A short epistle today, I'm worn out by enquiries and reports and all that stuff. Also by the endlessly proliferating wars around the world. There's a rule in senior levels of public services around the world: Never hold an enquiry unless you're sure you can get the answers you want. The show must go on, but make sure it doesn't blow up in your face. The report of the Senate enquiry into ADHD, released a week or two ago, is a neat example of the genre: Ask a series of loaded questions, then invite a gaggle of people whose minds are made up to answer them. As theatre, it's a winner, and that's all this enquiry was, a diversion, a distraction and a total waste of public time and money. However, a lot of people around the country are feeling very satisfied, believing they're going to get what they want. Well, beware of what you wish for. I've had my fill of ADHD this month, we'll come back to it another day, but one small point on p137, almost a throw-away, caught my eye.
