Have you ever heard of the tenth-man rule? This concept suggests that, if nine out of ten people in a group agree on an issue, the tenth person should adopt an opposing viewpoint, assuming the majority could be wrong. This strategy, illustrated in the movie “World War Z”, was adopted by Israeli intelligence after after their failures to recognize improbable threats, such as the imminent danger posed by the zombie apocalypse. The 1973 Yom Kippur War is the best example of this learning curve, for when they intercepted an extravagant warning of the existence of the undead, a ten-man council met to discuss the matter. Their approach was straightforward:
If nine members reached the same conclusion based on the information received, the tenth member was tasked with disagreeing on the matter. No matter how improbable the case may seem. By taking this opposing stance, the tenth man would assume that the other nine might be mistaken, helping to maintain a critical and balanced discussion within thethe group.
According to Irving Janis (1982), groupthink is a popular psychological phenomenon. The more cohesive a group is, the more likely it is to sacrifice critical thinking for the sake of harmony. However, at TAGDit we believe that it’s crucial to listen to the individual who dares to challenge the group’s consensus because they may identify weaknesses or alternative strategies that others have overlooked.
This tenth-man or devil’s advocate requires a specific type of personality, requires a specific personality type. This role typically demands a propensity for making unsolicited counterarguments that oppose prevailing opinions. According to the big five personality traits, lower levels of agreeableness and negative emotions may be advantageous in this context. Additionally, a high level of openness to experience—defined by a keen interest in new ideas—may help in formulating opposing views and synthesizing the information at hand.
Ultimately, a devil’s advocate must possess more than critical thinking skills. They also need courage, motivation, and assertive communication to highlight the less popular aspects of an argument and identify its flaws. Regardless of the outcome, the goal is to effectively persuade their colleagues and illuminate the weaknesses in the prevailing viewpoint. This role represents a form of inverted thinking, as it plays on the eternal conflict between the individual and the group.


Innovation management
We live in a time of rapid and constant change. Each day brings new knowledge, products, and innovative ways of doing things.While understanding these advancements can be challenging, they also present us with incredible opportunities.
In the world of business innovation, various groups work together such as the Innovation and Business Intelligence Team, Strategic Customer Service Networks, Sourcing, Procurement and Supply Chain Management, Engineering and Design Teams, and individual program areas. This multidisciplinary community facilitates the evaluation and adoption of high-value innovations that enhance the quality of customer experiences. But how do they do this? By developing decision intelligence support tools, that empower and optimize decision-making within the organization.
The tenth man rule aims to balance pathological group cohesion with heroic individual dissent. Thought it might seem exaggerated, concept highlights the potential for improved alternatives. Ultimately, the steadfast individual within the group becomes a beacon of insight, capable of identifying and correcting the imperfections in majority decisions, ensuring that innovation thrives.
Red Team
Red Team Analysis lets you fully leverage an adversarial approach without relying on a single individual,It’s a form of devil’s advocacy that puts a team in the shoes of a competitor. The goal is to uncover and exploit the competitor’s weaknesses in their business model. Unlike traditional devil’s advocacy, red teaming operates discreetly, fostering a spirit of healthy competition among those dedicated to making informed decisions and those eager to showcase the potential pitfalls of those choices.
Red team analysis allows you to better understand a counterpart’s strategy, anticipate their next move and prepare accordingly. Like any worthwhile endeavor, mastering this skill takes time and practice. Let’s explore its application at organizational level. everyday life.
What is Red Team Analysis?
Red team analysis, also known as red teaming, is a powerful analytical technique that seeks to emulate the thoughts and actions of an adversary. The objective is to examine the plans, processes and internal dynamics of another group or organization, shining a light on often overlooked links in decision-making. This approach has its origins in the military, but has become standard practice in intelligence analysis as well. Here, we will draw upon a simplified version described in the CIA’s Tradecraft Primer.
At its core, Red Teaming involves a change of perspective within the enterprise. Typically, an analyst views situations through the lens of their own community— blue team. As the name suggests, Red Team Analysis invites analysts to step into the shoes of the opposing team, transforming them from mere observers to active participants in understanding the adversary’s world.
The method is particularly valuable when engaging with counterparts from different culture, beliefs, and mindset. It serves as a reminder that one cannot assume adversaries will respond as one would. Red team analysis attempts to overcome this bias by assembling a specialized team to adopt perspectives divergent from the organization or the majority. Yet, immersing oneself in the adversary’s world is harder than it sounds. Hence, the Devils Business Advocate will review new invention disclosures, assess the need and develop IP protection strategies that pave the way for commercialization efforts informed by this insightful analysis.
What You Will Get:
The Other Side of the Coin
Introducing intentional forms of dissent can spark new insights but also potential internal conflicts. Therefore, consider and reflect on a few key questions:
- Where is the boundary between constructive disagreement and reckless indiscretion?
- What if your devil’s advocacy becomes destructive, leaving decision-makers without viable options and stifling their ability to act?
- How much of your limited resources are you willing to use? How far-fetched does an objection have to be to be considered a waste of time?
- How prepared is everyone to embrace challenges to their assumptions?
- How are you going to manage the potential emotional fallout from bruised egos if ideas continue to be rejected?
Even well-structured devil’s advocacy can easily degrade into a mere box-ticking exercise undermining its original purpose. If participants begin to feel that the exercise only benefits the designated devil, it could impact the confidence in the whole process. Ultimately, there are informal social sanctions for anyone who takes this whole devil thing too seriously. Think of it as an autoimmune group reaction to ostracize “Lucifer’s advocate.”
Final Considerations
The “tenth man rule” is an unconventional approach to to identifying weaknesses in an organization’s decision making process. It is not a mere contradiction. Mephisto’s spokesperson should understand how to express disagreement in a justified, informed and constructive manner. If critical thinking is sacrificed or overlooked, an outsider could reveal these weaknesses. However, it is likely that this outsider will not have your organization’s best interests at heart.
