At its essence, credit scoring is a statistical method used by lenders to predict the likelihood that a borrower will default on a loan or fail to make payments on time.

This article explores the core tenets of Thomas’s work and examines how his foundational principles are being applied (or challenged) in today’s scorching fintech landscape.
A core thesis advanced by L.C. Thomas in his wider research at the University of Edinburgh's Credit Research Centre is the evolution of institutional lending goals. Historically, the primary objective of a scorecard was basic risk minimization—specifically, reducing the absolute number of loan defaults. Credit Scoring and Its Applications - Google Books
