Chris Kuenne, entrepreneurship lecturer at Princeton, and John Danner, senior fellow at the Lester Center for Entrepreneurship at UC Berkeley’s Haas School of Business talk about one of the least understood factors that leads to success at scale: the personality of the company founder. Their research describes four distinct types of highly successful entrepreneurial personalities: the Driver, the Explorer, the Crusader, and the Captain. While popular culture currently celebrates big-ego personalities in the mold of Steve Jobs, the interview guests show how different kinds of people succeed at that level. Kuenne and Danner are co-authors of the new book, “Built for Growth: How Builder Personality Shapes Your Business, Your Team, and Your Ability to Win.”

Kabir Sehgal, a corporate strategist, Grammy-winning producer, investment banker, bestselling author, and military reserve officer, talks about building and thriving in a portfolio career. He discusses the benefits of pursuing diverse interests, the tradeoffs and productivity discipline demanded by that career choice, and he offers tips for managing a schedule with multiple work activities. And he argues we should stop calling these second careers "side hustles." Sehgal is the author of the HBR article, “Why You Should Have (at Least) Two Careers.”

Dominic Barton, the global managing partner of McKinsey&Company, discusses the firm’s sustainability efforts. He talks about the wake-up call he got about sustainability and how he tries to convince CEOs hesitant to make it part of their business model that doing so will improve company performance. He says he sees companies thinking about the environment. “But the speed and scale of what we need to do — I don’t think it’s sufficient.”

Professors Michael Toffel, of Harvard Business School, and Aaron Chatterji, of Duke’s Fuqua School of Business, discuss the emerging phenomenon of CEO activism. They explain how political polarization in the U.S. and employee expectations around company values are pushing corporate leaders to enter into controversial political and social debates. Toffel and Chatterji are the coauthors of the HBR article “Divided We Lead.” We also hear from PayPal CEO Dan Schulman, who talks about standing up for transgender rights and what he tells other CEOs who ask his advice on taking on an activist role.

Jennifer Petriglieri, an assistant professor of organizational behavior at INSEAD, asks company leaders to consider whether they really need to relocate their high-potential employees or make them travel so much. She says moving around is particularly hard on dual-career couples. And if workers can't set boundaries around mobility and flexibility, she argues, firms lose out on talent. Petriglieri is the author of the HBR article “Talent Management and the Dual-Career Couple.”

Tasha Eurich, an organizational psychologist and executive coach, talks about why we all should be working on self-awareness. Few people are truly self-aware, she says, and those who are don’t get there through introspection. She explains how to develop self-awareness through the feedback of loving critics and how to mentor someone who isn’t self-aware. Eurich is the author of the book “Insight.”

Kieran Setiya, a philosophy professor at MIT, says many people experience a mid-career crisis. Some have regrets about paths not taken or serious professional missteps; others feel a sense of boredom or futility in their ongoing streams of work. The answer isn't always to find a new job or lobby for a promotion. Motivated by his own crisis, Setiya started looking for ways to cope and discovered several strategies that can help all of us shift our perspective on our careers and get out of the slump without jumping ship.

Ryan Buell, associate professor at Harvard Business School, says the never-ending quest for operational efficiency is having unintended consequences. When customers don’t see the work that’s being done in back offices, offshore factories, and algorithms, they’re less satisfied with their purchases. Buell believes organizations should deliberately design windows into and out of operations. He says increasing operational transparency helps customers and employees alike appreciate the value being created. Buell is the author of the HBR article "Operational Transparency."

Tomas Chamorro-Premuzic, a psychologist and chief talent scientist at ManpowerGroup, says we're not picking leaders in the right way. While we should be promoting people based on their competence and potential, it's often the incompetent, overconfident candidates -- most of them men -- who get ahead. Studies show that, by many measures, women are actually better equipped to become strong, successful managers. But the solution to getting more of them into the executive ranks isn't quotas or other initiatives that mandate gender diversity. To improve leadership across the board, we need to focus on the metrics proven to enhance performance and set higher standards for everyone. Chamorro-Premuzic is also a professor of business psychology at University College London and Columbia University, and the author of the book "Why Do So Many Incompetent Men Become Leaders?: (And How to Fix It)" (Harvard Business Review Press, 2019).

Caitlyn Collins, a sociologist at Washington University in St. Louis, conducted interviews with mothers in four countries -- the United States, Italy, Germany, and Sweden -- who have jobs outside the home to better understand the pressures they felt. She found that American moms were by far the most stressed, primarily because of the lack of parental benefits offered by their employers and the government. In Europe, women told Collins they had more help, but at times cultural norms around their personal and professional roles had yet to catch up. Collins thinks companies can work to improve the situation but argues that the real solution is carefully designed government interventions that will help families at all income levels. She’s the author of the book “Making Motherhood Work: How Women Manage Careers and Caregiving.”

Joseph Fuller, professor at Harvard Business School, says that the story we hear about workers being afraid for the future of their jobs might not be right. In surveying 11,000 people in lower-income and middle-skills jobs and 6,500 managers across 11 countries, Fuller discovered that, contrary to what bosses believe, many employees are excited about new technologies and willing to be trained in new skills. But they don't always know what they need to learn or how to access and pay for it. Organizations can do a better job of identifying the skills gaps they have or will soon face and using their existing workforces to fill them. Fuller's project is a joint venture between the HBS Project on Managing the Future of Work and the Boston Consulting Group’s Henderson Institute. He's a co-author of the HBR article “Your Workforce is More Adaptable Than You Think."

Matt Beane, assistant professor at the University of California, Santa Barbara, finds that robots, machine learning, and AI are changing how we train for our jobs — not just how we do them. His study shows that robot-assisted surgery is disrupting the traditional learning pathway of younger physicians. He says this trend is emerging in many industries, from finance to law enforcement to education. And he shares lessons from trainees who are successfully working around these new barriers. Beane is the author of the HBR article “Learning to Work with Intelligent Machines.”

Daisy Dowling, founder and CEO of Workparent, says that moms and dads with jobs outside the home don't have to feel stressed or guilty about trying to balance their professional and personal lives. The key is to tease apart the different challenges -- from coping with feelings of loss to managing practicalities -- and to adopt strategies to better guide you through each. She points out that while a lot of emphasis is placed on parental leave, and especially new mothers, people at all stages of parenting need practical, immediate, and effective solutions they can implement themselves. Dowling is the author of the HBR article "A Working Parent’s Survival Guide."

Jennifer Petriglieri, associate professor at INSEAD, studied more than 100 couples where both partners have big professional goals. She finds that being successful in your careers and your relationship involves planning, mapping, and ongoing communication. She also identifies different models for managing dual-career relationships and explains the traps that couples typically encounter. Petriglieri is the author of the book “Couples That Work: How Dual-Career Couples Can Thrive in Love and Work.”

Scott Young, who gained fame for teaching himself the four-year MIT computer science curriculum in just 12 months, says that the type of fast, focused learning he employed is possible for all of us -- whether we want to master coding, become fluent in a foreign language, or excel at public speaking. And, in a dynamic, fast-paced business environment that leaves so many of us strapped for time and struggling to keep up, he believes that the ability to quickly develop new knowledge and skills will be a tremendous asset. After researching best practices and experimenting on his own, he has developed a set of principles that any of us can follow to become "ultralearners." Young is the author of the book "Ultralearning: Master Hard Skills, Outsmart the Competition, and Accelerate Your Career."

Ethan Bernstein, associate professor at Harvard Business School, studied how coworkers interacted before and after their company moved to an open office plan. The research shows why open workspaces often fail to foster the collaboration they’re designed for. Workers get good at shutting others out and their interactions can even decline. Bernstein explains how companies can conduct experiments to learn how to achieve the productive interactions they want. With Ben Waber of Humanyze, Bernstein wrote the HBR article "The Truth About Open Offices."

Jim McKelvey, entrepreneur and cofounder of Square, says that most companies that think of themselves as innovative are really just copycats. True innovation, he argues, is about fearlessly exploring novel solutions and dramatically expanding markets. Doing so also helps startups defend their innovations against industry giants, as Square did against Amazon. McKelvey is the author of the book “The Innovation Stack: Building an Unbeatable Business One Crazy Idea at a Time.”

Stewart Friedman, organizational psychologist at The Wharton School, and Alyssa Westring, associate professor at DePaul University’s Driehaus College of Business, say it’s a mistake for a working parent to think of career and home life as competing interests that have to be balanced. Their research shows how many leadership skills apply to parenting, and vice versa. The professors explain how individuals can stop making tradeoffs and instead find sustainable ways to advance their careers and also parent more effectively. Friedman and Westring are the authors of the book "Parents Who Lead: The Leadership Approach You Need to Parent with Purpose, Fuel Your Career, and Create a Richer Life."

A special thanks to Core77 reader Ross Oliver, who read our post on Cheat Sheets and commented that silicone--which I always thought was inert--may in fact leach harmful chemicals into food.

Oliver provided a link to Life Without Plastic, a company founded in 2006 by two parents seeking alternatives to plastic for their then-newborn child. Today the company sells over 450 products made from nontoxic alternatives to plastic, like good ol' glass and stainless steel. Because they do sell some items that feature silicone gaskets and seals, their website has a section on silicone, where they provide links to several peer-reviewed studies done on how the material reacts with food. Here's some relevant information:

Silicones are not completely inert or chemically unreactive and can release toxic chemicals. They can leach certain synthetic chemicals at low levels, and the leaching is increased with fatty substances, such as oils.

One study tested the release of siloxanes from silicone nipples and bakeware into milk, baby formula and a simulant solution of alcohol and water. Nothing was released into the milk or formula after six hours, but after 72 hours in the alcohol solution several siloxanes were detected.

Another study found siloxanes [a byproduct of the polymerization process used to create a silicone product] being released from silicone bakeware, with leaching increasing as the food fat content increased.

A review of the literature indicated that the key critical effects of common siloxanes, as shown in animal studies, are impaired fertility and potential carcinogenicity (2005 Report by the Danish Ministry of the Environment: Siloxanes - Consumption, Toxicity and Alternatives).

The European Union considers certain siloxanes to be endocrine disruptors (Study on enhancing the Endocrine Disruptor priority list with a focus on low production volume chemicals, ENV.D.4/ETU/2005/00w28r).

If you use silicone in your kitchen, I'd say the entire page is well worth a read.
