What does this research mean for the field?

Most empirical claims in social science research based on a single topic model are not robust and are considerably distorted by defensible changes to modeling options such as preprocessing, cluster numbers, and algorithms. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate whether empirical findings derived from topic modeling in social science research remain robust across alternative, defensible modeling specifications.

Overview

Multiverse analysis reveals low robustness of empirical claims across published social science studies, highlighting vulnerability to researcher degrees of freedom.

Key Points

To evaluate whether empirical findings derived from topic modeling in social science research remain robust across alternative, defensible modeling specifications.
Applied a preregistered multiverse analysis framework to re-examine empirical claims from six previous social science studies using their Open Science materials.
Systematically varied defensible topic modeling choices, including text preprocessing options, the number of topic clusters, and selected topic modeling algorithms.
Observed that while a minority of specific empirical claims demonstrated robustness, most claims were distorted considerably when alternative modeling parameters were used.
Demonstrated that single-model topic analyses are highly sensitive to researcher degrees of freedom, supporting the broader adoption of preregistered multiverse analyses.
