As researchers age, they produce less disruptive work
Claims that scientists produce less disruptive work as they age prompt debate over whether the cause is biology, career incentives, or entrenched power structures. Commenters contrast young researchers’ risk-taking and fresh perspectives with older scientists’ roles as gatekeepers, citing examples from Einstein and quantum mechanics to modern grant-driven academia. Many suggest that institutional conservatism and the shift from exploring new ideas to exploiting established ones may matter more than age itself.
Tension Between Quantum Mechanics and General Relativity
- Several comments stress that unifying QM and GR is intrinsically hard, not just an “old Einstein” problem.
- Some argue a unified theory must exist if the universe is lawful and both current theories are approximately correct, since using them together yields contradictions.
- Others note we don’t know if a “theory of everything” even exists; there’s no strong scientific basis to assume it.
- Conceptual tensions are highlighted (e.g., gravity of a particle in spatial superposition, nonlocality, collapse vs. classical fields, difficulty of quantizing gravity).
- There is debate over whether Einstein was a “gatekeeper” against QM or a key contributor whose skepticism productively exposed issues like nonlocality.
Aging, Disruption, and Scientific Practice
- Many see the shift from disruptive to conservative work as driven more by incentives and social roles than pure biology.
- Younger researchers are said to be more willing to take risks, lack strong priors on “what’s impossible,” and are still building reputations.
- Older scientists often have more to lose, more administrative and funding responsibilities, families, and less appetite for high-risk projects.
- Mental peak around 25–35 and “mental ruts” from long time in one field are mentioned; switching fields is suggested as a way to regain fresh perspectives.
- Classic “explore vs. exploit”: early career = exploration and potentially disruptive work with low pay; later = safer, better-funded work.
Gatekeeping, Institutions, and “Science by Funeral”
- The “science advances one funeral at a time” idea is both endorsed and criticized.
- Examples are given of powerful figures blocking alternative ideas for decades; others argue scientific history has many counterexamples and not all progress is a rebellion against elders.
- Institutions and grant systems are said to reward incremental, buzzword-aligned work over disruptive ideas; being in constant opposition is described as exhausting.
Technology, Generations, and Attitudes to Change
- Douglas Adams’ “three rules” about how different ages perceive new tech resonate with many, especially regarding AI, social media, and short-form video.
- Several commenters note becoming more skeptical with age, viewing new tech (crypto, AI, smartphones) through early-life values (e.g., surveillance concerns) rather than pure novelty.
- Others argue novelty itself declines; repeated hype cycles and negative side effects dampen enthusiasm for disruption.
