What we know matters. But what we know others know can make or break a deal. Professor Steven Pinker joins host Brett Hendrie to talk about common knowledge — what everyone knows that everyone knows, why it’s crucial to business and negotiation, and how shared understanding helps people get work done.

Show notes:

[0:00] Brett Hendrie on moments of shared understanding

[0:58] Meet Harvard professor Steven Pinker, who joins the episode to talk about his new book When Everyone Knows That Everyone Knows.

[2:28] What is common knowledge?

[3:49] Steven was drawn to the topic because so much of language is what we don’t say… and he began to wonder why we don’t say it.

[4:20] “Netflix and chill” is the perfect example of common knowledge in practice.

[5:33] How common knowledge can shape advertising and marketing

[7:59] It can also influence markets — think speculative bubbles, bank runs and trust in financial institutions.

[11:01] Negotiations are often only successful because of common knowledge.

[14:57] Complete openness and transparency can backfire — see Bridgewater Associates — and this is where things left unsaid (but still understood) can fill the gaps.

[18:01] What do we lose with less common knowledge in a remote or hybrid work environment? Those physical social cues — blushing, glaring, staring — communicate a lot in the end.

[19:51] In a world of information bubbles, common knowledge is getting fractured.

[21:09] What’s left unsaid has lots of value. “I think the genteel hypocrisy and innuendo and euphemism makes social life possible — but that sometimes gets in the way of actually transacting the business of life. And that balance is, I think, what we call tact, savoir faire, social skill — not being too far along one end of the spectrum. And what I think a lot of that consists of is knowing what to put in common knowledge and what to keep out of common knowledge.”

We’ve all been told to “trust our gut.” But how do you know when intuition is steering you right — or leading you astray? In this episode, host Brett Hendrie explores the science and strategy behind gut feelings with Laura Huang, professor of management and organizational development at Northeastern University. She explains why our gut is always right, how we can train ourselves to listen to what it’s telling us, and how to turn that intuiting process into a real decision-making tool — not just a hunch.

[0:00] Brett Hendrie reflects on what it means to really listen to your gut.

[1:19] Meet Laura Huang, professor of management and organizational development at Northeastern University, and author of You Already Know: The Science of Mastering Your Intuition.

[2:15] What is our gut instinct and how does it differ from intuition?

[5:03] Why is it important to disentangle our intuition from our emotions? (Hint: give yourself time.)

[6:59] There are four types of decisions we need to make — simple, complicated, complex and chaotic — and we should really only use our gut for the latter two.

[9:24] Your gut never lies. It’s 100% accurate. Why? Because it’s more like a compass than a right/wrong switch.

[11:34] Our gut and intuiting process — like most things in life — aren’t linear. They pull data points from across our lives.

[13:12] The three types of gut reactions: Eureka, Aha and Uh-Ohs.

[15:55] To train yourself to trust your gut, start by identifying what type of reaction you’re having. (What is your body actually telling you?)

[16:19] Training tip: Consider the rule of three (meet someone in three different settings) to test your gut.

[19:09] Become an “expert novice.” Think brushing your teeth with your non-dominant hand. Try that, but with a job task.

[21:39] What’s collective intuition?

[22:02] Your gut is like a whisper trying to break through the noise around you. “And so we kind of shove that aside, and the more we shove that aside, the more the whispers are buried in this sea of screams, and so I would say, listen to what whispers and not what screams. And the more we do that, the more we'll be able to master our intuition.”

In a world that never stops asking for more, how can we focus on what truly matters? In the season premiere of Visiting Experts, Brett Hendrie sits down with Oliver Burkeman, author of Meditations for Mortals and 4,000 Weeks: Time Management for Mortals, to explore the power of accepting our limits.

Oliver shares insights on why striving for perfection can hold us back, how embracing imperfection can unlock ambition, and why small, deliberate actions often lead to the biggest impact. From navigating work and life like a kayak on a river to tackling intimidating tasks “one step at a time,” this conversation offers practical strategies for reclaiming control, reducing stress, and making time for what counts.

[0:00] Brett Hendrie reflects on the myth of “zero inbox”

[1:26] Meet Oliver Burkeman, author of 4,000 Weeks: Time Management for Mortals and Meditations for Mortals, expert on productivity, time management and personal effectiveness.

[3:39] Understanding what it means to be a finite human in an infinite world, and how embracing your human limits can be freeing.

[5:52] The dangers of perfectionism in professional and personal life, and why imperfectionism can boost efficiency.

[7:19] Making conscious trade-offs instead of trying to do everything: practical tips for prioritization and decision-making.

[9:10] Oliver’s “kayak vs. superyacht” analogy for navigating uncertainty and making meaningful progress in life and work.

[10:37] Long-term, detailed plans for change can be destined for failure. Instead, start small: take action today without trying to control every outcome.

[12:21] The “just going to the shed” concept: confronting tasks and projects you’ve been avoiding to reduce decision paralysis and procrastination.

[14:43] The liberating idea: every choice on how you spend your time has a cost, and once you accept that reality, you’re free to choose which set of costs you’re willing to pay.

[16:42] Integrating imperfectionism with realistic ambition to achieve more without burnout.

[19:14] Applying these ideas as a leader or manager: balancing control and autonomy to empower teams and increase organizational productivity.

[21:18] “Obviously, what people want is like the three practices you can do every day, and then you've got this nailed. But a big part of what I'm trying to say in this book is life doesn't work like that. And so, if you actually want the change, I think you do need to work on developing the patience to sort of try these things bit by bit.

“If you were to ask me for like, what's one thing that people can do, then my answer would be: there is something in your work or your life that you know is really meaningful to you… Do 10 minutes of that thing today and actually do it.”

Every search, like, and click leaves a trace — but what do these digital breadcrumbs really say about you? Author and professor Sandra Matz joined host Brett Hendrie to explore the psychology of data and how businesses use this information to build detailed profiles, predicting everything from your personality to your spending habits. How much do they really know, and what can you do about it?

Three takeaways

1. What you do online says so much more about you than you realize. Even the words you use in social posts can be telling about your personality. If you use lots of self-centred language (I, me, myself), it can actually be a sign of emotional distress. And studies from nearly a decade ago show that by simply analyzing a person's Facebook likes and follows, AI can be better at predicting someone's personality than their closest friends and family.
2. And businesses can use this information to influence their consumer behaviour. Matz worked on one study with a beauty retailer that proves the point. For outgoing extroverts, language on the ads highlighted the fun nights ahead, while for introverts the ads focused on self-care at home, and the campaign was hugely successful. But Matz warns, leaders need to be very cautious about using this type of information; after all trust is easily broken and it's a fine line between giving people exactly what they want and need from a company and manipulation.
3. Finally, when it comes to privacy issues, Matz warns it's not your social posts people should be most concerned with. It's our phones. The apps on our phones often have complete access to our photo galleries, location data, and even message history. Managing your data privacy can be a full-time job, but for folks who want to take a first step, she recommends being way more mindful about the permissions you give to companies when downloading your next app or game.

Is inclusion the secret to high-performing teams? In this episode of Rotman Visiting Experts, Brett Hendrie sits down with Anne Chow, former CEO of AT&T Business and author of Lead Bigger, to explore why true inclusion goes beyond DEI—and why leaders who embrace it outperform those who don’t. From creating psychologically safe workplaces to rethinking flexibility and performance metrics, Chow shares practical insights on how leaders can cultivate cultures where employees — and businesses — thrive.

Three takeaways

• Inclusion has been stuck on the end of the DEI acronym. To Chow, inclusion is more than just representation. It's broadening our perspectives and ensuring the voices of all our stakeholders — from employees to regulators to unions to media to customers — are heard and considered. The world is changing, and the better leader will be one with a diverse perspective.
• Inclusive leadership starts with caring about your employees. Chow reminds bosses that people don't have a work life and a personal life. They have one life, and it happens to consist of both work and personal obligations. "You as a leader, you have the relationship with the person based on the professional dimensions of their life, but it is incumbent upon you to respect the boundaries and the priorities of their personal life," she says. "And what that means for you as the inclusive leader is that you must put in place performance measures, accountability, clarity, as well as benefits and support structures that enable people to live a meaningful life that has professional and personal goals and contributions." And right now, the key for most leaders will be around flexibility.
• A good manager or leader will help employees thrive in their job. Team members will never lack understanding of where they are in their job, how they're doing in relation to their peers. They will know what skills they need to advance and feel their leader has provided them the resources they need to succeed. A great manager will help their people thrive in their careers, never forgetting that their current job is just one small part of the entirety of their work life. "They recognize and seek in you a potential that goes beyond your current job," she says.

The world feels more divided than ever, with anger permeating every level of society. For leaders, this creates challenges that range from difficult to seemingly impossible. How can they manage anger among employees, stakeholders, and external pressures? In the latest episode of Rotman Visiting Experts, Professor Karthik Ramanna discusses his new book, The Age of Outrage: How to Lead in a Polarizing World, and shares a practical framework for navigating these turbulent times.

Three takeaways

1. We're living in a very stressful time. Technological changes, like the advent of AI; societal shifts, such as an aging demographic; and a loss of trust in public institutions make us all a bit more...well, angry. The first thing leaders need to accept is that it's not one issue that's creating the conditions for the "age" of outrage; it's many. And if we can accept that we're living through a more polarizing time in society, we can start to address these issues more head-on.
2. Perhaps it's time those stereotypical "a-type" leaders — replete with courage, justice and wisdom — take a back seat to an oft-neglected virtue: temperance. Moderation might be key as we navigate these trying times, and Ramanna reminds listeners that some of the most influential and impactful leaders of our time have been temperate ones. Let your people - your team, your stakeholders, your customers - come to you with the right solutions; listen and trust that the processes you've put in place will help the right course of action bubble from the bottom up.
3. Leaders have limitations. You will always a) be seen as part of the problem by at least some of your stakeholders, and b) you can't solve every issue that comes across your desk. According to Ramanna, if you are clear about what issues you can own — that is identify, and offer up solutions for — then you can better manage the challenge of knowing that you can't fix everything. It's really about being authentic to your organization's values. Don't promise to solve climate change if you're an oil company; and if you can't stand behind your diversity, equity and inclusion efforts in the face of pushback, perhaps don't trumpet them to begin with.

How do small, targeted actions create massive ripple effects in business and society? Malcolm Gladwell joined host Brett Hendrie to discuss his latest book, Revenge of the Tipping Point, unpacking the hidden forces behind epidemics, the power of overlooked metrics, and the stories that shape our world.

Head over to our YouTube channel to watch this conversation as well!

Three takeaways

1. Epidemics, be they health or societal, are often started by a very, very small number of individuals. Gladwell points to the opioid epidemic in the U.S. While it's had a massive impact on hundreds and thousands across the U.S. (and beyond), the root of the crisis owes its thanks to Purdue Pharma, which relentlessly targeted just a small handful of doctors. By micro-targeting a handful of physicians willing to over-prescribe painkillers, Purdue engineered a national crisis.
2. We're often shaped by narratives in ways we aren't always aware of, and they tend to be more community and locally based than we realize. Gladwell uses the concept of "overstories," that is how the upper canopy of a forest shapes life below it, to explore how these stories — say Canada's pride in multicultralism and immigration — can shape entire nations. As we become increasingly digitized and decentralized in our community identities, it's worth considering which new "overstories" are shaping how we interact with the world.
3. The law of a few — that epidemics are shaped by just a few individuals, often with unique gifts — was one of Gladwell's most enduring concepts introduced in The Tipping Point. This time around, he introduces us to the idea of "the rule of thirds." You don't need a majority or even an even split to achieve critical mass, particularly with positive societal change. Instead, looking at the niche example of women in male-dominated fields, critical mass might simply be "too many to ignore."
