At lunch with two colleagues, we were talking about the need to communicate statistics clearly to the general public, and of the good work that David Spiegelhalter has done on this.

David Spiegelhalter of course.
(Spoiling the magic: DS was in a meeting at the RSS, which is around the corner from us, so this was not quite an unexpected meeting place.
