ABSTRACT
Commentary articles can go one of two ways. Either they can stick to the orthodoxy; the path well-travelled, and embrace summary rather than synthesis. Or, the issues in play can be seized upon as an opportunity to provoke debate, stress-test ideas, and if fortune really does favour the bold, to send our thinking in new directions. Clearly there is only one option here. In this commentary, I would like to stand back and think about our underlying operating assumptions because these are rarely questioned yet have a profound effect on our methodologies.
