Leanne ten Brinke is an Associate Professor at the University of British Columbia, where she directs the Truth and Trust Lab. Her research investigates trust, deception, and dark personality traits across diverse populations—from incarcerated individuals to hedge fund managers and politicians. She reveals how dark personality traits shape our institutions and relationships, while offering practical strategies to recognize and counteract their harmful influence. Her book is titled Poisonous People: How to Resist Them and Improve Your Life (Amazon, Bookshop)*.

If you are a leader, you are going to deal with poisonous people. Sometimes they will show up as clients, sometimes your boss, sometimes your peers, and sometimes the people you manage. Regardless of where they show up, this conversation with Leanne will help you handle this tough dynamic.

• Dark traits exist on a spectrum. While only 1% of the population rises to a clinical level of psychopathology, 10-20% of the population has a dark personality profile.
• There are many more people with psychopathy per capita in senior management positions than in the general population.
• Poisonous people generally aren’t interested in shifting their personality. As such, you will not change them. Given that reality, aim to better manage the relationship.
• Establish clear boundaries with poisonous people and put things in writing you might normally assume. Dark personalities are really good at exploiting unspoken norms.
• Find ways to create win-wins with poisonous people. They don’t do well with trade-offs, because they don’t like to lose anything.
• Avoid face-to-face negotiations with them. Their charm and charisma will win you over in the moment. Text-based dialogue will help you objectively negotiate better.
• Use the carrot instead of the stick. Reward good behavior when it happens (just not by giving them power over others).

It sometimes seems like someone with a good sense of humor does everything a bit better. Perhaps leadership is no different – but it’s not about landing jokes. In this episode, Chris and I explore why everyday humor is all about paying attention and generosity.

• Humor might not make the list of top leadership competencies, but it helps you perform every other competency better.
• A good sense of humor is inherently generous.
• Effective humor isn’t landing the perfect joke or being the center of attention. It’s noticing the humor is everyday work and bravely calling attention to it.
• The first pillar of cultivating humor is simply being present.
• Start with times you are least present and most zoned out. Zero in with a “new bathroom” frame of mind.
• Celebrate the bad stuff and find humor in it. By doing so, you inherently help people appreciate excellence.

Most of us have gone through some version of a reorg. A lot of leaders have also implemented their own reorgs. Sometimes they work. Many times, they don’t. In this conversation, Phil and I discuss what goes wrong with reorgs and how we can do better.

• Organizations traditionally looked like the tin man from The Wizard of Oz: perfectly planned, many interchangeable parts, not flexible.
• An octopus organization adapts, works independently to serve the larger whole, and is innately curious.
• A reorg that starts with an org chart misses the complex organic connections you are unlikely to fully understand.
• Prioritize structural stability while building internal flexibility.
• Nurture the complex informal human networks that deliver value.
• Be honest about objectives and communicate a reorg early.
• Engage people by starting with smaller-scale change. Clarify the problem to be solved instead of the structural “answer.”
