Intelligence Volume 116, May–June 2026, 102005 Intelligence Research Paper No evidence for reversed publication bias in research on intelligence and school grades: Funnel plot asymmetry as an artifact of conditional standard errors Hynek Cígler
Highlights • No evidence of reversed publication bias in Roth et al. (2015). • Funnel plot asymmetry stems from using conditional SEs against raw correlations. • Asymmetry disappears when using Fisher z-transformed correlations. • Weights based on conditional SEs inflate the meta-analytic total effect size. • Conditional SEs of correlations should be avoided in meta-analyses. Abstract Reversed publication bias—the idea that politically sensitive findings may be selectively suppressed in favor of null effects—has recently gained attention in public and online discussions. Roth et al.'s (2015) meta-analysis of the association between intelligence and school grades (ρ = 0.54) has been frequently cited as supposed evidence, because its funnel plots appear to show larger correlations in studies with smaller sampling error. However, this study demonstrates that the pattern is entirely spurious. Reanalysis of the original data reveals that the asymmetry arises from the use of the conditional standard error of the correlation coefficient, which depends on the observed value of r and mechanically induces funnel-plot skew. When more appropriate methods, such as Fisher's z-transformation with unconditional standard errors, are applied, the asymmetry disappears and Egger's test becomes nonsignificant, t(238) = −1.41, p = .160. A complementary simulation study further confirms that conditional-error weighting can generate strong false signals of reversed publication bias and inflate total effect-size estimates even when no bias is present. Overall, these findings provide no evidence for reversed publication bias in research on intelligence and school grades. Using conditional standard errors of raw correlation coefficients in meta-analyses should be completely avoided.
Fig. 2 presents three funnel plots corresponding to models M1–M3. The reproduction of Roth et al.'s (2015) plot using conditional standard errors (panel B) was successful (compare to Fig. 1, panel A), showing clear asymmetry in which smaller studies appeared to report lower correlations. In contrast, funnel plots based on inverse sample size (panel A) or Fisher z-values with unconditional standard errors (panel C) were symmetrical, providing no visual evidence of publication bias. Fig. 2. Reproduced funnel plots. Note. Panel A (M1): Raw correlations plotted against inverse sample size; this is the approach Roth et al. (2015) used for estimating the total effect size, but not for publication bias analysis. Panel B (M2): Raw correlations plotted against approximated conditional standard errors; this reproduces the original funnel plot from Roth et al. (2015), see reproduced Fig. 1, panel A. Panel C (M3): Z-transformed correlations with their associated standard errors.
Accusations that intelligence research is shaped by “political correctness” or “ideological pressures,” potentially supported by evidence of reversed publication bias, can be used to bolster other ideologically motivated positions. The debate surrounding cross-national IQ differences (Lynn & Meisenberg, 2010; Lynn & Vanhanen, 2002) illustrates this dynamic: substantial methodological critiques (Wicherts et al., 2010) can be dismissed as politically motivated rather than evaluated on empirical and statistical grounds. Such ideological framing of intelligence research, regardless of its source, undermines objectivity and credibility of the field and should therefore be avoided.
It's commonly claimed that "controversial" or politically sensitive research is suppressed by failing to report inconvenient results. The claimed is especially common for research on the relationship between IQ & grades. A new paper shows that the core evidence for this claim is an artifact
