Context

Science is built on replication — if a finding is real, other researchers should be able to reproduce it. But when researchers tried to replicate landmark studies across psychology, medicine, and economics, the results were devastating. 50-70% of studies failed to replicate. The causes are systemic: publish-or-perish incentives, p-hacking, small sample sizes, and journals that only publish positive results. The replication crisis doesn't just affect academia — it undermines public trust in science at a time when that trust is desperately needed.

What people believe

“Published peer-reviewed research is reliable and can be trusted as the basis for decisions.”

Actual Chain
→
50-70% of landmark studies fail to replicate(Reproducibility Project: 36% of psychology studies replicated)
└
P-hacking: researchers test multiple hypotheses until one reaches p<0.05
└
Publication bias: journals only publish positive results, file drawer effect
└
Small sample sizes produce unreliable effect sizes that don't hold at scale
→
Medical treatments based on unreplicable research(Billions spent on treatments that don't work as published)
└
Drug trials that showed promise in small studies fail in large trials
└
Nutritional guidelines based on weak evidence flip-flop every decade
└
Patients receive treatments based on studies that wouldn't replicate
→
Public trust in science erodes(Trust in scientists declining, especially among certain demographics)
└
Anti-science movements cite replication failures as evidence science is unreliable
└
Legitimate scientific consensus (climate, vaccines) questioned alongside weak studies
└
Policy-makers cherry-pick studies that support their position — all have 'peer-reviewed' backing
→
Perverse incentives persist despite awareness(Academic career still depends on publication volume, not replication)
└
Replication studies are hard to publish — journals want novel findings
└
Researchers who expose non-replication face professional retaliation

Don't If

  • •You're making major decisions based on a single study, no matter how prestigious the journal
  • •You're citing research without checking if it's been replicated

If You Must

  • 1.Look for meta-analyses and systematic reviews rather than individual studies
  • 2.Check if the study has been replicated — and what the replication found
  • 3.Be skeptical of small sample sizes, surprising effect sizes, and single-study claims
  • 4.Prefer pre-registered studies where hypotheses were declared before data collection

Alternatives

  • Pre-registration — Researchers declare hypotheses and methods before collecting data — prevents p-hacking
  • Registered reports — Journals accept papers based on methodology before results are known — eliminates publication bias
  • Open science practices — Open data, open code, and pre-prints enable verification and replication
Falsifiability

This analysis is wrong if:

  • Large-scale replication projects find that 80%+ of published studies replicate successfully
  • Pre-registration and open science practices become standard without changing replication rates
  • Public trust in science remains stable despite awareness of the replication crisis
