Replications
- SCORE secondary data replication of Liang et al. (2018), Parsons et al. (2025). Outcome recorded: failed.
"There were 44 coefficients on the interaction between r and age that were either insignificant (alpha = 0.05) or positive. This claim was not replicated."
Outcome read from OSF report. - Analysis, Tyner et al. (2025). Outcome recorded: successful.
""We find that the results are robust to the inclusion of the additional years of data. The relationship between the entrepreneurship level of a country and the median age of the citizens in the original study (data covering 2001 to 2010) was found to be -0.0074 (p-value 0.0000, CI: [-0.0101, -0.0047]). The relationship in the new data (2011 to 2016) is -0.0079 (p-value 0.0000, CI: [-0.010, -0.0055]). When combining the datasets the relationship is -0.0077 (p-value 0.0000…
