Methodological rigor matters – but building valid instruments shouldn't take months. Measurement Intelligence combines triangulation, construct validity principles, and automated statistical analysis (IRT, polychoric correlations, reliability checks) so you can focus on insights, not infrastructure.

Why Cronbach's Alpha Is Not Enough

And what should be used instead "Cronbach's alpha was .83, indicating good internal consistency." This sentence still appears widely in articles, reports, and theses. It has become the standard way to report the internal consistency of a measurement instrument. However, being standard does not mean being unproblematic. Cronbach's alpha is based on assumptions that rarely hold in practical measurement. For this reason, alpha should be interpreted with caution. What alpha assum

Pragmatic Validation Without Experimental Design

Traditional instrument validation requires exploratory and confirmatory phases, large samples, and 6+ months. In applied contexts, this rarely happens. Triangulation offers a pragmatic alternative: when multiple independent measurement approaches converge, reliability increases without heavy methodology.
