In 1968, ecologist Garrett Hardin described a dilemma that has shaped environmental policy, economics, and social science ever since: the tragedy of the commons. When every herder rationally decides to add one more animal to the shared pasture, each one profits individually while the cost of overgrazing gets spread across everyone. Every single decision makes sense, but taken together, they destroy the resource everyone depends on. That same pattern now threatens the professional expertise of entire occupations, argues Nolan Lovett of the NATO Special Operations University in a research paper published in the journal Human Resource Development Review. His core argument goes like this: when a company replaces entry-level positions with AI, it captures 100 percent of the efficiency gains. The cost of eroding expertise, meanwhile, gets distributed across every organization that draws from the same talent pool. But experienced professionals don't appear out of thin air. They need years in entry-level roles where beginners gradually take on harder tasks, make mistakes, and learn to fix them. The causal chain of "cognitive commons" erosion: AI adoption disrupts professional development through two mechanisms, eroding deep domain expertise and undermining the ability to review AI outputs. | Image: Lovett (2026) According to Lovett, AI systems could increasingly take over exactly those tasks, and he identifies two ways this disrupts how expertise gets renewed. The first is direct elimination of entry-level positions, where AI systems handle work that used to go to junior employees. The second is more subtle: Even when entry-level jobs survive, junior workers with AI assistance hit productivity levels that used to take years of experience to reach. The cognitive effort that actually builds deep domain knowledge never happens. Without deep expertise, nobody can catch AI's mistakes This creates a follow-on problem Lovett calls the "validation tether." The ability to oversee AI systems effectively depends on exactly the kind of deep domain knowledge that AI use is wearing away. Spotting domain-specific errors in plausible-looking AI output takes more than catching obvious contradictions. Surface-level checks aren't enough to guard against serious mistakes, according to existing research. Cognitive habits make things worse. People who routinely treat AI answers as reliable lose the reflex to question them. And the training environments where junior workers once learned to challenge authority and test claims against reality are vanishing along with traditional entry-level roles. The full damage might not show up for years The experienced professionals on the job market today were trained 5 to 20 years ago. The effects of entry-level positions cut starting in 2023 may not fully show up until somewhere between 2030 and 2045, Lovett argues. He calls this the "Human Reserve Paradox." Organizations need deep expertise in reserve for validation, crisis management, and situations that overwhelm AI systems. But no single organization has enough economic incentive to maintain that reserve on its own. And even the workers who do make it through the pipeline will have shallower expertise, Lovett argues, because they spent their careers orchestrating AI rather than doing independent cognitive work. Some professions face far greater risk than others The mechanism doesn't hit every profession equally, Lovett stresses. Software engineering, financial analysis, and legal research all show high task substitutability, relatively light regulation, and strong modularity, putting them in the highest vulnerability category. Medicine and engineering get some protection from stricter regulatory requirements and stronger professional associations, but they aren't immune. The tragedy isn't inevitable, though. Lovett argues that professionals need AI-free learning environments, phased AI introduction, and a baseline of human performance that should come before AI gets involved. He recommends that professional associations test domain competence through certifications alongside AI skills, and that policymakers make training and education more attractive. Bans or restrictions on AI use aren't among his proposals. Economic evidence remains mixed A study from summer 2025 that Lovett cites at length showed employment declines in AI-affected occupations, especially among young workers. For more experienced workers in the same fields, employment held steady or even grew. The researchers attribute this to AI primarily replacing codified knowledge while practical experience stays in demand. A Federal Reserve Board study found that growth in programming jobs has nearly halved since ChatGPT launched. But a clear causal link between AI and these declines can't be proven yet. Other factors like tighter monetary policy and a correction after pandemic-era tech overhiring could also play a role. A January 2026 study found that the job crisis in AI-affected occupations actually started before ChatGPT's release. An Anthropic study from March 2026 found no measurable overall impact of AI on the labor market but did flag one warning sign: the job-finding rate in highly AI-exposed occupations dropped by half a percentage point among young workers aged 22 to 25. Studies show measurable cognitive costs from misusing AI The research on cognitive effects of too much or misguided AI use paints a much clearer picture. The findings back Lovett's argument that cognitive debt could build up over years. An MIT study using EEG measurements showed that even brief AI use weakened neural connectivity, and over 80 percent of participants struggled to recall content from their own AI-assisted writing. An Anthropic study with software developers found that participants with AI access scored 17 percent worse on knowledge tests. The biggest losses came from those who used AI purely as an answer machine. Those who used AI to get explanations learned significantly better. A Swiss study of 666 participants found a strong negative link between AI use and critical thinking, with the effect most pronounced among 17- to 25-year-olds. According to Anthropic, students themselves worry about "brain rot" because AI lets them shortcut too many learning processes. Among students in China, the pattern played out over a longer stretch. Despite homework grades improving by 18 percent, exam performance dropped by up to 24 percent, with the full effect only showing up after about two years. What matters according to the studies isn't just how much people use AI, but how they use it. Those who treat AI as a substitute for thinking lose cognitive abilities fastest, while targeted use as an explanatory tool can significantly reduce the negative effects.
