Ripped off because we don’t do well at math

I'm in the process of reading Stopped Getting Ripped off: Why Consumers Get Screwed, and How You Can Always Get a Fair Deal, by Bob Sullivan (2009). He starts off by asking you to pretend that you are in a restaurant and you are presented with a menu that he illustrates on page 5 of his book. You are asked to assume that you ordered the onion soup (the price is clearly listed on the menu as $.60) and the "Lancaster Special Sandwich" (the price is clearly listed on the menu for $1.95). The question he asks is this: "How much should you leave for a 10% tip? I'll wait for a bit while you do your calculation in your head. No calculators, please. What did you come up with? [more . . . ] The answer is 25.5 cents, so either 25 cents or 26 cents would be an acceptable answer. What Sullivan next states is shocking:

If you answer this question correctly, consider yourself part of an elite group, because when the US Department of education asked US adults to answer it as part of a nationwide study, only 42% answered correctly. Less than half of American adults were able to pick two numbers from the list, add them, then perform the most basic of all percentage calculations--simply moving the decimal point one column to the left to calculate 10%.

Innumeracy is literally killing us. Try to think of a major issue facing our country that does not require a basic proficiency in mathematics that most of us don't seem to have. Think of the environment, energy, national budget, climate, health care, evolution being taught in public schools, space exploration, public health issues (e.g., the importance of vaccinations), the true cost of the "war on drugs," reform of financial institutions or taxation policy. Since most Americans cannot understand how to calculate a 10% tip, there is little chance that they could meaningfully participate regarding most of the big issues facing our country. These are truly painful words to write. Just think of the many math-related claims that got math-ignorant voters excited during the last presidential election, including Sarah Palin's claim that American could live long and prosperously on Alaskan oil (when straight-forward calculations based on known reserves showed that there is only enough Alaskan oil to supply America's current rate of use for six months). Imagine how different things would be if most Americans could actually calculate the minimal chance that they would be affected by an act of terrorism, and if they were able to compare that risk to the immense numbers of lives that could be saved by much more modest expenditures. But it's not even clear whether most Americans can benefit from further training regarding statistics. It's certainly true that many health care professionals don't adequately understand basic problems involving risk. The reasons so many of us are innumerate are not easily addressed. We desperately need proficient math skills to tamp down our fears. I know it has been tried (and abused) before, but a sinister thought enters my mind. The information presented by Sullivan makes me wonder whether we should make voters take and pass a rudimentary math test before allowing them to vote. How indignant could a rejected voter be if he/she can't figure out a ten percent tip? Understanding the many math-based claims asserted by candidates is sometimes the only way to see past their slick acting abilities. I'm not seriously suggesting a poll quiz, though I'm sure that my frustration is showing through. What we really need to do is provide better math education all the way through school. It appears that we are paying dearly for the many grade schools that fail at math education, individually and as a country.

Can you tolerate NAMBLA?

image courtesty of the Federal Art Project, via Wikimedia Commons You think you're open-minded? What if the North American Man-Boy Love Association wanted to distribute a newsletter in your town? What if they wanted to hold a local parade celebrating pederasty? I am currently studying social psychology in graduate school, and I'm particularly interested in political psychology. One of my present research interests is political tolerance. "Political tolerance" refers to individuals' willingness to extend equal civil liberties to unpopular groups. When political scientists and psychologists measure political tolerance, they often probe individuals for their ability to withstand the most offensive, outlandish groups and speech possible. For example, a liberal-minded person may be asked whether they would be willing to allow a rally for the Klu Klux Klan or some extremist, militaristic group. Paradoxically, a truly tolerant person must be willing to allow racially intolerant speech. Political tolerance plays a cornerstone role in functioning democracies (at least, we think so). If voters can strip away the civil liberties of disliked political groups, those liberties lay on precarious ground indeed. If we cannot tolerate the words of anarchists or members of the Westboro Baptist Church, then we do not really believe in the boundlessness of speech at all. Academics say as much. In reality, voters are not so tolerant.

Tricking news providers to report on serious issues.

It’s certainly not breaking news that the commercial news media tends to abhor careful detailed rational discussion. This reluctance of local media outlets to report meaningful news has been going on for many years. But what is “news”? In my opinion, the most important news is information that sheds light on the way our community functions. High quality “news” informs us of the way our government is working. It warns us of collective dangers, including those dangers that we will face in the distant future. It gives us the information we need to take steps to protect ourselves, both as individuals and as a community. It is skeptical of outrageous claims, and honors the scientific method. It repeatedly reports on information that many viewers/readers might find inconvenient or disturbing, although it also balances this with information that makes us celebrate the state of our community and nation. Reporting the “news” accurately means holding up a big mirror to viewers/readers, and those who report accurately will work hard not to be community cheerleaders who filter out “bad news,” no matter how much they want to please, distract or entertain the audience. Couple this definition with the fact that the most serious issues of the day are unwieldy. They are either legally or factually complicated, or they have been so corrupted with political spin, that reporting on the issues meaningfully will require long hours of one or more aggressive veteran reporters who are constantly being supported by his/her editor and employer. I recently attended a conference sponsored by True Spin. My take-away is that that the majority of what passes for local “news” is starkly at odds with the above definition of “news.” Mason Tyvert summarized the types of things that are now required to pass as “news”:

Against all odds: How marijuana was legalized in Denver

If your quest were to convince the people of your city to legalize a highly demonized drug which was entirely safe, how would you run your campaign? At the recently concluded True Spin Conference in Denver, I had the opportunity to listen to an animated yet highly focused Mason Tvert describing for the audience how he and his small and not-well-funded organization (“SAFER”) convinced the people of Denver to legalize marijuana in 2005, with 51% of the people voting in favor. He also spearheaded a 2006 campaign to legalize marijuana throughout Colorado. Although that latter measure failed, an astounding 41% of the people of Colorado voted in favor. In case you’re thinking that I’m promoting the use of marijuana, I am not, but neither would I attempt to prohibit any other adult from using it. I’ve never used marijuana (even though I once worked as a musician and the opportunities were ubiquitous. Millions of gainfully employed and otherwise law abiding people do like to use marijuana, but they are paying dearly for their attempts to feel good and seek stress relief. I am for the legalization of marijuana because that our country arrests more than 750,000 people each year for possessing or using an extremely safe drug that successfully makes people feel good. This destructive and expensive waste of government law enforcement is absolutely shameful. The number of people arrested each year is more than the entire population of South Dakota. and these users include many people you know and respect. There is rank hypocrisy in the air, given that marijuana inexpensively offers the harmless escape that most of us seek much of the time (in one way or another), without any serious side effects and without the expense of many other methods of escape. If there were no such thing as marijuana, when it was finally invented by a pharmaceutical company, we would hail it as a miracle drug (Big Pharma wouldn’t need to lie about its efficacy or safety, as it does for many other drugs). Governments would allow it to be sold at drugs stores and they would happily tax it.

Image by Rohan Kar, courtesy of Wikimedia Commons I was mulling around the Lincoln Park Zoo today with a friend when a man stepped on me. He was filming a Siberian tiger with a high-end digital video camera, which he held on an expensive mounting. He was fidgeting with all of the camera's features, backing up to get the perfect shot, and he stepped all over my feet. The foot-stomping didn't bother me so much as the man's intent focus on something other than his present surroundings. A beautiful creature stood before him, but his attention was directed at the camera and the filming of the tiger more than it was the tiger itself. Not much later, something similar occurred in the Tropical Birds House. As I was watching the bleeding-heart pigeons, a man, family in tow, came around the corner with a massive video camera. He also had it placed on an expensive mount. Obliviously, he nudged forward until his lens nearly leaned on the display's glass. He fiddled and fidgeted. He zoomed on the critters for a moment, and left. "Do you think he'll ever watch that footage?" my friend asked. "No," I guessed. Without much thought I noted, "It isn't about the footage. He probably just bought that camera, and is filming because he wants to play with it." "So the actual footage is useless," he observed in return. I intuited that the man's camera was a new purchase because I've done the exact same thing with a fresh 'toy'.
