I do not have a degree. Yet, I have spent my career navigating from manual QA to software engineering, cloud architecture, and consulting.
Whenever I look at the modern tech landscape, the prevalence of “Degree Required” in job ads stands out. To be clear: completing a degree is a testament to hard work, focus, and dedication. I have immense respect for those who have done it.
But there is a difference between respecting an achievement and using it as the only valid proof of intelligence. When modern companies over-rely on formal credentials, they create a blind spot that filters out highly capable, non-traditional learners.
The Mental Model: Signaling vs. Human Capital
To understand why companies do this, it helps to look at Bryan Caplan’s 2018 book, The Case Against Education.
Caplan explores two ways to look at what education actually provides to the workforce:

- The Human Capital Model: You go to university, learn highly specific, valuable skills, and bring those exact skills to an employer.
- The Signaling Model: You go to university to prove to an employer that you possess underlying traits: you are intelligent, you can hit deadlines, and you can conform to a system.
Employers rely heavily on the signal. It is a convenient heuristic to filter hundreds of applications. But convenience comes with a cost. By relying purely on the academic signal, organisations overlook candidates who have built massive reserves of “human capital” through unconventional, practical experience.
The cost of the single filter
The modern workplace, especially an AI-assisted one, requires immense adaptability. Academic environments are fantastic for teaching theory, but they often struggle to simulate the messy, undocumented, and chaotic reality of enterprise systems.
When you prioritise academic credentials over practical experience, you risk a mismatch. You might hire someone who is brilliant at passing standardised tests, but struggle to find someone who knows how to debug a failing production environment at 2 AM.
We don’t need to lower the bar; we need to widen the lens.
The practical upshot
How can organisations actually fix this and start valuing diverse forms of learning?
- Elevate Vocational & Continuous Learning: Traditional education is a snapshot in time. Vocational training is a continuous loop. Organisations should prioritise on-the-job training that focuses on
