Precedents or Principles?
'I always buy this type of coffee.' But is that decision one of principle - or just because you buy it each day? Nick Chater asks which matters more to us: precedent or principles?
We firmly believe that our choices - about what we eat and how we vote - reflect the inner core of our being. But do those choices originate in principle - or simply because of what we have done in the past? Psychologist Nick Chater asks if precedent matters more than principles and discovers a complex interplay between the two forces which govern the choices we make.
