I am reading Malcolm Gladwell's latest book right now, called Talking to Strangers: What We Should Know about the People We Don't Know, and I am intrigued by the chapter on Sylvia Plath's unfortunate suicide and the concept of "coupling." The idea behind coupling, which stands in contrast to displacement, is that when someone makes the very sad decision to commit suicide, it can often be coupled to a particular place or context.

Malcolm starts by giving the example of "town gas." Prior to it being phased out in the 1960s and 1970s, most homes in Britain relied on a form of gas that contained carbon monoxide. And sadly, it became the most popular way for people to kill themselves. When Sylvia Plath took her own life in 1962, the death-by-carbon-monoxide-poisoning stat was 44.2% of all suicides in England and Wales.

The concept of displacement, on the other hand, surmises that if somebody wants to kill themselves, they will eventually find another way. But Malcolm convincingly argues that that is not necessarily or very often the case. As town gas was phased out of British homes, the number of suicides also declined in lockstep. Turns out that many of the previous suicides had been coupled to that particular tool.

Why this is potentially valuable to this blog audience is that this same coupling phenomenon can happen within our cities and to particular places. Malcolm gives the example of the Golden Gate Bridge in San Francisco, which has been the site of many suicides since it was first erected in 1937. The same, of course, can be the said about many subway systems around the world.

But again, there's evidence to suggest that if you can save somebody on the Golden Gate Bridge (a suicide barrier was erected in 2018) or on a subway system by installing safety doors, there's a good chance that many of those people will never actually find another way to commit suicide. In other words, you can save a bunch of lives by having the right provisions in place and not assuming that something is a foregone conclusion.

Sadly, Japan has one of the higher suicide rates in the world. According to the World Health Organization, the rate from 2000 to 2016 was about 18.5 deaths per 100,000. The only country in Asia with a higher rate is South Korea. They are at 26.9 deaths per 100,000 (an alarming figure). For comparison, Canada and the US are at 12.5 and 15.3, respectively, which also seem rather high to me.

I was intrigued to learn today that one of the ways that Japan has been trying to combat this high figure is by installing blue LED lamps on some of its railway platforms. Blue lights have been proven to have a calming effect (compared to white light). And since jumping in front of a train is unfortunately a common suicide method, blue lights were thought to maybe be a cost effective alternative to platform screen doors.

The first blue station lights were installed on Tokyo’s Yamanote line in 2009. And according to this 2013 study – which looked at the possible impact across 71 train stations in Japan – the introduction of blue lights actually resulted in an 84% decrease in the number of suicides. Further studies also showed that there were no corresponding increases at other non-blue light stations. 

It is an interesting example of “nudge theory”, but does it get at the root of the problem?
