I guess we’re all aware of the wave of texting while driving legislation, as well as recent moves in a number of jurisdictions to make the penalties more draconian. And it seems like a reasonable supposition that such legislation would reduce the incidence of accidents doesn’t it?

What is risk, how dow we categorise it and deal with it.
The above info graphic courtesy of Jeff Masters Wunderblog blog says it all, 6 out of the 13 most destructive superstorms have occurred after 1998.
Interestingly the study is circa 2011 but I’ve seen no reflection in Australia on the uncomfortable fact that the study found, i.e that all we are doing with such schemes is shifting the death rate to an older cohort. Of course all the adults can sit back and congratulate themselves on a job well done, except, well except it doesn’t work, and worse yet sucks resources and attention away from searching for more effective remedies.
In essence we’ve done less than nothing as a society to address teenage driving related deaths, safety theatre of the worst sort…
And not quite as simple as you think…
The testimony of Michael Barr, in the recent Oklahoma Toyota court case highlighted problems with the design of Toyota’s watchdog timer for their Camry ETCS-i throttle control system, amongst other things, which got me thinking about the pervasive role that watchdogs timers play in safety critical systems.
Why risk communication is tricky…
An interesting post by Ross Anderson on the problems of risk communication, in the wake of the savage storm that the UK has just experienced. Doubly interesting to compare the UK’s disaster communication during this storm to that of the NSW governments during our recent bushfires.
Or ‘On the breakdown of Bayesian techniques in the presence of knowledge singularities’
One of the abiding problems of safety critical ‘first of’ systems is that you face, as David Collingridge observed, a double bind dilemma:
- Initially an information problem because ‘real’ safety issues (hazards) and their risk cannot be easily identified or quantified until the system is deployed, but
- By the time the system is deployed you now face a power (inertia) problem, that is control or change is difficult once the system is deployed or delivered. Eliminating a hazard is usually very difficult and we can only mitigate them in some fashion.
Why saying the wrong thing at the wrong time is sometimes necessary
The Green’s senator Adam Bandt has kicked up a storm of controversy amongst the running dogs of the press after pointing out in this Guardian article that climate change means a greater frequency of bad heat waves which means in turn a greater frequency of bad bush fires. Read the article if you have a moment, I liked his invoking the shade of Ronald Reagan to judge the current government especially. Continue Reading…
The consensus project: Yes there is one on climate change
Despite what you may see in the media, yes there is an overwhelming consensus on climate change (it’s happening), what the cause is (our use of fossil fuels) and what we can do about it (a whole bunch of things with today’s tech). Here’s the link to the projects web page, neat info graphics…enjoy.
Oh and if like me you live in Australia I’d start getting used to the increasing frequency of extreme weather events and bush-fires, the only uncertainty left is whether we can put the brakes on in time to prevent a complete catastrophe.
Taboo transactions and the safety dilemma Again my thanks goes to Ross Anderson over on the Light Blue Touchpaper blog for the reference, this time to a paper by Alan Fiske an anthropologist and Philip Tetlock a social psychologist, on what they terms taboo transactions. What they point out is that there are domains of sharing in society which each work on different rules; communal, versus reciprocal obligations for example, or authority versus market. And within each domain we socially ‘transact’ trade-offs between equivalent social goods. Continue Reading…
