One of the trophes I’ve noticed in design projects over the years is the tendency of engineers to instinctively jump from need to a singular conceptual solution. Unfortunately that initial solution rarely stands the test of time, and inevitably at some crisis point there’s a recognition that this will not work and the engineers go back to change the concept, often junking it completely.

Human psychology and the role it plays in decision making under uncertainty.
How do we give meaning to experience in the midst of crisis?
Instead people strive to create a view of it by establishing a common framework into which events can be fitted to makes sense of the world, what Weick (1993) calls a process of sensemaking. And what is true for individuals is also true for the organisations they make up. In return people also use an organisation to make sense of what’s going on, especially in situations of uncertainty, ambiguity or contradiction.
Gregory (Scotland Yard detective): “Is there any other point to which you would wish to draw my attention?”
Holmes: “To the curious incident of the dog in the night-time.”
Gregory: “The dog did nothing in the night-time.”
Holmes: “That was the curious incident.”
What you pay attention to dictates what you’ll miss
The point that the great detective was making was that the absence of something was the evidence which the Scotland Yard detective had overlooked. Holmes of course using imagination and intuition did identify that this was in fact the vital clue. Such a plot device works marvelously well because almost all of us, like detective Gregory, fail to recognise that such an absence is actually ‘there’ in a sense, let alone that it’s important.
John Adams has an interesting take on the bureaucratic approach to risk management in his post reducing zero risk.
The problem is that each decision to further reduce an already acceptably low risk is always defended as being ‘cheap’, but when you add up the increments it’s the death of a thousand cuts, because no one ever considers the aggregated opportunity cost of course.
This remorseless slide of our public and private institutions into a hysteria of risk aversion seems to me to be be due to an inherent societal psychosis that nations sharing the english common law tradition are prone to. At best we end up with pointless safety theatre, at worst we end up bankrupting our culture.
In a slight segue, I was reading Bruce Schneier’s blog on security and came across this post on the psychology behind fraud. Bruce points to this post on why, yes I know, ‘good people do bad things’. The explanation that researchers such as Ann Tenbrunsel of Notre Dame offer is that in the same way that we are boundedly rational in other aspects of decision making so to are our ethical decisions.
In particular, the way in which decision problems were framed seems to have a great impact upon how we make decisions. Basically if a problem was framed without an ethical dimension then decision makers were much less likely to consider that aspect.
Additionally to framing effects, researchers found in studying collusion in fraud cases most people seem to act from an honest desire simply to help others, regardless of any attendant ethical issues.
What fascinates me is how closely such research parallels the work in system safer and human error. Clearly if management works within a frame based upon performance and efficiency, they are simply going to overlook the down side completely, and in a desire to be helpful why everyone else ‘goes along for the ride’.
There is as I see it a concrete recommendation that come out of this research that we can apply to safety; that fundamentally safety management systems need to be designed to take account of of our weaknesses as boundedly rational actors.
One of the perennial issues in regulating the safety of technological systems is how prescriptively one should write the regulations. At one end of the spectrum is a rule based approach, where very specific norms are imposed and at least in theory there is little ambiguity in either their interpretation or application. At the other end you have performance standards, which are much more open-ended, allowing a regulator to make circumstance specific determinations as to whether the standard has been met.

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.
I was reading a post by Ross Anderson on his dismal experiences at John Lewis, and ran across the term security theatre, I’ve actually heard the term, before, it was orignally coined by Bruce Schneier, but this time it got me thinking about how much activity in the safety field is really nothing more than theatrical devices that give the appearance of achieving safety, but not the reality. From zero harm initiatives to hi-vis vests, from the stylised playbook of public consultation to the use of safety integrity levels that purport to show a system is safe. How much of this adds any real value?
Worse yet, and as with security theatre, an entire industry has grown up around this culture of risk, which in reality amounts to a culture of risk aversion in western society. As I see it risk as a cultural concept is like fire, a dangerous tool and an even more terrible master.
