Science will be part of the solution to every problem in the 21st century – and it will continue to illuminate humanity and humanity’s place in the universe. This means it is not enough for universities to train scientists to do science. Non-scientists need to be scientifically literate too. Scientific literacy involves more than knowing something of what scientists have already learnt. It also involves an appreciation of the importance of science for daily life, business, politics, our collective future and our view of ourselves. And, just as importantly, it involves an ability to evaluate the science reported to non-scientists and to draw sensible conclusions from it. It is impossible to do any of that without understanding how scientists grope and stagger forward, and how their efforts appear in the media. The aim of this course is to make the citizens and leaders of the future better consumers of science.
With extensive use of controversial case studies, we will help students develop a critical appreciation of the process of scientific discovery and its implications.
1. The meaning, use and diversity of the scientific method
- Science is both imaginative and highly disciplined
- Science is a very successful way to gain knowledge
- Science is a human endeavor and so is often flawed, yet it can in the long run draw powerful context- and culture-independent conclusions
- Why it works: organized skepticism.
- What conflicting evidence means and how we can sort it out (not all data are equal)
- Why there is no such thing as absolute proof in science
- What is meant by certainty in science – and how scientists convey it, and why it usually can’t be conjured up over night
- What science can and cannot deliver (knowledge and ethics)
- Why it is hard to aim science at a target
2. The difference between good science, bad science, pseudoscience and everything else; evidence versus conviction; skeptics versus deniers
- The impact of science on humanity’s view of humanity
- The enormous impact science will continue to have
- The contemporary utility of science for everyday life, for business and for governance
- Science is a civilizing enterprise that generates wonder and awe.
Related themes that bubble up along the way
- Humans have lousy intuition
- The more science reveals about the natural world, the more we realize just how little we know
- Why the public gets confused about science and why scientists get confused about the public
- Ability to recognise types of data that are more or less compelling (anecdote vs double-blind placebo trial; correlation vs causation)
- Ability to distinguish more and less reliable sources of information
- Ability to critically appraise science in the media
- Abililty to think probabilistically: risk, likelihood, error rates, degree of certainty
