Boom Box Illusion

Three-dimensional illusions can be public art and can even have practical uses.

This one – audio tape to boom-box tape player – is art, artifice, for art’s sake. No sociological content, but it’s just so cool.



A video with more detail on how it was done is here.

Who Are the Felons in Your Neighborhood?

Do most of us know the crime statistics for our neighborhood?

In a comment on the previous post, Bob S. asked, “If people knew how many index crimes were in their neighborhoods, do you think there would be more involvement in handling the issues before governmental interference?”

The point of my post had been that our estimates of crime are impressionistic, and those impressions are much more affected by the appearance of a neighborhood than by numbers on the police books. The “signs of crime” – abandoned cars and buildings, tough-looking groups of kids, garbage strewn on the sidewalk, etc. – are visible, and you can see them every day. When I was in the crim biz and the newspaper would publish crime statistics once or twice a year, I’d note the numbers for my precinct, and I’d clip the article and file it. A week later I wouldn’t remember whether robberies or other crimes in my neighborhood were up or down from the previous year.

That was before the Internet. Now, some cities make their crime data easily accessible. Here, for example are the crimes known to the police for the last six months in the area of Boston where my niece lives.

A is for Assault, B for Breaking and Entering, R for Robbery, T for Theft, and so on. You can select the time period, and you can click on an incident for more detail.

Houston too has a user-friendly site. You choose the area of the city you want. The map shows and describes the boundaries, and it lists the zip codes in that “beat.” Another click takes you to a list of all crimes in any month you choose – type of crime and address.

At the NYPD Website, you can get data by precinct for the seven Index crimes for the most recent week. If there’s an option for other time periods and details about location, I couldn’t find it.

If you're interested, try your own city. Googling the city name and “police department” will get you there. Then see what kind of information you can get about your neighborhood.

Then there’s Bob’s question about knowledge of crime and ideas about the role of government. I don’t have good data at hand, but my guess is that most people still see crime as a matter for government, especially when crime rates are high. Individuals and businesses may adopt preventive measures, but when crime becomes a public issue, most people look to the government and its agencies – the police and courts. When people are afraid – of crime, terrorism, communism, drugs, illegal immigration, etc. – they look to the government for protection. When people think that crime rates are rising, they’re willing to grant more power to the state. It’s only when they perceive the government as incapable of protecting them that they turn to vigilantism and other non-state protection schemes. Even then, they see their activity as supplementing government action, not replacing it.

Taking Less Serious Crime Seriously

City Keeping Minor Crimes Under Radar

That was the headline on a front-page, above-the-fold story Tuesday’s Times. It reported that since 2002, the city and police department have stopped providing the data to the state, or presumably to just about anyone else. The NYPD readily publishes its data on “serious crime” or what the FBI calls Part I crimes.* These are also known as the “Index” offenses because they supposedly serve as an index or indicator of general levels of crime. But in addition to these seven or eight crimes (depending on whether you count arson), cities also keep statistics on Part II crimes. Here’s a page from the Phoenix Police Department report.

(Click on the image for a larger view. Or go here for the original.)

The Times couldn’t find anyone at the NYPD to justify the policy. The story does quote a City Council member who was trying to force the issue. “They basically said the public can’t handle this information.” (Apparently Jack Nicholson was on duty when she asked.)

I myself don’t know what to make of Part II numbers. Some of these less serious crimes are important, not for any direct harm that they cause but for their impact on people’s general sense of fear or safety. That feeling is not much related to rates of serious crime (murder, robbery, car theft, etc.). These crimes usually occur where few people can see them. Our sense of safety is far more affected by visible but less serious crime and even things that are not crimes. Abandoned cars, run-down buildings, street prostitutes, drug dealers, and gangs – we read these as signs of crime. These are the true index offenses – they are our indicator of how safe a neighborhood is.

The trouble is that statistics on these offenses are much more driven by what the police do than by what the offenders do. An increase in drug offenses on the books probably means that the police have decided to crack down on that crime. Look at the Phoenix data. Has there been virtually no illegal gambling in Phoenix in the last decade? Did DUIs really double from 2006 to 2008?

Cracking down on these signs of crime is the whole idea behind the “broken windows” approach. In its original version, the idea was that if the police got tough on “disorder” and “quality of life” offenses, more serious crimes would also decrease. I haven’t kept up with the research on this, but my guess is that “broken windows” enforcement has at best a modest impact on crime, but it goes a long way towards making people feel safer.


* Recently, some researchers have raised doubts about the accuracy of the NYPD’s statistics. See previous posts here and here.

Ignoring Good News

November 2, 2010
Posted by Jay Livingston

I’m writing this before the polls close, but like everyone else, I expect this to be an anti-Obama election. And like most people, I think the reason is the economy. But . . .

  • Obama has lowered taxes for almost all Americans.
  • Most of the TARP money for Wall Street has been recovered, and the country will make about $16 billion in profits from it.
  • The economy has grown by 3% in the past year, the Dow and S&P are up for the year.
In thread on a previous post, there was some discussion about ignorance – what people know, and what they think they know but are wrong about. A Bloomberg poll today showed that most people
  • believe taxes have increased
  • think the TARP money has disappeared down the drain (or into the bankers’ pockets)
  • think the economy has been shrinking
The ignorance on these items is, of course, greater among Republicans. But many Independents and Democrats also share the erroneous perceptions.

Why? The head of the company that did the poll blames the Democrats for their failure to communicate the good news. My guess is that it’s more like a halo effect, or what Bruce Oppenheimer (political science, Vanderbilt), quoted in the article, calls “a dark cloud.”

The halo or cloud is the overall global impression that people form. From that general perception they deduce the specifics. If your overall impression is that the economy sucks, then you'll guess that anything that has to do with the economy is going the wrong way – taxes going up, the economy shrinking, the big bad bankers getting away with robbery, etc.

Oppenheimer thinks that the dark cloud is unemployment. True, no doubt. I suspect that real estate – home values and sales – also plays a part. It’s not just that people pay more attention to bad news than good. But the information on TARP, growth, and even taxes is more remote. Taxes you pay only once a year. Does anyone make close comparisons of the deductions in their check stubs from last year? TARP – would anyone have first-hand knowledge of that?

But if you own a home, you might know about its value. And you can see empty, unsold houses with the naked eye, “For Sale” signs lining the streets like Burma-Shave signs. Unemployment isn’t just a number like 9.5%. If you’re out of work, or if you know people who can’t find a job, it’s right there in the room with you, and you just might not care all that much about GDP numbers or the stock market.

Update: I heard about this survey only today. Turns out it was released three days ago and covered in a few places including WaPo and NPR. That same day, David Dayen at FireDogLake had the same reaction that I did today. Or as he put it, the survey showed “that Americans don’t pay attention to CBO or NBER reports or watch C-Span very often.”
