Conservation of Threat

Here’s some interesting research about how we perceive threats. Basically, as the environment becomes safer we basically manufacture new threats. From an essay about the research:

To study how concepts change when they become less common, we brought volunteers into our laboratory and gave them a simple task ­– to look at a series of computer-generated faces and decide which ones seem “threatening.” The faces had been carefully designed by researchers to range from very intimidating to very harmless.

As we showed people fewer and fewer threatening faces over time, we found that they expanded their definition of “threatening” to include a wider range of faces. In other words, when they ran out of threatening faces to find, they started calling faces threatening that they used to call harmless. Rather than being a consistent category, what people considered “threats” depended on how many threats they had seen lately.

This has a lot of implications in security systems where humans have to make judgments about threat and risk: TSA agents, police noticing “suspicious” activities, “see something say something” campaigns, and so on.

Needless Panic Over a Wi-FI Network Name

A Turkish Airlines flight made an emergency landing because someone named his wireless network (presumably from his smartphone) “bomb on board.”

In 2006, I wrote an essay titled “Refuse to be Terrorized.” (I am also reminded of my 2007 essay, “The War on the Unexpected.” A decade later, it seems that the frequency of incidents like the one above is less, although not zero. Progress, I suppose.

Testing for Explosives in the Chicago Subway

Chicago is doing random explosives screenings at random L stops in the Chicago area. Compliance is voluntary:

Police made no arrests but one rider refused to submit to the screening and left the station without incident, Maloney said.

[…]

Passengers can decline the screening, but will not be allowed to board a train at that station. Riders can leave that station and board a train at a different station.

I have to wonder what would happen if someone who looks Arab refused to be screened. And what possible value this procedure has. Anyone who has a bomb in their bag would see the screening point well before approaching it, and be able to walk to the next stop without potentially arousing suspicion.
