Prioritizing a candidate's skills ('capacity') over their fit with the team ('chemistry') is a mistake. To scale culture successfully, focus on hiring people who will get along with their colleagues. The ability to collaborate and integrate is more critical for long-term success than a perfect resume.

When hiring for multiple roles at once, evaluators naturally consider the diversity of the group as a whole. This 'set' mindset encourages a mix of backgrounds and skills. In contrast, hiring one-off candidates leads to focusing on individual fit without considering the broader team composition, often reducing diversity.

Mothership's founder didn't intentionally seek an all-female leadership team. She hired for essential traits needed to build a paradigm-shifting company: resilience, optimism, imagination, curiosity, and grit. The candidates who best embodied these characteristics happened to be women, resulting in an effective and organically diverse team.

Hiring for "cultural fit" can lead to homogenous teams and groupthink. Instead, leaders should seek a "cultural complement"—candidates who align with core values but bring different perspectives and experiences, creating a richer and more innovative team alchemy.

A McKinsey study proved that the most ethnically diverse management teams deliver 35% higher financial returns. This isn't just an ethical imperative; it's a business strategy. Diverse teams offer wider cultural insights and are more willing to challenge internal blind spots, leading to smarter, more profitable decisions.

Across three billion years and four stages of mind (molecule, neuron, network, community), intelligence has consistently advanced by diversifying its thinking elements. The most powerful minds at each stage are those with the greatest variety of components. This frames diversity as a fundamental, time-tested strategy for improving competence in any system, including organizations.

Instead of hiring designers with similar profiles for easier staffing, intentionally seek out diverse skill sets that fill existing gaps. This leads to more interesting collaboration, broader capabilities, and mutual respect within the team.

Resolution Therapeutics' CEO builds his team with leaders from varied backgrounds across different diseases and drug modalities. He believes this diversity creates more robust problem-solving, as challenges that are novel in one area may have been solved in another, enabling faster and more informed decisions.

By adding resilience as a core hiring criterion, Pinterest naturally attracts diverse candidates from non-traditional backgrounds who have overcome adversity. This focus shifts hiring away from traditional signals of success, increasing diversity and bringing in employees who are better equipped for business challenges.
