The National Threat Assessment (is rubbish)

National-Terrorism-Threat-Advisory-System

With much pomp and circumstance the attorney general and our top state security mandarin’s have rolled out the brand new threat level advisory system. Congrats to us, we are now the proud owners of a five runged ladder of terror. There’s just one small teeny tiny insignificant problem, it just doesn’t work. Yep that’s right, as a tool for communicating it’s completely void of meaning, useless in fact, a hopelessly vacuous piece of security theatre.

You see the levels of this scale are based on likelihood. But whoever designed the scale forgot to include over what duration they were estimating the likelihood. And without that duration it’s just a meaningless list of words. 

Here’s how likelihood works. Say you ask me whether it’s likely to rain tomorrow, I say ‘unlikely’, now ask me whether it will rain in the next week, well that’s a bit more likely isn’t it? OK, so next you ask me whether it’ll rain in the next year? Well unless you live in Alice Springs the answer is going to be even more likely, maybe almost certain isn’t it? So you can see that the duration we’re thinking of affects the likelihood we come up with because it’s a cumulative measure. 

Now ask me whether a terrorist threat was going to happen tomorrow? I’d probably say it was so unlikely that it was, ‘Not expected’. But if you asked me whether one might occur in the next year I’d say (as we’re accumulating exposure) it’d be more likely, maybe even ‘Probable’ while if the question was asked about a decade of exposure I’d almost certainly say it was,  ‘Certain’. So you see how a scale without a duration means absolutely nothing, in fact it’s much worse than nothing, it actually causes misunderstanding because I may be thinking in threats across the next year, while you may be thinking about threats occurring in the next month. So it actually communicates negative information.

And this took years of consideration according to the Attorney General, man we are governed by second raters. Puts head in hands.
