those identifying with Orange aim to strategically excel according to analytics-based best practices, seizing widening opportunities and platforms to demonstrate functional mastery.


Thus, the prospect of contributing efficiencies to renowned international corporations resonates strongly; scaling one's concrete impacts through well-resourced industry giants aligns with the Orange quest for visible, measurable influence through competence. The opportunity to shape global systems also appeals to knowledge-driven Orange mentalities.



In our analysis of the poll "Meritocracy" (Are employees encouraged to take ownership of their work, make decisions, and take the initiative rather than relying on top-down directives?), we found an intriguing positive correlation that warrants closer examination:  


0.24 between the YES, take ownership of their work, make decisions, and take the initiative and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.1154. This positive correlation of 0.24 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.24 makes sense given the Orange drive toward innovation and efficiency through decentralized competence and meritocratic autonomy. Those identifying with Orange aim to structure organizations and incentives in ways that align authority with the ability demonstrated through results.


Thus, Orange thinkers advocate pushing decision rights outward to those closest to operational reality, equipping them with data-driven accountability to excel. Such entrepreneurial initiatives unlock closer responsiveness, meeting customer needs and seizing market opportunities. It also boosts engagement as talent feels trusted through empowerment tied directly to their performance.



In our analysis of the poll "Gender difference in building self-confidence (IFD Allensbach)," we found an intriguing negative correlation that warrants closer examination:  


-0.1946 between the Recognition by women and the Orange stage.

The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.1329. This positive correlation of -0.1946 meets the reliability criteria but does not necessarily imply causation.


This negative correlation of -0.1946 makes sense when we consider the Orange value system's emphasis on achievement, autonomy, and rational thinking. From an Orange view, building confidence is largely an individual undertaking based on one's competitive talents and merits. Relying on external validation from others and exceedingly vague recognition from women seems antithetical.

Orange sees identity coming from measurable accomplishments, not arbitrary affirmations. Confidence arises from mastering impersonal systems through expertise and strategy. Leveraging scientific knowledge and technical skills to attain clearly defined goals is more critical than social feedback.

Additionally, in achievement-oriented Orange, gender plays little role in determining worthiness. Credentialed capacity based on expertise matters more than relationships or group perceptions. Seeking approval in gendered terms distracts from impartial indicators of ability.

Confidence stems from tracked progress on objective tasks, not subjective opinions. Social reinforcement is supplemental at best, and gender is deemed irrelevant. This perspective explains Orange's divergence from the consensus on the importance of female recognition. The correlation reflects Orange's specialized mindset.


In our analysis of the poll "Ageism’s causes," we found an intriguing positive correlation that warrants closer examination:  


0.1597 between the Yes, ageism is the result only of interpersonal interactions and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0934. This positive correlation of 0.1597 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.1597 aligns with Orange's rational worldview, prioritizing objectives over subjective group biases. From an individualistic Orange perspective, discrimination stems from personal behaviors rather than broad social constructs.


Orange trusts quantifiable skills, credentials, and expertise over vague demographic traits like age. Judging capacity based on age brackets seems irrational compared to concrete performance data. Any prejudice must arise from individual interactions, not systemic patterning.


Additionally, Orange strives to optimize processes based on meritocratic metrics blind to inborn attributes. If organizational outcomes exhibit ageism, it gets reframed as inefficient filtering rather than embedded cultural norms. The solution becomes removing subjective human decision gates rather than transforming beliefs.


In sum, Orange sees both prejudice and progress in mechanistic terms. Ageism reflects suboptimal personal exchanges, not societal conventions. Fixes come through reengineering neutral systems instead of moral persuasion in groups. The correlation reflects Orange’s extreme objectivity when evaluating social challenges.



In our analysis of the poll "What will you do this week to look after your mental health?" we found an intriguing negative correlation that warrants closer examination:  


-0.0771 between the Practice mindfulness and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0736. This negative correlation of -0.0771 meets the reliability criteria but does not necessarily imply causation. 




This negative correlation of -0.0771 makes sense, given Orange's rational, objective, and quantifiable approach to accomplishment. Practicing mindfulness requires sustained, patient attention inward - a faculty less developed in achievement-focused orange.


From an Orange perspective, valuable time examining thoughts and emotions takes away from designing, optimizing, and building external systems. There is skepticism around the business case for mindfulness without hard evidence of impact. 


Additionally, mindfulness threatens to disrupt Orange's sense of intellectual control and confidence in empirical data as the supreme lens of reality. Emotions seem dangerously irrational, even weakening, compared to reason.


However, as more research demonstrates mindfulness' benefits for concentration, lowered stress, and boosted well-being, the Orange perspective may gradually integrate this mental skill as another valuable tool for enhanced outcomes. It may become another technique for greater efficiency.


For now, this negative correlation exposes Orange's blind spots around inner terrain, preferring to chart progress through statistics, systems, and engineered environments to manage wellbeing. The seeming illogic of mindfulness undermines Orange's reliance on logic.



In our analysis of the poll "The Five Dysfunctions of a Team (Patrick Lencioni)," we found an intriguing positive correlation that warrants closer examination:  


0.1706 between the Avoidance of Accountability (Holding peers accountable is necessary for team success. Avoidance can lead to declining standards) and the Orange stage.

The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.1424. This positive correlation of 0.1706 meets the reliability criteria but does not necessarily imply causation. 


This positive correlation of 0.1706 makes sense, given Orange’s individualistic focus on personal accountability, skill-building, and merit-based advancement. In goal-driven Orange logic, every member should independently develop excellence to achieve team success.  

Avoiding accountability can feel protective in the short term but enables mediocrity. Constructive candor accelerates growth, even when uncomfortable. From Orange’s competitive view, holding peers accountable keeps standards high by incentivizing the best to excel.

Orange also correlates accountability avoidance with declining performance metrics—lower profits, lagging innovation, and inefficiencies from dead weight. For Orange, business outcomes speak louder. Qualitative harmony matters less than quantitative returns.

Finally, in Orange's philosophy, progress depends on being self-critical. Organizations and societies mature by spotlighting flaws, not obscuring them. Orange gains energy from identifying system bugs for optimization. The data guides the debugging.

In sum, Orange affiliation with peer accountability reflects its analytical belief in transparency, evidence, and self-correction as central to fulfilling one’s potential. Results rule. Broken should be unpacked, not masked.



In our analysis of the poll "What qualities and abilities do good leaders use when building successful teams?" we found an intriguing positive correlation that warrants closer examination:  


0.1235 between the Motivating and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0436. This positive correlation of 0.1235 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.1235 makes sense, as being able to motivate others aligns with several orange traits. Orange is achievement-oriented - focused on driving towards goals and results. They appreciate leaders who can rally their teams towards a shared vision through inspiration.


Orange psychology also values innovation and competence. Leaders who motivate by painting a compelling picture of how the team can grow, improve, and accomplish great things tap into Orange's ambitious spirit. 


However, Orange should beware of seeing motivation as just another tool to extract maximum performance. Authentic leadership requires genuine care for people as well as results.


Orange tends to be individualistic, so the communal nature of teamwork may need balancing. Strong motivation emerges from shared identity and purpose, not just personal gain.


This shows Orange's results-focused outlook prizes leaders who can energize teams. However, overreliance on raw motivation can lead to burnout. Sustainable achievement requires self-direction and alignment of values, not just passionate rallies. Nuance is key.



In our analysis of the poll "Does ageism exist?" we found an intriguing positive correlation that warrants closer examination:  


0.0952 between the No, ageism doesn't exist within my family and community and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0838. This positive correlation of 0.0952 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.0952 suggests that individuals aligned with the Orange value system are less likely to perceive ageism within their families and communities. Orange's focus on rationality, individualism, and achievement may lead to a view of people as autonomous actors judged by merit rather than age. 


Orange values progress and innovation. They may see age as less relevant than one's ability to contribute ideas and results. Traditional notions of respecting elders or deferring to seniority hold less sway. Competence trumps convention.


However, Orange should be cautious not to overlook subtle forms of age bias. Ageism can manifest in hiring practices, workplace culture, and media portrayals, even if not overt. A genuinely rational approach requires examining unconscious prejudices.


Orange's insight lies in valuing individual potential over categorical assumptions. But this must be balanced with awareness of systemic inequities. Reason and empathy can partner to create a society of equal dignity for all ages.



In our analysis of the poll "I live thinking about my past, present or future," we found an intriguing positive correlation that warrants closer examination:  


0.1082 between the Future and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0643. This positive correlation of 0.1082 meets the reliability criteria but does not necessarily imply causation. 



This positive correlation of 0.1082 makes sense since the Orange value system strongly emphasizes reason, science, technological advancement, and achieving goals through rational, analytical thinking. Individuals operating primarily from this worldview tend to be ambitious, goal-oriented, and driven by a desire for progress, efficiency, and results.


In this correlation, a future-oriented mindset aligns with Orange vMeme's focus on setting and striving towards objectives. By looking ahead and envisioning future possibilities, individuals at the Orange stage may be better equipped to apply logical reasoning, strategic planning, and scientific methods to achieve their desired outcomes.


Furthermore, the Orange value system's emphasis on individualism, self-reliance, and competition could contribute to a heightened focus on personal goals and ambitions, often requiring a forward-looking perspective to anticipate challenges, opportunities, and potential paths to success.



In our analysis of the poll "Empathy is," we found an intriguing negative correlation that warrants closer examination:  


-0.1154 between the Really listening to what others have to say / Strongly Agree and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0857. This negative correlation of -0.1154 meets the reliability criteria but does not necessarily imply causation.



This negative correlation of -0.1154 exceeds the critical value of 0.0586, meets the reliability criteria for further analysis, and could be explained by the Orange stage's focus on objective, analytical thinking and a potential tendency to prioritize task-oriented or outcome-driven approaches over interpersonal considerations.


The Orange value system's emphasis on individualism, self-reliance, and competitiveness could contribute to a mindset that places less importance on really listening to others, as it may be perceived as a less direct path to achieving personal goals or objectives.


Individuals at the Orange stage may be more inclined to view empathy through a more rationalistic lens, emphasizing understanding and addressing situations or problems through logical analysis rather than prioritizing the subjective experiences or emotional states of others. 



In our analysis of the poll "What makes people successful at work?" we found an intriguing negative correlation that warrants closer examination:  


-0.0691 between the Empathy and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0428. This negative correlation of -0.0691 meets the reliability criteria but does not necessarily imply causation. 



This negative correlation of -0.0691 exceeds the critical value of 0.0428, meets the reliability criteria for further examination, and could be explained by the Orange vMeme's focus on objective, analytical thinking and a potential tendency to prioritize task-oriented or outcome-driven approaches over interpersonal considerations.


The Orange value system strongly emphasizes reason, science, technology, and achieving goals through rational, logical thinking and applying scientific methods. Individuals operating primarily from this worldview tend to be ambitious, goal-oriented, individualistic, and competitive, valuing independence, progress, efficiency, and results.


Individuals at the Orange stage may be more inclined to view success through the lens of measurable results, efficiency, and the application of logical reasoning or scientific methods rather than prioritizing the subjective experiences or emotional states of others.


Additionally, the Orange value system's emphasis on individualism, self-reliance, and competitiveness could contribute to a mindset that places less importance on empathy, as it may be perceived as a less direct path to achieving personal goals or objectives in the workplace.



In our analysis of the poll "Ageism in Life," we found an intriguing negative correlation that warrants closer examination:  


-0.1750 between the I notice ageism in personal life and the Orange stage.

The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0858. This negative correlation of -0.1750 meets the reliability criteria but does not necessarily imply causation. 


This negative correlation of -0.1750 is statistically significant, surpassing the critical value of 0.0858. Individuals more aligned with the Orange value system may be less likely to perceive or be affected by ageism in their personal experiences. 

This could be due to a few potential factors:
  1. The Orange stage's emphasis on meritocracy and individual achievement may lead to a belief that age is less relevant than one's abilities and accomplishments.
  2. The rational, analytical mindset of the Orange stage may make individuals less attuned to the nuances of interpersonal dynamics and social biases.
  3. The Orange stage's focus on progress and efficiency may prioritize objective performance measures over subjective perceptions of age-related discrimination.
This negative correlation highlights a potential disconnect between the Orange stage's emphasis on reason and ageism's more subjective, interpersonal nature. Individuals in the Orange stage may be less inclined to recognize or be affected by ageism in their personal lives, potentially due to their focus on individual achievement and reliance on rational, scientific approaches to problem-solving.

The Orange value system is focused on reason, science, and technology. Individuals in this stage are ambitious, goal-oriented, and driven by a desire for knowledge and understanding. They value progress, efficiency, and results and use rational, logical thinking and scientific methods to achieve their objectives.


In our analysis of the poll "Reasons why people give up," we found an intriguing negative correlation that warrants closer examination:  


-0.0946 between the Feel they have something to lose and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0592. This negative correlation of -0.0946 meets the reliability criteria but does not necessarily imply causation.  



This negative correlation of -0.0946 suggests an inverse relationship between the feeling of having something to lose as a reason for giving up and the Orange stage. Individuals operating within the Orange value system tend to exhibit a lower association with attributing their tendency to give up to a fear of losing something.


From the Orange value system's lens, this negative correlation reflects the focus on achieving goals and objectives through logical reasoning and the application of scientific methods.


Those in the Orange stage may be more inclined to approach challenges and obstacles from a rational and analytical perspective rather than being deterred by the potential for loss or setbacks. The Orange worldview values progress, efficiency, and results, often prioritizing forward momentum and pursuing knowledge over concerns about potential risks or sacrifices.


The Orange value system emphasizes individualism, self-reliance, and a competitive spirit. Individuals operating within this value system may be less likely to perceive the possibility of loss as a significant deterrent, as they tend to strongly believe in their ability to overcome challenges through their efforts and the application of rational problem-solving techniques.


However, it is essential to note that this negative correlation does not necessarily imply a complete disregard for potential risks or consequences within the Orange value system. Instead, it may reflect a tendency to approach decision-making and goal-setting more objectively and analytically, weighing the potential benefits against the costs or losses logically and systematically.


In addressing the issue of perseverance and overcoming the tendency to give up, it may be beneficial to integrate elements of the Orange value system, such as promoting critical thinking, encouraging data-driven decision-making, and fostering a culture of continuous learning and adaptation. At the same time, it is essential to balance these elements with an understanding of the emotional and psychological factors that can influence human behavior, ensuring a well-rounded approach to achieving personal and professional goals.



In our analysis of the poll "How Do You Regulate Your Emotions? (by Nawal Mustafa [1])" (When I feel REJECTED. I will acknowledge that this feeling sucks, but I will not let it consume me), we found an intriguing negative correlation that warrants closer examination:  


-0.3599 between the Rejection is redirection / Moderately Disagree and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.2385. This negative correlation of -0.3599 meets the reliability criteria but does not necessarily imply causation.



This negative correlation of -0.3599 suggests an inverse relationship between moderately disagreeing with the notion that "rejection is redirection" when dealing with feelings of rejection and individuals operating within the Orange stage of value system development. Those aligned with the Orange worldview tend to exhibit a lower association with this particular approach to emotion regulation.


Individuals in the Orange stage may perceive "rejection is redirection" as overly symbolic or lacking concrete, rational justification. The Orange worldview values logical reasoning, scientific methods, and a reliance on empirical evidence, which could lead to a dismissal of more abstract or philosophical approaches to emotional regulation.


Furthermore, the Orange value system emphasizes individualism, self-reliance, and a competitive drive for achievement and progress. Reframing rejection as a redirection is a coping mechanism that potentially undermines personal agency and the ability to overcome obstacles through sheer determination and rational problem-solving.


However, it is essential to note that this negative correlation does not necessarily imply a complete disregard for emotional well-being or the importance of emotion regulation within the Orange value system. Instead, it may reflect a preference for more direct, pragmatic, and evidence-based approaches to managing emotions, aligning with the Orange worldview's emphasis on reason, efficiency, and tangible results.


From the lens of the Orange value system, this correlation reflects the focus on pragmatism, empiricism, and the pursuit of tangible, measurable results.



In our analysis of the poll "The main priorities of job seekers," we found an intriguing positive correlation that warrants closer examination:  


0.1248 between the Career opportunities and the Orange stage.


The critical value of the correlation coefficient for a normal distribution, by William Sealy Gosset (Student) r = 0.0647. This positive correlation of 0.1248 meets the reliability criteria but does not necessarily imply causation.



This positive correlation of 0.1248 could be explained from the perspectives of companies, teams, and individuals operating within the Orange value system, emphasizing reason, science, technology, progress, efficiency, and rational, logical thinking.


1) From the perspective of companies operating within the Orange value system:


This positive correlation suggests a relationship between companies aligned with the Orange worldview and their recognition of career opportunities as a priority for job seekers. Companies may strongly emphasize providing clear professional growth and advancement paths, aligning with the Orange value system's focus on achievement, progress, and tangible results.


2) From the perspective of teams operating within the Orange value system:


This positive correlation indicates a higher association between teams operating within the Orange stage of value system development and their acknowledgment of the importance of career opportunities for attracting and retaining talent. For these teams, driven by a desire for knowledge, efficiency, and the application of scientific and technological methods, offering opportunities for professional development and career advancement may be a critical factor in fostering a motivated and high-performing workforce.


3) From the perspective of individuals within the Orange value system:


This positive correlation suggests that individuals aligned with the Orange worldview tend to emphasize career opportunities more when evaluating potential job prospects. For these individuals, rooted in a rational, analytical, and goal-oriented mindset, the ability to progress in their careers, acquire new knowledge, and achieve tangible results is paramount.


It is important to note that this positive correlation does not necessarily imply disregarding other factors, such as compensation or work-life balance, within the Orange value system. Instead, it may reflect a recognition that career opportunities, professional growth, and the ability to learn and advance continuously are vital components of personal and professional fulfillment within this value system.


In addressing issues related to talent acquisition, employee engagement, and fostering a motivated and productive workforce, it may be beneficial for companies, teams, and individuals to incorporate elements of the Orange value system, such as promoting continuous learning opportunities, providing clear paths for career advancement, and fostering a culture of achievement and progress. By acknowledging and accommodating the Orange value system's unique perspective, organizations can develop strategies aligning with their values while ensuring a balance between individual growth, team cohesion, and overall organizational success.
