Like Jamie Dimon, AT&T CEO says if you attend a meeting, you need to show up prepared—he ‘craves’ people who don’t just sit back and observe | Fortune

Stankey, at the helm of one of the world’s largest telecommunications companies, articulated his stance during a recent joint interview with JPMorgan Chase CEO Jamie Dimon, hosted by LinkedIn. "I love discourse," Stankey declared, emphasizing his belief that vigorous debate is essential for sound decision-making and innovation. He further elaborated that a foundational principle embedded within AT&T’s cultural documents explicitly mandates employees to arrive at meetings having done their "homework." This isn’t merely a suggestion; it’s a core expectation.

"Don’t walk in there and just be an observer," Stankey urged, highlighting the imperative for active engagement. He stressed that any viewpoint shared should not be a mere "uninformed opinion" but rather "a point of view that’s built on facts, information, and data. I crave that." This demand for evidence-based contributions reflects a strategic imperative to combat groupthink and ensure that critical decisions are underpinned by rigorous analysis rather than untested assumptions or consensus-seeking for its own sake. Stankey went so far as to suggest that if employees are unwilling to speak up or lack a constructive point to make, it might indicate that the "right people" are not present in the room – a stark implication for individual accountability and team composition.

This leadership ethos resonates deeply with Jamie Dimon, the veteran chief of JPMorgan Chase, who has long championed the importance of productive and necessary meetings. Dimon firmly believes that leaders must cultivate an environment where employees feel psychologically safe enough to disagree, challenge conventional wisdom, and even raise "uncomfortable issues"—a practice he famously metaphorized as "putting the proverbial dead cat on the table." This blunt expression signifies the necessity of addressing unpleasant realities head-on, no matter how difficult, rather than allowing them to fester and undermine organizational health.

Dimon’s commitment to open critique is personal: "I am never upset when someone says I’m wrong about something," he stated, clarifying that his ultimate objective is to achieve the best possible outcomes for his clients, the country, and the company. This willingness to be challenged is a hallmark of effective leadership, fostering trust and encouraging subordinates to contribute their honest assessments without fear of retribution. It creates a feedback loop essential for continuous improvement and strategic agility.

However, the efficacy of this leadership strategy has yielded divergent results for the two corporate giants in the recent past. Over the last year, JPMorgan Chase’s stock has seen a robust increase of more than 17%, reflecting strong market confidence and successful strategic execution under Dimon’s leadership. In stark contrast, AT&T’s stock has experienced a decline of approximately 12% over the same period, signaling investor concerns amidst its ongoing transformation efforts and intense competition in the telecommunications sector. While stock performance is influenced by myriad factors beyond leadership style, the market’s perception of strategic clarity and execution undoubtedly plays a significant role, perhaps suggesting that while the philosophy of open discourse is sound, its implementation and impact vary greatly depending on organizational context, market conditions, and the broader strategic landscape.

Rethinking Meeting Preparation in the Age of AI

Beyond the imperative for active participation, both Fortune 500 CEOs also delved into how they are adapting their meeting preparation strategies in the rapidly evolving age of artificial intelligence. Traditionally, both executives have been staunch advocates for diligent pre-reading of materials as a cornerstone of preparedness. However, the advent of sophisticated AI tools is prompting them to reconsider the most efficient methods for information assimilation.

"I’m starting to wonder if reading is the best way to go," Stankey mused, indicating a potential paradigm shift. He elaborated, "As I’ve gotten more into the dialog dynamic with AI, I can consume, I think, faster now in a directed conversation." This observation points to AI’s capacity to summarize complex documents, answer specific questions, and facilitate a more interactive and personalized learning experience, potentially accelerating the comprehension process beyond what traditional linear reading offers. For a CEO managing the vast complexities of a global telecommunications company, any tool that enhances information intake speed and depth holds immense value.

Dimon echoed Stankey’s sentiment, confirming his adoption of similar AI-driven practices. "I do that same thing," Dimon affirmed. "I use Gemini or Google, and deep dive to get information very quickly. I try to do all my previews before I go to meetings." This shared embrace of AI for rapid, targeted information retrieval underscores a pragmatic approach to leveraging technology to maintain peak efficiency in demanding leadership roles. It demonstrates a willingness to innovate not just in core business operations, but also in personal productivity and cognitive processes.

Crucially, while the methods of preparation are evolving, the underlying principle remains inviolable: showing up prepared is non-negotiable. Dimon has consistently articulated this throughout his career. At Fortune’s Most Powerful Women conference last year, he emphasized, "When I go to a meeting, I’ve done the pre-reads, and you get 100% of my attention." For Dimon, preparedness is intertwined with respect—respect for others’ time, respect for the agenda, and respect for the importance of the decisions at hand. He views distraction, such as checking emails or phones during meetings, as a sign of disrespect that undermines productivity and the collective effort. Consequently, Dimon has long advocated for eliminating meetings altogether when they are deemed unnecessary or fail to be a productive use of employees’ valuable time, reflecting a ruthless efficiency that has become a hallmark of his leadership style.

Dimon’s Enduring Ethos vs. Stankey’s Modern Demand

Dimon’s thoughtful approach to meeting etiquette is not a recent development but a philosophy he has cultivated over his entire career. An early Fortune profile of Dimon, then a 28-year-old Harvard MBA serving as an assistant to American Express president Sanford "Sandy" Weill, offered a glimpse into his nascent professional principles. At that nascent stage of his career, Dimon believed his most effective role was often to observe, learn, and absorb information rather than immediately interjecting. "My first goal was to learn something and not say anything until I could add some value," Dimon recounted at the time. This prudent approach allowed him to develop a comprehensive understanding of complex situations before offering his insights, a strategy that served him well in his ascent through the financial world.

However, this foundational mantra from a young Dimon might face a different reception in John Stankey’s contemporary conference room. While Dimon’s early career focus was on adding value when he spoke, Stankey’s current expectation is for everyone to arrive with a "point of view" built on facts and data. A young Dimon, prioritizing learning over immediate contribution, might find himself subject to Stankey’s "cold-call" approach, expected to articulate an informed perspective rather than simply soaking everything in. This highlights a fascinating tension between different stages of professional development and the evolving demands of executive leadership. While learning through observation is crucial, modern high-stakes corporate environments often demand proactive, evidence-based contributions from all participants.

The Broader Implications: Fostering a Culture of Constructive Dissent

The insights from Stankey and Dimon extend beyond mere meeting protocols; they illuminate a fundamental aspect of organizational health and strategic resilience. In today’s volatile, uncertain, complex, and ambiguous (VUCA) business environment, the ability to make rapid, informed decisions is paramount. A culture that stifles dissent or rewards conformity is inherently fragile.

This approach aligns with academic research on organizational psychology and leadership. Professor Amy Edmondson of Harvard Business School, for instance, has extensively researched the concept of "psychological safety"—a shared belief that the team is safe for interpersonal risk-taking. In environments with high psychological safety, employees feel comfortable speaking up, asking questions, and even admitting mistakes, knowing they won’t be punished or humiliated. Stankey and Dimon, by actively soliciting diverse perspectives and welcoming disagreement, are implicitly striving to cultivate this psychological safety, which is critical for innovation, error detection, and continuous learning.

The "yes-men" phenomenon, conversely, leads to "groupthink," a psychological phenomenon where groups strive for conformity and harmony, resulting in irrational or dysfunctional decision-making. History is replete with examples of corporate failures stemming from a lack of critical challenge to prevailing ideas. By demanding data-backed discourse, Stankey aims to inoculate AT&T against this common organizational malady. Similarly, Dimon’s insistence on "putting the dead cat on the table" is a direct antidote to the polite avoidance of uncomfortable truths that can derail even the most promising strategies.

Implementing such a culture, especially in large, established organizations like AT&T and JPMorgan Chase, is not without its challenges. It requires sustained effort from leadership to model the desired behavior, actively listen to diverse opinions, and visibly reward constructive input. It also demands that employees develop the critical thinking skills, data literacy, and communication prowess to articulate their perspectives effectively and respectfully. The shift from passive observation to active, informed participation represents a significant cultural transformation, requiring investment in training, clear communication of expectations, and a consistent reinforcement mechanism.

In conclusion, the shared wisdom of John Stankey and Jamie Dimon offers a powerful blueprint for effective leadership in the 21st century. Their emphasis on informed discourse, the rejection of uncritical conformity, and the pragmatic adoption of AI for enhanced preparedness underscore a profound understanding of what it takes to navigate complex business landscapes. While their companies’ recent stock performances present a mixed picture of their respective journeys, the underlying philosophy—that success hinges on courageous, data-driven conversations—remains a timeless truth, continually adapting to the evolving tools and demands of the modern corporate world. The days of simply showing up to a meeting are over; today’s leaders expect you to show up, speak up, and back it up.
