In this video, Professor Burkhard Schafer explains how data driven tools are increasingly being used by the justice system and seem to have an impact on the legal job market too. There is a short exercise to follow and, as background, Dr Schafer introduces you to the two main schools of thought in legal theory, formalism and realism - i.e the logical and the 'human' and how we continue to address the increasing use of data science to “predict” court decisions.
