In this course of 6 sessions, Dr Mark Perkins explores the theory and practice of critical thinking in terms of recognising bias (cognitive and emotional), using data critically, and building powerful, informed, and balanced arguments. Each session is in two parts. In Part One, Mark will briefly present an aspect of critical thinking, and in Part Two, the participants will be able to work through concrete examples and practise their critical thinking skills. The examples are based on current topics such as deep fakes, AI and the arts, overtourism, and the circular economy. Mark Perkins is the President of Cambridge Valid. He publishes on his own account and also has a publication program on AI, education, and ethics together with the Polish Academy of Sciences.
