Current State of Scientific Research

• Global scientist population at all-time high
• R&D workforce fraction increased from 1 in 1,000 to 1.5 in 1,000 over past 20 years
• Germany: >5 in 1,000 people work in R&D (above global average)
• Annual output: >5 million scientific articles, 3.5 million patents
• More scientists producing more papers than ever before

ETH Zurich Research Productivity Study (2020)

• Methodology: counted "top researchers" (major field contributors) during active research years
• Avoided counting discoveries directly - focused on researcher identification
• Normalized top researchers by total researcher population
• Key finding: research productivity steeply decreased since 1960s-70s
• Interpretation: fewer scientists contributing to key discoveries relative to total population

Supporting Evidence for Decline

• Patrick Kazon & Michael N findings: Nobel prizes increasingly awarded for older work
• Historical pattern: prizes used to recognize recent discoveries

Nature Paper Analysis (Previous Year)

• Examined 45 million papers (back to 1945) + 3.9 million patents
• Measured "disruptive" breakthroughs via citation patterns
• Metric: whether new work made earlier citations redundant
• Results: clear evidence of declining disruptiveness across all areas
  • Physical sciences, chemistry, computer science, biomedicine affected
  • Even top journals (Nature, Science) showed decline
• Conclusion: fundamental shift from breakthrough discoveries to detail work

Recent Rebuttal Paper

• Press release claimed "research has lost none of its innovative drive"
• Identified methodological error in Nature paper
  • Excluded pre-1976 patent citations
  • Made 1970s-80s patents appear artificially groundbreaking
• Correction results:
  • Patent disruptiveness decline persists (reduced magnitude)
  • Paper disruptiveness decline unchanged
  • Overall conclusion remains: scientific progress declining

Three Hypotheses for Decline

1. Denial hypothesis: no problem exists, everything fine
2. Exhaustion hypothesis: nothing left to discover (fatal disease)
3. Systemic hypothesis: current research organization impedes progress
   • Rewards productivity over usefulness
   • Structural problems in scientific incentives
