What in the Fu&^ing Sh#$ is Leadership? Pt.III – The Big Five Leadership Styles In 2026

We’ve Made It to Modern Day Leadership Theories

In Pt.2 we went through the classical leadership styles and discussed the concept of both transactional and transformative styles being needed in an organization to be an effective manager, leader, boss, or supreme facilitator.

Effective leadership necessitates diversity in style and flexibility of response options.

As we look at modern leadership theories, understand that leadership studies has morphed from defining one leader in totality to dissecting the styles they use and the contexts they use them in.

Allegorically, we’re not defining the plumber. We’re defining the tools they use, the ways they use them, and the jobs in which the tools are useful. In this way, picking one of these styles and embodying it alone as the sole guiding light for your future actions is about as useful as trying to solve all problems with just a hammer.

In this final research-based installment, we’re going to review the current landscape of the top five prevalent leadership styles.

As always, I did way more research and writing than I needed to. And therefore I’m front loading the good stuff and am including all leadership styles up to this point as well. Feel free to save this post as a handy guide because I have painstakingly matched each leadership style known to me to its seminal primary source.

Let’s get to it.

The Big 5 Styles

1. Adaptive Leadership (Heifetz, 1994)

Adaptive leadership was introduced in 1994 in a book called Leadership Without an Easy Answer from Ronald Heifetz. Ronald was at Harvard’s Kennedy School of Government working in the public leadership space and he noticed that many leaders were trying to solve problems with authority and expertise when the real work required people to change their values, behaviors, and expectations.

Some problems can’t be solved by leaders, only by helping people change.

(Source: Ronald Heifetz, 2021)

Ronald argues that it comes down to helping people survive and overcome the complexities of reality when reality refuses to cooperate. Adaptive leadership starts by asserting a distinction:

there are technical challenges and there is everything else.

Technical challenges have binary and numbers-based answers. If we spend $X or work on it for Y-hours, or we call up Craig, then the problem is solved. (Everyone needs a Craig, they make the world go around.)

The “everything else” problems, Adaptive problems, don’t have a straightforward solution easily solved through money, time, or the knowledge of a technical expert. The underlying problem is unclear, there is no ready solution, and people themselves have to change in order to get a win.

Technical Problems

1. “The server is down.” —> Call Craig from IT.
2. “Our manufacturing line has a bottleneck”
3. “We need to change our process to meet a regulatory requirement”
4. “We need to develop a vaccine”
5. “The Espresso Machine is broken”

Adaptive Problems

1. There are silos between our teams.
2. Global Warming and Climate Science.
3. AI adoption and automation.
4. Remote/Hybrid Work.
5. Low Psychological Safety.
6. Burnout Culture.

Observe again that all technical problems can be solved by consulting a technical expert and throwing time and money at the problem. For Adaptive problems, the solution is abstract and multifaceted and we often lack the skills to address these problems. (Shout out Kestryl Edge LLC, this is the entire reason we exist).

(Source: The Heffelfinger Company, 2021)

We know there are silos, and we agree collaboration is good. But no one will change behavior without incentives to be less territorial and by increasing cross-team trust. We know the science of global warming. Last winter sucked. This summer we’re going to be huffing smoke and watching our forests turn to ash.

• How do we change population habits, economies that are unfavorable to renewables, public values, and political will?
• How do you get people to adopt AI?
• How do we build trust and communication plus accountability norms to support remote work?
• How do we increase psychological safety and reduce burnout? (I have entire articles on this by the way, this is a semi-rhetorical question).

Ergo Adaptive Leadership.

We mobilize people to face difficult, changing problems that do not have a clear technical fix. We use it when the challenge requires learning, behavior change, conflict navigation, or helping people adjust to new realities rather than just applying existing expertise. It is especially useful for uncertainty, institutional change, competing stakeholder demands, and situations where the old playbook has started smoking and smoldering in our hands.

(Ronald, 1998 in Mobilizing Adaptive Work: Beyond Visionary Leadership)

Adaptive Leadership is the most relevant overall because modern life keeps handing people problems with no clean manual: disruption, ambiguity, shifting roles, and unstable conditions.

We are leading through turbulence.

Adaptive leadership is how we solve the big sticky problems. It is and will be how we innovate past our preconceived notions to disrupt the status quo. Adaptive is fun. It’s abstract, philosophical, and about evolving teams beyond what they are into something new that’s capable of solving the previously impossible.

Curious on how to implement Adaptive Leadership and to learn more? I have two options for you:

1. Subscribe and you’ll be the first to know when my guide comes out.
2. Do what I’m doing and go read all the primary sources and scientific literature.

The research is going to happen either way. But why do your own homework when I can do it for you? That wouldn’t be a smart use of your time. Just subscribe and go do something else that’s productive. You’re a leader. It’s called delegation. Delegate for once. Trust me. I got this. If you subscribe I’ll deliver the post right to your inbox. You literally cannot mess this up.

I believe in you.

2. Inclusive Leadership

In the 1980s and 90s, organizations began formally grappling with workforce diversity through compliance-driven diversity programs. The conversation was largely focused on “Managing Diversity” and the goal outcomes were often optics-based and performative. Diversity was about who is present. Not, who is influencing decisions.

The early 2000s strike different chords as research draws a distinction between diversity (composition) and inclusion (experience). Edmondson’s 1999 work on psychological safety enters the scene and establishes that people contribute more when they feel safe.

(Amy Edmondson. Source: The Nordic Business Form 2022)

Over the next decade, conversations evolve from

“Do we have diverse people?” to “Do all people participate and matter?”

Inclusion becomes a distinct concept and is strongly linked to voice, safety, and engagement. 2010 is where I date the foundation of Inclusive leadership with Carmeli, Reiter-Palmon, and Ziv’s work which asserts that leaders who are open, accessible, and available increase psychological safety, which increases creativity. Through this lens, inclusivity becomes a leadership behavior, not just an organizational goal.

Inclusive leadership is the ability to design conditions where different voices show up, speak up, and matter. Inclusive leadership is about gardening an environment where people feel valued, safe to contribute, and able to influence outcomes.

Modern teams are more diverse across background, identity, expertise, geography, and communication style than ever. Inclusive leadership matters because the ability to create belonging, psychological safety, and real participation is now central to whether groups function at all.

(Source: Bart Reijven, 2020)

Here’s some examples to break it down.

Non-inclusive version:

1. 2 senior people dominate
2. Others nod, say little
3. Decision is fast but shallow

Inclusive version:

1. Leader pauses and asks quieter members for input
2. Someone raises a concern that changes the direction
3. Discussion is messier but outcome is stronger

Same team. Different leadership. And an entirely different result.

Inclusive leadership booms through the 10s and into the 2020s and it becomes a central force for Diversity, Equity, and Inclusion initiatives, innovation and team performance, and global cross-cultural leadership.

A modern example would be Deloitte’s 6 Cs model of inclusive leadership:

1. Commitment
2. Courage
3. Cognizance of bias
4. Curiosity
5. Cultural intelligence
6. Collaboration

(Source: Deloitte University Press, 2019)

Inclusive leadership is extremely relevant because the growing problem that people are physically in the room but psychologically absent. Inclusive leadership is all about making sure the intelligence in the room actually gets into the room.

3. Coaching Leadership

Before the “coaching leadership” style formally existed, the core ideas were already alive in psychology.

1. Carl Rogers (1951), person-centered therapy.
   1. Carl emphasized listening, empathy, and helping people find their own answers.
2. Adult learning theory (Knowles, 1970s).
   1. Knowles asserts adults learn best when they are self-directed, not instructed.

(Source: Ted Lasso, Apple TV 2023)

You ever known someone who has addictive tendencies or makes chronic poor relationship choices? (besides me – pick someone other than me)

Psychology, of course, has explanations for this.

Researchers in the early 70s converged on the knowledge that people don’t grow because they’re told what to do. They grow when they reflect, explore, and take ownership. And reflecting, exploring, and taking ownership is not an inherently fun thing to do! So we usually don’t. This is why our best friend’s last three ex’s are all mentally unstable and have intoxicating and harmful behaviors.

These adult learning and development theories developing were not directly about leadership, yet. This changes in the late 70s and early 80s as “coaching” enters the world of performance and personal development.

One of the biggest sources here is Timothy Gallwey (1974), The Inner Game of Tennis. Tim argues that performance is limited more by internal interference than lack of instruction and coaching unlocks potential, it doesn’t give answers.

Huge shift here folks – lock-in with me- : coaching is about helping people think, not telling them what to do. 🤯

• Whitmore’s (1992), Coaching for Performance popularized coaching in business and introduced the GROW model (Goal, Reality, Options, Will).
• Ellinger and Bostrom (1999) studied managers as coaches in learning organizations and identified behaviors like asking questions, facilitating learning, and encouraging reflection.
• Ellinger, Ellinger, and Keller (2003) connected coaching behaviors to performance outcomes.
• Emotional Intelligence (Goleman, 2000) identified the “coaching style” as one of six leadership styles.

From these works, leadership development programs start emphasizing feedback, mentoring, and developmental conversations.

(Source: Athena Training and Consulting Inc. 2021)

Today, coaching leadership is everywhere, especially in knowledge work areas where the main tool isn’t hands or PCs, it’s the brain.

• Factory work —> you produce physical goods
• Knowledge work —> you produce ideas, decisions, solutions, insights
  • Tech and digital innovation environments
  • Hands-on research and development of physical products

AI bulls will say Knowledge work is disappearing due to the rise of AI.

I say… maybe! We’ll see, won’t we? If that’s true then the demand for emotionally intelligent leaders who can coach the people running the AIs will grow. AI bears still draw the conclusion that AI is overvalued since most people are getting AI value at a steep discount due to the entire industry being funded by venture capital not revenue. Anyways, back to coaching leadership…

A lot of people no longer respond well to command-and-control leadership, especially in knowledge work. Talent development, succession planning, and any environment where people need to become stronger thinkers demands lending autonomy and room to develop critical thinking. Coaching people up is not about growing better rule-followers.

(Source: Julia Vastrik, LinkedIn 2025)

Curious on how to adopt a coaching leadership style?

Man! – I’m really proud of you for being curious.

As your coach let’s define the goal outcome. You need:

• actionable leadership advice towards building leadership skills
• accessible roadmaps for building emotional intelligence
• all tools and dialogue to be science-based with primary source references

4. Digital / Virtual Leadership

E-Leadership was coined in 2002 by Avolio & Kahai as

“leadership mediated by information technology, where influence happens through digital channels rather than face-to-face interaction.”

It’s important to note here that leadership didn’t change but the medium of influence did.

(Source: Ideas.Ted.Com, 2020)

And along with the medium of influence brings questions about operating in a new digital frontier!

1. How do we build trust without a physical presence?
2. How does communication richness affect leadership?
3. Can technology substitute for leadership behaviors?
4. What kinds of leadership actions work when teams aren’t co-located?

These questions smolder and develop around the phenomenon of virtual teaming.

Most of us in-person scrubs (that’s me btw) were oblivious to the remote world and the gains it made during the 21st century leading up to our mass indoctrination in 2019.

The COVID-19 pandemic was gas lovingly and indiscriminately poured on the fires of digital leadership studies.

From the bonfire we got the following nuggets of knowledge:

Communication is architecture.

• Good digital leaders have clear written expectations, documented decisions, and intentional meeting structures.

Micromanagement becomes harder.

• Trust replaces visibility. You can’t see productivity anymore. You have to focus on outcomes. Autonomy is given by default.
• As an aside, I had a friend working in the space sector whose boss made him and his team all constantly screen share their monitors while on shift.🤢🤮

Asynchronous thinking.

• The best digital teams don’t depend on real-time at all. Strong digital leaders write clearly enough that meetings aren’t needed. Timezones and deep work are respected. Asynchronicity reduces “meeting gravity.”

Culture must be engineered.

• In physical spaces culture spreads by osmosis. Online, it isn’t there until you build it intentionally. We use rituals (weekly demos), tone (how people write, do feedback, etc.), and psychological safety in text, not just voice.

Tech fluency.

• Choosing the right tools, avoiding software bloat and redundancy, and understanding how tools shape behavior.

A dominant share of modern leadership now happens through screens, platforms, chat, email, dashboards, and remote or hybrid coordination.

(Source: Indeed, 2021)

This matters because leading without physical presence is no longer a niche problem, it is a standard operating norm.

Digital Leadership is very interesting to me because all of a sudden, where we’re from, what we look like, and how we come-off all becomes secondary to our output. Code switching is less necessary in virtual settings. we have more time to emotionally regulate because there are built-in pauses in digital communication that aren’t there face-to-face. Remote work can be a force for equality and more emotionally intelligent outcomes as teams move to virtual platforms.

In the digital age, you need clear instructions and actionable knowledge synthesized by human sources you can trust.

If you’re finding my articles valuable, subscribe so you can cut through the static and supercharge your leadership development.

If you think my Substack is a stinky dumpster fire and I need to stop this sad attempt at writing elevated self-help… first of all you’re a true friend for enduring my work and making it 4 examples deep into this post. You may as well just subscribe.

Second of all… I would really appreciate some honest feedback. Put it in the comments if you’re feeling brave. Shoot me a DM if you want to be constructive and courteous. Restack this article with your feedback publicly if you woke up and chose violence today.

You can’t hurt me.

Lack of feedback from such a loyal reader and friend is pretty hurtful though… Now is a great time to flex those digital leadership muscles and practice giving clear, concise feedback! Good luck.

I promise I’ll be defensive and reactive at first. Then, I’ll admit you’re right and implement the feedback accordingly. If I had a moment of weakness and lashed out to protect my ego you can also expect a heartfelt and timely apology preceding my summary of how I implemented your feedback.

It’s called digital leadership, look it up.

5. Authentic Leadership

Authentic leadership is simultaneously one of my favorites and least-favorites. It’s important to mention in this big 5 because it’s everywhere. And many people get it wrong and misrepresent authentic leadership making it sound really sexy and overly effective. Like one simple pill that gives you a tone booty and an instant 6-pack. No crunches or Bulgarian split-squats required.

6-pack abs and authentic leadership are the same in that you can’t magically shortcut the hard work and discipline. The self work required to achieve authentic leadership (yes it happens to you) is a long term endeavor of learning yourself. For me, this happened over 6 years of near-weekly counseling and therapy. It may happen faster for others.

What I’m getting at, perhaps circuitously, is that we, the people who care about leadership studies and the growth of leaders in the world, need to have an honest conversation about how we portray authentic leadership and its benefits in life and the workplace.

Let’s zoom out for a minute.

By the late 20th century, leadership research had become a tad mechanical: traits, behaviors, and contingencies.

All of these were useful, but emotionally thin. At the same time, we saw major corporate scandals and had broad loss of trust in major institutions.

We still have this today in many ways. It never left just changed forms over the years.

Bigger Company (think ~Comcast, Black Rock, Palantir~) = Less Trust.

Ol’ mom and pop shop (your local espresso and avocado toast dealer) = Bigly Trust.

Researchers started asking “what makes a leader real, not just effective?”

People are increasingly skeptical of polished-but-hollow authority.

Enter Bill George, 2003, who publishes a book called Authentic Leadership based on reviews with a laundry list of executives. His core claim is that great leaders are not defined by style, but by self-awareness and values-based action. He emphasized that a leader needs purpose, values, relationships, and consistency.

(Source: Sharon Gill, LinkedIn 2023)

Avolio, Luthans, and Walumbwa in the mid-2000s defined Authentic leadership as having four key components:

1. Self-awareness
2. Relational transparency
3. Balanced processing (considering multiple viewpoints)
4. Internalized moral perspective

It intersects with transformational and ethical leadership as well as positive organizational behavior, so much so that it can be hard to draw distinct lines between the theories. At its heart, authentic leadership argues that leadership is not a performance you put on; it’s a pattern of alignment between who you are, what you value, and how you act.

Some literature has strong evidence to support Authentic Leadership styles as an answer to psychological safety, burnout, and finding work meaningful. Authentic leadership still matters because people want leaders who seem real, consistent, and grounded rather than purely performative.

(Source: Avolio et.al., 2004)

We’re hyper-sensitive to people performing authenticity to grift us of our attention, time, and money.

Authenticity has been commodified and monetized to the point where it’s hard to know and find trust in those online and around us. When we find someone who comes across as authentic to us, it’s a breath of fresh air.

With that, authenticity ask us to show up and be radically transparent. Which can be dangerous and harmful for some.

My close friend identifies as queer and is atheist due to being subjugated to a religious cult as a kid. She attends university to become a teacher and her cohort is deeply Catholic. There is nothing inherently wrong with being religious, by the way.

During group discussions, it has been claimed by self proclaimed students that “teachers shouldn’t talk about their gay relationships in front of kids” and “being gay is wrong and shouldn’t be acknowledged in schools because it is against the lord and not in line with proper values.”

As a staunch and outspoken advocate for the rights of all people, my friend tried to speak out against her cohort but was picked on and alienated by the class. Authenticity is easy to say and easy to type.

(Source, Istock photos, 2026)

And I respectfully call bullshit.

Being radically transparent only works when [who you really are] is already in line with the local dominant leadership archetypes.

1. e.g. My friend can be authentic in a group of like-minded and accepting colleagues.
2. e.g. It is socially punishing to be authentic in a classroom with people of different beliefs who use those beliefs to extrapolate what is and is not okay for others.

(Source, @midtownunifom, 2022)

Radical Authentic leadership supporters tell us that by being ourselves we’re morally better-than. It inflates our sense of justice and perceived right-ness. That by merely calling ourselves authentic and saying “I embrace my true self” you become a leader worth admiring. That you instantly become a leader worth following who is helpful through sheer virtue of being yourself. This is borderline narcissistic and deeply wrong.

Think about the charismatic cult leader. Authenticity is great until we weaponize it for the benefit of organizational goals and capitalistic objectives.

I find authentic leadership interesting because at its core its asking for self-acknowledgement self-regulation and development of a balanced perspective.

I believe real authentic leadership is very punk rock.

• It’s knowing what’s right. It’s doing the right thing even when the right thing is unpopular. It’s standing up to bullies. It’s dissenting in a board room of people older than you.

We all could regulate more, consider multiple viewpoints, and find ways of being empathetically transparent. And, through this self-work we will no doubt be more useful and ready to serve. Think critically while reading notes on Substack like “alignment is clarity” and “embrace your true self and never lose clarity again.”

So, Authentic leadership makes the top 5 for three reasons:

1. It has gained considerable popularity and is supported by a growing body of empirical research; however, its evidentiary base is arguably overstated. For my finance bros, it’s trading at a premium, in a speculative bubble, and lacking sufficient underlying support in robust empirical outcomes.
2. The principles it stands for are solutions to problems we’re facing. Self-awareness is critical, transparency builds trust, and considering multiple views leads to better engagement and higher quality decisions.
3. It undermines the credibility of the leadership field by conferring an unearned moral authority upon already privileged individuals.

I could go all day. To my managers and aspiring leaders out there: be weary of the organization asking you to be authentic as a tool to meet their outcomes. Authenticity is earned, not performed. And it certainly isn’t a tool to increase performance. To my new people entering the workforce: know what you care about, trust your gut, focus on helping others, and learn to set boundaries.

Key Takeaways

There are a large number of leadership theories available. All of them are interesting, and the ones we should pay the most attention to are those that help us live in the increasingly digital world, build the best teams, and solve the biggest problems. Prevalent leadership theories that are solid in principle can overextend our standing. Be aware of the theories and practices we embody and teach. In Pt.IV, I think I’ll do a review of the toolkit and share the most common scenarios one may need a leadership style and the best ones for the job.

The most important step is always the next one.

Summary

Modern leadership theory emphasizes flexible leadership styles, adaptive management, and situational leadership rather than relying on a single approach. Effective leaders balance transactional and transformational leadership while applying the right tools to the right context, recognizing that complex organizational challenges often require behavior change, innovation, and strategic problem-solving rather than simple technical fixes. Among the most relevant approaches today, adaptive leadership stands out for navigating uncertainty, organizational change, and high-stakes decision-making, while inclusive leadership drives employee engagement, psychological safety, diversity and inclusion (DEI), and team performance by ensuring all voices contribute to outcomes.

In parallel, coaching leadership supports employee development, performance management, and leadership development by fostering critical thinking and autonomy, especially in knowledge-based industries. The rise of digital and virtual leadership reflects the shift toward remote work, hybrid teams, and technology-driven communication, where trust, clarity, and asynchronous collaboration are essential. Finally, authentic leadership highlights the importance of self-awareness, emotional intelligence, and values-based leadership, though it must be applied thoughtfully to avoid performative or inequitable outcomes. Together, these top leadership styles form a modern leadership toolkit designed to improve organizational effectiveness, team collaboration, and long-term business success.
