This letter questions Woodberry's (2012) claim linking conversionary Protestantism to stable democracies globally. By using 26 alternative democracy measures and averaging data over a longer time period, the analysis finds no significant relationship between missions and democratization.

Methodological Challenges:

* Employed multiple independent democracy indicators instead of relying on one

* Extended timeframe for measuring democratic outcomes

Findings:

The replication fails to support Woodberry's original results. The evidence does not demonstrate a connection between Protestant mission activity and the establishment or stability of democracies.

Robustness Concerns:

This lack of finding raises questions about the overall robustness and broad applicability of Woodberry's research.
