Why do causal designs rely so much on quantitative research techniques?

Causal designs rely heavily on quantitative research techniques because these methods allow for precise measurement and statistical analysis of relationships between variables. Quantitative techniques facilitate the identification of cause-and-effect relationships by enabling researchers to control for confounding factors and establish statistical significance. Additionally, the ability to generate numerical data enhances the replicability and generalizability of findings across different contexts. Ultimately, quantitative methods provide the rigor necessary to draw valid conclusions about causal relationships.
