Minimalst Mistakes - Beautiful but flawed.

I love minimalist products. Ergonomists love simplicity. However, Ergonomics is about designing tasks for people, rather than having them adapt to the task. Quite often the most eloquent designs that appear to make life easier will have most obvious design flaw to an ergonomist that the most elegant designer just cannot see.

This beautiful, but flawed scandinavian table called MILK is one such design.


It beautifully hides the cords of computers to create a clear work surface and provides for custom designed storage of items. It's even electronically height adjustable, which could be useful if the desk is used by multiple users or for tasks other than computing However, it has 2 fatal flaws:

1. The single suppot pole is where your legs are supposed to be! Being able to move you legs around is central to adopting a variety of postures in long computer work to stop you getting stiff. This position of the pole will likely cause you to either continually kick the podium until you just keep your legs curled up under your chair.The result, stiff legs and a sore back.

2. The desk depth means that most people would not be able to adjust it low enough so that you can still fit your thighs under the desk but not have your shoulders hunched. The result, sore shoulders from long typing.

Very few changes are needed to make this the perfect desk. However, at the moment, the undercover ergonomist says save you hard earned 10k, or whatever, such a sleek design cost and buy a piece of wood with four legs you can cut off at a good height!

No-drop domestic violence - An Ergonomics Look at Behavioural Economic Analysis

This is a really intersting article over at nudge about a behavioural economic analysis of domestic violence relationships. But to think it has totally answered the question isn't right. I'm not suggesting that what the authors have claimed to have done.

The article is about changing making domestic violence changes "no-drop". Once the charge is made by a person (usually a woman) then they cannot drop the charges. The human factors question with regards to this what impact it will have on reporting. Persons against no-drop policy would presumably mention that it is potentially a deterant to some women reporting. Advocates would presumably say that by making a policy no-drop women will not be able to drop their charges after they are lured back into an abusive relationship - making it more likey that the cycle is broken.

The authors report that states in America that introduced the no-drop policy have seen an increase in reporting rates (14-18 percent) and a decrease in the number of women murdering their husbands/partners. They also report that there was no decrease in women presenting at hospital. Basically they say it doesn't deter men from bashing their wives however, it doens't deter women from reporting and, due to the lower murders which would presumably be in many causes where a woman sees no other way out, is breaking the cycle of abuse.

However, I think there are whole in this line of arguement when you start treating the women an humans. There are a wide range of abusive relationships, and differnet types of women, and treating a simple increase in reporting is probably not the right indicator. In short the human factor is in play. As always.


My fiancee is a procecutor and, from what she's said to me about procecuting domestic violence, there might be some issues with the results of the report. In short the 15 percent increase in reporting is definately a good thing, on the surface. However, another, and better, variable is an increase in successful procecutions for domestic abuse taking into account the reports claim that abuse is not decreasing.


Procecutors very regulaly have issues with victims of domestic abuse dropping charges. The point of the no-drop policy is to stop this. However, having a no-drop policy does not necessarily reverse this. Domestic abuse is very often one word against another and the no-drop policy does not ensure that the victim of domestic violence will, eventually, be co-operative when it comes to a trial. If they are not co-operative then a successful procecution is not likely. Therefore, even if the charges cannot be dropped the result of the policy it might simply be an increase the rate of unsuccessful procecutions.

Even worse, it 'could' potentially decrease the rate of sucessful procesutions. This is because there is the assumption in the statistics that the increase in the percentage of persons reporting domestic violence are all 'new' people. They reality is probably more likely to be a mix of a some women being detered from reporting, but a larger number of women reporting.

If this is the case it is certainly possible that the women deterred from reporting by the policy are the ones that need some external support and, once they get it, are more likely to follow through with a procecution. On the flip side the women increasing the reporting may be though in mutually abusive relationships. In short, one women being abused is not the same as the next. They are human.

You have to remember to measure the right things when 'peoples' decisions are involved and I think that the researchers, even in behavioural economics, still treat people a robots. Still the reduction of women killing their domestic partner and an increase in reporting is a good start. Therefore, this issue certinaly deserves further attention and debate. However, using this as total evidence that a no-drop policy will assist women is premature.

Inspirations

I figure that it's worth noting some well know and less well known inpirations for this blog - mainly so I remember myself why I started it.

Some of the more popular easy read books related to the topic:

Dan Gardner: Author of Risk - The Science and Politics of Fear.

Richard Thaler and Cass Sunstein: Authors of Nudge.

Donald Norman: Author of The Design of Everyday Things and Emotional Design.

Dan Airley the author of Predictably Irrational

Kim Vicente author of The Human Factor

The Undercover Ergonomist's Humble Start

The Undercover Ergonomist Begins!

Obviouly the the title is a play on the popular "Undercover Economist", British Economist and Author Tim Harford, who uses economics to analyse everday situations. Tim believes in the power of game theory to explain everyday situations. The Undercover Ergonomist, whilst not totally refuting this view, will attempt to examine how the imperfection of people interacting with the environment shape the human experience.

That said, this is not a blog about economics but ergonomics. The term comes from the Greek words ergon (labour, work) and nomos (law, rule). The aim of ergonomics is to make it easier for people to use tools and other objects. Ever not been able to use a lift? Open a door? Make a Website work? Hopefully, it will result in a intersting and readable blog that show the imporance of considering human limitations to, in small and large ways, improve our world.
