Unlocking Career Growth: The Science Behind Diverse Skill Sets

Spread the science

In today’s rapidly changing job market, the traditional path of specializing in one area might no longer be the key to career growth and success. Huh?

A recent study leverages network-based tools (one of our favorites) from the Economic Complexity framework to provide a fresh perspective on how diverse and complex skill sets can influence wages and career mobility.

The Changing Landscape of Job Skills

The job market is evolving, driven by technological advancements and shifts in economic structures. This study explores how different occupations require specific skill sets and how these skills relate to wages. The researchers used data from O*NET, a comprehensive database that details the skills and knowledge required for various occupations. By analyzing this data through the lens of Economic Complexity, the study offers new insights into the interplay between skills, job complexity, and wages.

Building Networks: Jobs and Skills

Imagine a vast web where each node represents a job, and the links between them signify shared skills. This is the essence of the Job and Skill Progression Networks constructed in the study. These networks help identify paths for career growth and highlight the skills that frequently occur together in different jobs.

  1. Job Progression Network (JPN): This network shows how jobs are interconnected based on the skills they require. For example, if “Job A” and “Job B” both require skill sets X, Y, and Z, they are linked in the network. This linkage suggests potential career paths for individuals looking to switch jobs or advance in their careers.
  2. Skill Progression Network (SPN): Similarly, the SPN maps out how different skills are related by showing which skills frequently co-occur in various jobs. This network helps identify clusters of related skills, making it easier to understand how skill sets are bundled in the labor market.

Measuring Job Complexity and Coherence

Two key concepts introduced in the study are job complexity and skill coherence.

  • Job Complexity: This measure, termed “job fitness,” assesses how diverse and sophisticated the skill set required for a job is. High-fitness jobs require a broad range of complex skills, while low-fitness jobs need fewer, more basic skills.
  • Skill Coherence: This metric evaluates how closely related the skills required for a job are. High-coherence jobs have skill sets that frequently occur together, while low-coherence jobs require a more varied and less related set of skills.

Findings: Complexity, Coherence, and Wages

The study’s findings reveal a nuanced relationship between job complexity, skill coherence, and wages:

  • Complex Jobs and Higher Wages: Generally, jobs that require a diverse set of complex skills tend to offer higher wages. This aligns with the idea that employees with a broader skill set can contribute more significantly to an organization, thus commanding higher salaries.
  • Skill Coherence and Wage Disparities: Interestingly, jobs with lower skill coherence often offer higher wages. This suggests that workers with a mix of unrelated skills may be more adaptable and valuable in the job market, leading to better compensation. Conversely, highly coherent jobs, which rely on a tight cluster of related skills, tend to pay less.

Policy Implications and Career Advice

These findings have important implications for policymakers, job seekers, and those interested in career growth. For policymakers, the study suggests that fostering training programs that emphasize the acquisition of diverse and complex skill sets can enhance workforce mobility and wage growth. For job seekers, the research highlights the value of cultivating a broad skill set rather than focusing too narrowly on specialization.

Real-World Applications

Consider a software developer who also has strong skills in project management and communication. According to the study, this combination of diverse skills could make them more valuable and adaptable in the job market compared to a developer who only focuses on technical skills. Similarly, someone working in healthcare who also knows data analysis and patient communication may find more opportunities for career advancement and higher wages.

Hey, so let us know in the comments!

  1. How can individuals effectively acquire and integrate diverse skill sets to enhance their career prospects?
  2. What role should educational institutions play in preparing students for a job market that values diverse and complex skill sets? This question is for the teachers out there!


The evolving job market demands a new approach to career development. By understanding the complexity and coherence of skills required for different jobs, individuals can better navigate their career growth and maximize their earning potential. Policymakers and employers can also benefit from these insights by designing more effective training programs and labor market policies.
