The theories one uses needs to be explicit, especially when the issue is as complicated as Brexit or Trump.

Two of my intellectual mentors, Maynard Keynes and Karl Popper, give broadly the same advice. Be aware that you are using theories; be sensitive to their assumptions, to their limitations. Very often our public discussions involve no awareness of the underlying theoretical constructs, let alone their weaknesses (as well as their strengths).
