I'll start.
I don't know if it's a culture. Personally, all the positions I've held have been in public organizations subject to the Access to Information Act. We were used to dealing with that. What's more, as academics, we like writing. We like to document our decisions so that they can be consulted, and we like research.
As I've told the chair of the board of directors on a number of occasions, I would sometimes have liked to have briefing notes to document the risks. Let's just say that the board was less inclined to produce such notes, except for programs and all that. For hotter issues, I would have liked to have had more complete notes on the balance of risks. It wasn't our practice to do this for hot issues. I'm not talking about programs.
