The 3 Vital Rules of Science: What They Are and Why They Matter

Introduction
Ever wonder why some "scientific" claims sound convincing but fall apart under scrutiny? Science isn’t just a collection of facts—it’s a disciplined process for understanding the world. In today’s flood of information and competing claims, being fluent in the logic and rigor of science is more valuable than ever.
Scott M. Graffius shared a visual—similar to the one that heads-up this article—via social media. It garnered attention from professionals across disciplines. Prompted by the interest it generated, Graffius developed this article to provide deeper insight into the concepts behind the visual: falsifiability, replicability, and the critical distinction that correlation is not causation.
These principles are foundational to the scientific method and are frequently misunderstood. Together, they offer a powerful lens for evaluating claims, research rigor, and the validity of conclusions.

Falsifiability
Falsifiability means a scientific claim or hypothesis must be testable—and potentially provable wrong. Championed by philosopher Karl Popper, this idea is essential to science’s integrity. For example, “All swans are white” is falsifiable: a single black swan disproves it. In contrast, vague claims like “This crystal boosts your energy in ways science can’t measure” aren’t science. Falsifiability ensures ideas are grounded in evidence, not just belief or anecdote.
A real-world example is Einstein’s theory of general relativity. Einstein predicted that massive objects like the sun could bend light—a bold, falsifiable claim. In 1919, during a solar eclipse, astronomers led by Arthur Eddington tested this by observing starlight bending around the sun, exactly as Einstein predicted. If the light hadn’t bent, the theory could have been disproven—a hallmark of true science. This ability to be tested and potentially refuted sets scientific claims apart from pseudoscience or speculation.

Replicability
Replicability means an experiment or study should yield the same results when repeated under identical conditions. It’s how science builds trust and advances. If a finding can’t be replicated, its reliability is questionable. The “replication crisis” in fields like psychology and medicine has highlighted this principle, as many high-profile studies failed to hold up when retested.
A notable case is a 2011 study on “ego depletion,” which suggested that self-control draws from a limited pool of mental energy, reducing the ability to exert it elsewhere. The idea gained traction, influencing workplace productivity strategies and personal development advice. For example, people were advised to tackle tough tasks early to “save” mental energy. Yet, a 2016 large-scale replication effort with over 2,000 participants across multiple labs failed to reproduce the effect. This raised doubts about the validity of ego depletion and underscored the need for replication to distinguish genuine insights from flawed findings.
Replicability isn’t about perfection—it’s about transparency, rigor, and enabling the scientific community to verify and build on discoveries.

Correlation is Not Causation
One of the most misunderstood principles in science and statistics is the difference between correlation and causation. Just because two things occur together doesn’t mean one causes the other.
In the business world, a notable example involves the assumption that implementing employee wellness programs directly leads to improved company performance. Early studies observed that companies with such programs often reported better financial outcomes, leading to the belief that the wellness initiatives were the cause of this success. However, subsequent research, including a comprehensive randomized controlled trial conducted by the University of Chicago and Harvard University, found that while wellness programs might encourage some healthy behaviors, they did not significantly impact clinical health measures, healthcare spending, or job performance. This suggests that the initial correlation was likely influenced by other factors, such as the possibility that more successful companies have more resources to invest in wellness programs, rather than the programs themselves driving financial success. This example underscores the importance of not conflating correlation with causation.
By contrast, science can confirm causation. Take regular exercise: decades of research, from randomized trials to longitudinal studies, show it directly boosts cardiovascular health. Aerobic activity strengthens the heart, lowers blood pressure, and cuts heart disease risk—effects backed by clear biological evidence. Distinguishing correlation from causation is critical, as mistaking one for the other can lead to flawed conclusions, poor policies, and misleading headlines. Sound science digs deeper, using experiments and analysis to uncover cause-and-effect relationships.
Conclusion
The scientific method thrives on curiosity but demands discipline. Falsifiability, replicability, and the distinction between correlation and causation aren’t just academic concepts—they’re practical tools for critical thinking. Whether evaluating research, assessing a health claim, or analyzing business data, these rules help separate the meaningful from the merely suggestive. Embrace these principles, and you’ll not only navigate today’s flood of information with confidence but also inspire others to think critically in a world that needs it more than ever.

PMI’s Infinity AI Gets the Basics of Team Development Alarmingly and Repeatedly Wrong
17 June 2025
BY SCOTT M. GRAFFIUS | ScottGraffius.com

If there's an update after this article is published, the information will appear in the Post-Publication Notes section.

Introduction
When an artificial intelligence product is released under the banner of the Project Management Institute (PMI)—a globally recognized authority on project management—it carries the weight of authority. PMI’s Infinity™ 2.0, marketed as an AI assistant to support professionals, should meet or exceed the accuracy of the PMI’s materials, especially on core topics such as team development.
Unfortunately, it does not.
This article reports how PMI Infinity performed when asked a basic question about a foundational concept in project management: the phases of team development (also known as the stages of team development, team dynamics, group dynamics, etc.). The result is a case study in misstatement, backpedaling, and conceptual fuzziness that would be unacceptable in a project management 101 course—let alone from a product designed to represent the PMI.
The Context: Team Development is Not Optional in Project Management
Bruce Tuckman’s 1965 model of team development—comprised of forming, storming, norming, and performing—was expanded in 1977 with colleague Mary Ann Jensen to include adjourning. These five phases are a well-established staple in organizational behavior, leadership studies, and—critically—project management.
PMI itself integrates Tuckman’s model into its materials. Project teams do not operate in a vacuum. Understanding how they form, clash, align, deliver, and disband is essential to project success. The project manager’s job is to navigate that lifecycle.
Failure in this area by PMI Infinity AI is not a minor glitch. It’s a foundational error, and it happened not just once but across multiple responses.
The Timeline of Errors: A Blow-by-Blow Breakdown
Here’s how PMI's Infinity AI handled the queries about team development, step by step (the detailed transcript is available in text format and screen shot format):
1. Omission of Adjourning in the Initial Answer
In the first response, PMI Infinity lists:
That’s it.
Adjourning—the critical fifth stage added in 1977—is not on the list. This is a fundamental factual error. Tuckman and Jensen's 1977 update has been in existence for 48 years. The AI’s failure to include it is inexcusable.
2. “Adjourning/Reforming” is a Fabricated Concept
Later, the AI refers to the last phase as “Adjourning/Reforming.”
This hybrid phrase does not originate from Tuckman or Tuckman/Jensen. It’s not a dual label. Adjourning is the correct term, and it has a specific meaning: the disbanding of the team. While teams can regroup in the future, Tuckman never inserted “reforming” as a part of the developmental progression.
This error is especially egregious because it fabricates terminology under the guise of authority. PMI Infinity is not just being sloppy—it’s making things up.
3. Misleading Framing of Adjourning
Even when the AI agrees with its error, corrects itself, and then uses the proper term (adjourning), it frames the phase as:
“... acknowledging the lifecycle of a team beyond the completion of a project.”
This phrasing is incomplete and misleading. It suggests that adjourning only occurs when a project is completed, ignoring the fact that teams may otherwise adjourn due to:
Reducing adjourning to “after completion” is not just simplistic—it’s incorrect. In real-world project management, teams disband for many reasons. This is not nuance; it’s the reality of the profession.
4. Only After Multiple Prompts Does the AI Yield an Accurate Answer
The AI repeatedly ignored facts and fabricated facts. Such AI errors are termed "hallucinations." Only because the user was an expert on the subject matter, there was several rounds of feedback and corrections.
An AI that needs to be corrected repeatedly, with escalating specificity, to get a basic, textbook-level answer right is not ready for professional use.
Why This Matters: The Cost of Getting It Wrong
The team development model is part of the behavioral bedrock of leadership, communication, and team performance. If PMI Infinity can’t reliably explain the phases of team development:
This is a serious, material issue. Misinformation at the foundational level breeds misunderstanding and downstream failure.
Final Scorecard
On a scale of 1-10 (where 10 is best), here's the rating of the performance of PMI's Infinity AI tool:
Conclusion: A Wake-Up Call for PMI and Users of PMI's Infinity AI
PMI Infinity AI failed to provide accurate, complete, and credible information on one of the most fundamental topics in project management. This should concern every professional who uses the tool.
Team development is not a minor topic. It is a core competency area covered in PMI publications and lived daily by project managers worldwide. For PMI’s AI to fumble this topic so spectacularly and repeatedly is not just ironic—it’s alarming.
Until significant improvements are made, PMI Infinity AI should only be used with extreme caution—and only with the user independently verifying information from reliable sources. When AI incorporates facts, it can be a powerful tool. When AI disregards facts or fabricates facts, it’s a threat. Alarmingly, PMI Infinity AI has shown that it repeatedly disregarded facts and fabricated facts.

Introduction
When an artificial intelligence product is released under the banner of the Project Management Institute (PMI)—a globally recognized authority on project management—it carries the weight of authority. PMI’s Infinity™ 2.0, marketed as an AI assistant to support professionals, should meet or exceed the accuracy of the PMI’s materials, especially on core topics such as team development.
Unfortunately, it does not.
This article reports how PMI Infinity performed when asked a basic question about a foundational concept in project management: the phases of team development (also known as the stages of team development, team dynamics, group dynamics, etc.). The result is a case study in misstatement, backpedaling, and conceptual fuzziness that would be unacceptable in a project management 101 course—let alone from a product designed to represent the PMI.
The Context: Team Development is Not Optional in Project Management
Bruce Tuckman’s 1965 model of team development—comprised of forming, storming, norming, and performing—was expanded in 1977 with colleague Mary Ann Jensen to include adjourning. These five phases are a well-established staple in organizational behavior, leadership studies, and—critically—project management.
PMI itself integrates Tuckman’s model into its materials. Project teams do not operate in a vacuum. Understanding how they form, clash, align, deliver, and disband is essential to project success. The project manager’s job is to navigate that lifecycle.
Failure in this area by PMI Infinity AI is not a minor glitch. It’s a foundational error, and it happened not just once but across multiple responses.
The Timeline of Errors: A Blow-by-Blow Breakdown
Here’s how PMI's Infinity AI handled the queries about team development, step by step (the detailed transcript is available in text format and screen shot format):
1. Omission of Adjourning in the Initial Answer
In the first response, PMI Infinity lists:
- Forming,
- Storming,
- Norming, and
- Performing.
That’s it.
Adjourning—the critical fifth stage added in 1977—is not on the list. This is a fundamental factual error. Tuckman and Jensen's 1977 update has been in existence for 48 years. The AI’s failure to include it is inexcusable.
2. “Adjourning/Reforming” is a Fabricated Concept
Later, the AI refers to the last phase as “Adjourning/Reforming.”
This hybrid phrase does not originate from Tuckman or Tuckman/Jensen. It’s not a dual label. Adjourning is the correct term, and it has a specific meaning: the disbanding of the team. While teams can regroup in the future, Tuckman never inserted “reforming” as a part of the developmental progression.
This error is especially egregious because it fabricates terminology under the guise of authority. PMI Infinity is not just being sloppy—it’s making things up.
3. Misleading Framing of Adjourning
Even when the AI agrees with its error, corrects itself, and then uses the proper term (adjourning), it frames the phase as:
“... acknowledging the lifecycle of a team beyond the completion of a project.”
This phrasing is incomplete and misleading. It suggests that adjourning only occurs when a project is completed, ignoring the fact that teams may otherwise adjourn due to:
- Project cancellation,
- Restructuring,
- Budget cuts,
- Organizational shifts, or
- Other related situations.
Reducing adjourning to “after completion” is not just simplistic—it’s incorrect. In real-world project management, teams disband for many reasons. This is not nuance; it’s the reality of the profession.
4. Only After Multiple Prompts Does the AI Yield an Accurate Answer
The AI repeatedly ignored facts and fabricated facts. Such AI errors are termed "hallucinations." Only because the user was an expert on the subject matter, there was several rounds of feedback and corrections.
An AI that needs to be corrected repeatedly, with escalating specificity, to get a basic, textbook-level answer right is not ready for professional use.
Why This Matters: The Cost of Getting It Wrong
The team development model is part of the behavioral bedrock of leadership, communication, and team performance. If PMI Infinity can’t reliably explain the phases of team development:
- How can it be trusted to assist professionals under deadline pressure?
- How will it guide students or others trying to build foundational knowledge?
- What confidence can any user have that more complex questions will yield credible results?
This is a serious, material issue. Misinformation at the foundational level breeds misunderstanding and downstream failure.
Final Scorecard
On a scale of 1-10 (where 10 is best), here's the rating of the performance of PMI's Infinity AI tool:
- Factual Accuracy: 1/10
- Alignment with PMI Materials: 1/10
- Terminological Precision: 1/10
- Responsiveness to Correction: 5/10
- Professional Use Readiness: 1/10
- Overall Score: 1/10
Conclusion: A Wake-Up Call for PMI and Users of PMI's Infinity AI
PMI Infinity AI failed to provide accurate, complete, and credible information on one of the most fundamental topics in project management. This should concern every professional who uses the tool.
Team development is not a minor topic. It is a core competency area covered in PMI publications and lived daily by project managers worldwide. For PMI’s AI to fumble this topic so spectacularly and repeatedly is not just ironic—it’s alarming.
Until significant improvements are made, PMI Infinity AI should only be used with extreme caution—and only with the user independently verifying information from reliable sources. When AI incorporates facts, it can be a powerful tool. When AI disregards facts or fabricates facts, it’s a threat. Alarmingly, PMI Infinity AI has shown that it repeatedly disregarded facts and fabricated facts.
