Certain Types of Brain Damage Can Improve Utilitarian Moral Judgments, Research Shows

PASADENA, Calif.—Quick response! What's the best thing to do on a lifeboat with one too many people on board? Should one throw a mortally injured person overboard to ensure definite survival for everyone else, or refuse to act and ensure certain death for all individuals in the boat?

For most of us, the biggest stumbling block is the word "quick." Many of us will eventually concede that the greatest good for the greatest number of people is the only reasonable alternative, and that the injured person will have to be thrown overboard. However, we typically blanch at grim decisions involving actions that in other contexts would clearly be deemed immoral. Some people, in fact, never reach the utilitarian conclusion, saying that they would not be able to throw the injured person overboard, regardless of the final outcome.

But new research reveals that there is one type of person who can quickly reach the decision to act in the greater interest of the majority—the person who has suffered damage to an area of the brain known as the prefrontal cortex. In the current issue of the journal Nature, researchers from the California Institute of Technology, Harvard University, the University of Iowa, and the University of Southern California report that experimental tests on patients with prefrontal cortex damage reveal for the first time that emotions play an important role in feelings about what is right and wrong.

According to Ralph Adolphs, who holds joint appointments at Caltech and the University of Iowa Department of Neurology where the patients were tested, the results are important because they transfer the study of moral judgments from the realm of philosophical speculation to the realm of the experimental laboratory.

"The idea that emotions play a part in moral judgments is not new, but our study gives a stronger conclusion because it involves data from lesion subjects," says Adolphs.

The experiment was performed on six patients who have had tumors removed from the prefrontal cortex, 12 patients with other types of brain damage, and 12 healthy subjects. Each of the 30 test subjects was asked 50 questions involving moral dilemmas. Each question required a "yes" or "no" response, and the questions varied from easy nonmoral to very agonizing moral dilemmas (like throwing the person out of the lifeboat).

By significant margins, the six test subjects with prefrontal cortex damage were able to quickly arrive at the utilitarian response that saved the greater number of people. All the others had difficulty making those choices, and occasionally were unable to provide a "yes" answer even when the "no" scenario for action led to a greater number of people being injured or killed.

"These patients' judgments are different from the comparison subjects' judgments specifically for these high-conflict personal moral dilemmas," Adolphs explains. "Because of their brain damage, they have abnormal social emotions in real life, and lack a normal concern for the well-being of others. In other words, they lack empathy and compassion.

"So patients with prefrontal damage usually say it's preferable to throw the injured person overboard, and they don't have the conflict between emotion and reason that other people have."

The conclusion is that emotions indeed play a role in moral decisions, especially those involving questions of whether the end justifies the means. In short, the people with the brain damage are quickly able to "do the arithmetic" that determines who lives and who dies.

Adolphs is the Bren Professor of Psychology and Neuroscience and professor of biology. The lead authors of the study are Michael Koenigs and Liane Young, at the National Institute of Health and Harvard University, respectively. The other authors are Daniel Tranel of the University of Iowa, Fiery Cushman and Marc Hauser, both of Harvard, and Antonio Damasio, formerly of the University of Iowa and now at the University of Southern California.

The title of the paper is "Damage to the Prefrontal Cortex Increases Utilitarian Moral Judgments."

Watson Lecture: European Conquest

PASADENA, Calif.--How did the West conquer the world? The secret, says California Institute of Technology economic historian Philip T. Hoffman: technological innovation.

Between 1500 and 1914, European states conquered 84 percent of the globe, although the weapons they employed--gunpowder and firearms--were invented in China and were long used in other parts of Eurasia. Why didn't the Chinese, the Japanese, or the Ottomans perfect this technology?

Using economic calculations, Hoffman measured the European advantage and concluded that European political institutions drove military innovation with incentives much like those at work today in Silicon Valley. "The rates of technological innovation were far higher than you'd expect before the industrial revolution, and similar to what you see today in the computer industry," he says. Military adventures had potentially great rewards for decision makers, with very little penalty for failure. As a result, "you had excessive investment in this sector of the economy."

On Wednesday, December 6, Hoffman, the Richard and Barbara Rosenberg Professor of History and Social Science at Caltech, will discuss his findings in "Why Did Europe Conquer the World?" The lecture will be presented at 8 p.m. in Beckman Auditorium, 332 South Michigan Avenue, south of Del Mar Boulevard, on the Caltech campus in Pasadena. It is the third program of the fall/winter 2006-07 Earnest C. Watson Lecture Series. Seating is available on a free, no-ticket-required, first-come, first-served basis.

Caltech has offered the Watson Lecture Series since 1922, when it was conceived by the late Caltech physicist Earnest Watson as a way to explain science to the local community.

Caltech and Princeton University Press Release Tenth Volume of the Einstein Papers

PASADENA, Calif.-In the latter half of 1920, Albert Einstein faced a series of increasingly acrimonious public attacks against his recently confirmed theory of general relativity. He considered leaving Berlin, which would have deprived Germany of its most famous scientist. Colleagues, friends, and unknown admirers offered support, while Einstein worried about the care of his two sons and ex-wife in Switzerland, and his new family in Berlin.

This is the historic context of the tenth volume of The Collected Papers of Albert Einstein, which is being released this week by Princeton University Press under the editorship of the Einstein Papers Project at the California Institute of Technology.

Volume 10 contains Einstein's correspondence from May to December 1920, as well as a substantial number of previously unavailable letters from 1909 to 1920, most of them written by Einstein. These originate from the bequest of family correspondence deposited at the Albert Einstein Archives at the Hebrew University in Jerusalem by his stepdaughter Margot Einstein, who stipulated that they remain closed for twenty years after her death.

The volume presents letters written by Einstein's young sons Hans Albert and Eduard Einstein in which they report on their hobbies and reading and express their longing for the absent father. It also includes for the first time since Volume 1 a number of letters written by his wife, Mileva Einstein-Maric. The largest group of supplementary letters, written by Einstein between April 1916 and October 1919, mainly in the form of postcards and resembling a travel diary, is addressed to Elsa Einstein, his cousin and future second wife.

It also contains new information on Einstein's personal life during the last eight months of 1920, such as his first vacation with his sons in Southern Germany and his renewed attempts to move his Zurich family there. We also gain a glimpse into the unique perspective of Elsa Einstein, in the few extant letters, of her relationship to Einstein.

In addition, in letters newly available at the Central Library in Zurich addressed to his friend Heinrich Zangger, Einstein confides on personal matters, worries, and family crises, his negotiations with Mileva Einstein-Maric, his feelings about his sons, the separation, divorce, and contemplated second marriage. The war, his opposition to it, and his sense of alienation from some of his academic colleagues in Berlin come to the fore, as do the difficulties of crossing international borders, the widespread hunger, and economic hardships.

The second half of Volume 10 finds Einstein full of optimism about Germany's new democracy. He vigorously promotes general relativity and the endeavors of other scientists toward its further confirmation. We see Einstein firmly positioned as a central figure in the lively cultural atmosphere of the young Weimar Republic, as witnessed by correspondence with renowned German philosophers of the time, such as Ernst Cassirer, Hans Reichenbach, and Max Wertheimer.

Scientific issues are discussed in the correspondence as well, shedding light on his associations with fellow physicists in Europe and the United States, and his lectures on the special and general theories of relativity within Germany and during his trips to Holland, Denmark, and Norway. The documents present the challenges Einstein faced as a result of his recently acquired celebrity status, his subsequent entrance into the public arena, and the contentious public attacks against relativity.

The intensity of this period, during which anti-Semitism and nationalistic sentiment seeped into scientific debate, is reflected in numerous letters. The successful completion of the intricate process of Einstein's appointment as Special Professor at the University of Leyden leads to his well-known inaugural lecture on "Ether and Relativity" in October 1920. The letters document in detail his sojourns in the Netherlands, the hospitality of many Dutch colleagues, his involvement with issues at the forefront of physics, and especially his significant intellectual and personal bonds with Paul Ehrenfest. He visits Oslo and Copenhagen, where he meets with Niels Bohr, and receives invitations to America.

The Collected Papers of Albert Einstein, a collaborative project with participants from several countries, are edited by Diana Kormos-Buchwald, a professor of history at Caltech; Tilman Sauer, a senior research associate in history; Ze'ev Rosenkranz, Jozsef Illy, and Virginia Iris Holmes, members of the research staff in the Einstein Papers Project; and by associate editors Jeroen van Dongen, Daniel Kennefick, and A.J. Kox.

Watson Lecture: Puzzling Prices

PASADENA, Calif.- Ever wonder why gas prices can vary by 15¢ --or more-- over a two-mile drive, or why an airline will change the cost of fares 500,000 times per day? Curious about what determines prices in the first place?

R. Preston McAfee of the California Institute of Technology has examined these mysteries, and provides an explanation: a concept called "price discrimination," which essentially means charging each customer what the market can bear.

On Wednesday, May 3, McAfee, J. Stanley Johnson Professor of Business Economics and Management and executive officer for the social sciences, will delve into the oddities of business pricing using examples from IBM, airlines, and more, in his talk, "Why Are Prices So Bizarre?" It is the third program of the winter/spring 2006 Earnest C. Watson Lecture Series.

The talk will take place at 8 p.m. in Beckman Auditorium, 332 S. Michigan Avenue south of Del Mar Boulevard, on the Caltech campus in Pasadena. Seating is available on a free, no-ticket-required, first-come, first-served basis. Caltech has offered the Watson Lecture Series since 1922, when it was conceived by the late Caltech physicist Earnest Watson as a way to explain science to the local community.

Caltech Philosopher Wins Lakatos Award

PASADENA, Calif.—Those who think that philosophy is about a bunch of dead guys with names like Plato and Kant and Hume will be surprised to learn that the philosophy of science is active and vibrant these days. What's more, some of the work currently being done in the field is as relevant to our daily concerns as the question of whether a certain new cancer drug is being tested properly in clinical trials.

According to James Woodward, the Koepfli Professor of the Humanities at the California Institute of Technology, some of the most interesting work in contemporary philosophy concerns the underlying logic of causal inference. By definition, the philosophy of science is the study of scientific methodology, but new developments such as biological innovation have kept guys like Woodward busy of late.

For a recent book on the topic of causal explanation, Making Things Happen, Woodward has been named winner of this year's Lakatos Award by the London School of Economics and Political Science. The Lakatos Award is given annually for an outstanding contribution to the philosophy of science. Woodward will travel to London in May to receive the £10,000 award and deliver a lecture.

Woodward advocates what he calls an interventionist conception of causation, according to which our interest in finding causal explanations is closely related to our interest in changing or manipulating nature.

For example, research in biology and biomedicine has become more inclined toward deliberate intervention to promote better causal understanding of the rules of nature. Whereas biologists once devoted much of their resources toward observation and classification, they may now manipulate genes in order to understand an organism, its development, and its molecular composition.

Central to constructing causal explanations is providing answers to what Woodward calls "what-if-things-had-been-different questions." Explanations of this type result in "counterfactual" dependencies, and these must be understood appropriately, he writes.

As an end result, "causal and explanatory claims are informed by our interest as practical agents in changing the world," Woodward adds.

Causal explanation is not only important in scientific life, but in our everyday interactions as well. We have a vested interest in knowing whether a bogus e-mail file will cause our computer to crash, but we also want to know whether a specific drug can treat heart disease.

The reason the latter is of concern to the philosophy of science, Woodward says, is that it's necessary to know precisely what is involved in clinical trials. "You want to determine whether this new medicine improves the prospects of people with heart disease, but if you set up an experiment and the test subjects are, on balance, healthy, then you're going to be led to a mistake in your inference about whether the medicine is effective or not."

While this conundrum has been known for decades as the "problem of confounding," Woodward says that it exemplifies the kind of situation that philosophers a few hundred years ago didn't understand. This is because the preferred procedure, in the previous example, is to employ probability and statistics in randomly assigning people to the control group and the group that gets the medicine.

"You then hope that all of the other things that could cause discrepancies are approximately equal," he says.

Another especially active endeavor in Woodward's field is the creation of automated data-mining techniques. This work involves looking at statistical data in ways to properly infer causal relationships.

The Lakatos Award is made possible by a generous endowment from the Latsis Foundation, and is given in memory of the former London School of Economics and Political Science professor Imre Lakatos.

Revealing Book from Caltech Professor Chronicles Jewish Past

PASADENA, Calif.-"[Cousin] Bobby's arrests . . . angered rather than surprised my relatives. In half a century of racketeering, he was the first member of the family to be arrested, let alone convicted. The first, that is, if you excluded Tilly's husband, sweet-talking Uncle Charlie, who did two years for setting fire to his failing upholstery business in order to collect the insurance . . ."

The preceding excerpt is from award-winning author and historian Robert A. Rosenstone's book The Man Who Swam into History: The (Mostly) True Story of My Jewish Family (University of Texas Press, Austin, 2005).

On February 13 at 7 p.m., at Vroman's Bookstore, Rosenstone, a professor of history at the California Institute of Technology, will do a reading from his book, which chronicles a Jewish family's passage from Romania to America.

Although the book describes the Jewish Diaspora in the 20th century, it is much more than the typical "poor immigrant, coming to America, rags to riches" saga. From Communists to racketeers and con men, mistresses to mysterious murders, The Man Who Swam into History weaves an intriguing--sometimes humorous--tale of one Jewish family's migration to America, spun from a fascinating collection of memoirs, and as the subtitle says, "mostly true" stories.

Rosenstone's unique literary style ingeniously blends biographical fact and fiction, revealing the true characters of his loving--sometimes eccentric--family and their gossip, quarrels, shared dreams, and fears. Rather than a linear chronology, Rosenstone combines the memoirs, anecdotes, and embellished tales resurrected from the lives of three familial generations. And he takes the "fictional liberty" to sometimes reconstruct the past, when the facts are vague or sketchy. The book sometimes even questions the truth of its own assertions.

For example, Rosenstone says, "Since I was a small child, I always heard the heroic tales of my brave and noble grandfather, Chaim Baer, who escaped from Russia by swimming the Pruth River to Romania . . . It wasn't until I was an adult that I learned that almost every Romanian Jew has a brave and heroic grandfather who swam the Pruth River to escape Russia . . . "

Rosenstone goes on to say, "I grew up believing that my father was a successful businessman. I did not find out until I was 19 or 20 years old, (from older cousins--and my mother confirmed it) that my father's real occupation was numbers running and racketeering." Rosenstone continues, "Families are a 'field of stories.' They share stories, recollections, and family folklore--not just the factual truth. These shared memories are what bind and hold a family together."

Alan Cheuse, a writer and a commentator for National Public Radio, says of Rosenstone and his latest book, "One of our most imaginative living historians takes us into the midst of his own past and makes us part of his family, even as he becomes part of our own. This book stands as a triumph of new scholarship and narrative."

Rosenstone's works have been translated into French, German, Spanish, Italian, Portuguese, Japanese, Korean, and Hungarian. He has won four fellowships from the National Endowment for the Humanities and three Fulbright fellowships. His previous works include Romantic Revolutionary: A Biography of John Reed, which was used as the basis of the film Reds, a winner of several Oscars; Crusade of the Left; Mirror in the Shrine; Visions of the Past: The Challenge of Film to Our Idea of History; and King of Odessa, a historical novel based on the life of Russian writer Isaac Babel.

Experimental Economists Find Brain Regions That Govern Fear of the Economic Unknown

PASADENA, Calif.—Do you have second thoughts when ordering a strange-sounding dish at an exotic restaurant? Afraid you'll get fricasseed eye of newt, or something even worse? If you do, it's because certain neurons in the brain are saying that the potential reward for the risk is unknown. These regions of the brain have now been pinpointed by experimental economists at the California Institute of Technology and the University of Iowa College of Medicine.

In the December 9 issue of the journal Science, Caltech's Axline Professor of Business Economics Colin Camerer and his colleagues report on a series of experiments involving Caltech student volunteers and patients with specific types of brain damage at the University of Iowa. The object of the experiments was to see how the brain responded to degrees of economic uncertainty by having the test subjects make wagers while being scanned by a functional magnetic resonance imager (fMRI).

The results show that there is a definite difference in the brain when the wagers add a degree of ambiguity to the risk. In cases where the game involves a simple wager in which the chance of getting a payoff is very clearly known, the dorsal striatum tends to light up. But in a nearly identical game in which the chances of winning are unknown, the more emotional parts of the brain known as the amygdala and orbitofrontal cortex (OFC) are involved.

According to Camerer, this is a clear advancement in understanding the neural basis of economic decision making. Much is already known about how people deal with risk from the standpoint of social sciences and behavioral ecology, but greater understanding of how the brain structures are involved provides new insights on how certain behaviors are connected.

"The amygdala has been hypothesized as a generalized vigilance module in the brain," he explains. "We know, for example, that anyone with damage to the amygdala cannot pick up certain facial cues that normally allow humans to know whether they should trust someone else."

Problems with the amygdala are also known to be associated with autism, a brain disorder that causes sufferers to have trouble recognizing emotions in other people's faces. One of the authors of the paper, Ralph Adolphs, the Bren Professor of Psychology and Neuroscience at Caltech, has done extensive work in this area.

As for the OFC, the structure is associated with the integration of emotional and cognitive input. Therefore the OFC and amygdala presumably work together when a person is confronted with a wager for which the odds are unknown-the amygdala sends a "caution" message and the OFC processes the message.

The researchers set up the experiments so that the "risk" games and "ambiguity" games looked similar, to control for activity in the visual system so they could focus only on differences in decision making. In the "risk" games, each test subject was provided an opportunity to either choose a certain amount, like $3, or else choose a card that could be either red or blue. If the card was red, the test subject got $10, but if it came up blue, the test subject got nothing for that particular card.

In the risk games, each test subject was informed that the chance of drawing a red card was 50 percent, that there would be 10 of each color out of the total of 20 cards. Subjects made a series of 24 choices, with different sums of money at risk and different numbers of cards. In the ambiguity games, however, each test subject was told that the deck contained 20 cards, but was told nothing about how many were red and how many were blue.

As predicted from past experiments in which this type of risk was observed in test subjects, the researchers knew that the Caltech subjects with no brain damage would be more likely to draw cards in the risk game than in the ambiguity game, because people dislike betting when they do not know the odds. They were more likely to take sure amounts, which meant that their fear cost them money in expected value terms.

The patients at the University of Iowa Medical School, on the other hand, who had lesions to the OFC, played the game entirely differently. On average, these subjects with damage to the OFC were much more tolerant of risk and ambiguity.

Camerer says that the result with the brain-damaged test subjects fits well with the observation that many have suffered in their personal lives due to reckless financial decisions.

The research also addressed the intensity of the response in the brain as it correlates with degrees of risk. The results for the Caltech students showed more intense activity in the amygdala and OFC when the chance of winning is ambiguous, but there would be no such difference in patients with damage to those areas.

In sum, the results provide an important neurological understanding of how we humans handle risk in the real world, Camerer says.

"If you think about it, how often do you know the probability of success? Probably, the situation we modeled with the risk game is more the exception than the rule," he says. "In most situations, I think you are confronted with a risky choice in which you have little idea of the chances of different payoffs."

Does the study have any applications for society? Camerer says that our knowing what is happening at the most microscopic level in the neurons of the brain could lead to better understanding of bigger social effects. For example, a fear of the economic unknown will also create a strong preference for the familiar. In every country in the world, investors hold too many stocks they are familiar with, from their own countries, and do not diversify their stock holdings enough by buying ambiguous foreign stocks. The opposite of fear of the economic unknown may be driving entrepreneurs, who often thrive under uncertainty.

"It could be that aversion to ambiguity is like a primitive freezing response that we've had for millions of years," Camerer says. "In this case, it would be an economic freezing response."

The study is titled "Neural Systems Responding to Degrees of Uncertainty in Human Decision Making."

In addition to Camerer and Adolphs, the other authors are Ming Hsu and Meghana Bhatt, both graduate students in economics at Caltech; and Daniel Tranel of the University of Iowa College of Medicine.

Science Historian Named Caltech/Huntington Professor

PASADENA, Calif.- A historian with interests as wide-ranging as entomology and Greek astronomy has become the first-ever Eleanor Searle Visiting Professor in the History of Science, a newly established joint program between the California Institute of Technology and the Huntington Library, Art Collections, and Botanical Gardens.

Ido Yavetz, assistant professor at The Cohn Institute for History of Science at Tel Aviv University in Israel, arrived in Pasadena this fall and will remain for the academic year. Yavetz specializes in history of classical electromagnetic field theory, history of electrical technology in the late 19th and early 20th centuries, history of entomology in the 19th century, and history of early Greek astronomy.

Through the scholar program, he will teach two courses at Caltech and conduct research at The Huntington, in the area of ancient Greek astronomy. Yavetz earned his bachelor's degree and did post-graduate work in physics while earning a master's and PhD in history of science, all at Tel Aviv University. He was a visiting professor at Caltech in 1999-2000.

Each year the scholar will be chosen by the Caltech faculty with the advice and consent of the director of research at The Huntington.

The goal of the scholar program is to bring visiting faculty to Caltech with a superb track record in teaching, who can inspire students to think about the role creativity plays in the scientific process. A different perspective on the challenges that Copernicus, Galileo, Da Vinci, Newton, and Einstein confronted in their work and how they overcame them could be enlightening to today's scientists. Simultaneously, faculty members have the opportunity to exercise their own creative instincts in conducting research at The Huntington to help inform their teaching.

"The Huntington and Caltech were born at roughly the same time as research institutes and have remained close ever since," says Robert C. Ritchie, W.M. Keck Director of Research at The Huntington. "This gift furthers our joint goals in the history of science and honors a great scholar who enriched the intellectual life of Caltech and The Huntington."

The program is named for Eleanor Searle, the first woman to hold a named professorship at Caltech. She was a world famous medieval historian, a popular teacher, and respected colleague during her time at Caltech, 1979 to 1993. She continued to conduct research at The Huntington until her death in 1999. The author of four books in medieval history that are still widely cited, her students and fellow faculty members were saddened when glaucoma cut short her career and forced her to retire early.

An anonymous local couple is funding $100,000 in annual program costs during their lifetimes. They have established a $2 million charitable remainder trust to eventually fund the Searle Visiting Professors Endowment and provide the program's permanent source of support.

ABOUT CALTECH: With an outstanding faculty, including five Nobel laureates, and such off-campus facilities as the Jet Propulsion Laboratory, Palomar Observatory, and the W.M. Keck Observatory, Caltech is one of the world's leading research centers. The Institute also conducts instruction in science and engineering for a student body of approximately 900 undergraduates and 1,200 graduate students who maintain a high level of scholarship and intellectual achievement. U.S. News & World Report continues to rank Caltech's undergraduate and graduate programs among the nation's best.

ABOUT THE HUNTINGTON: The Huntington Library, Art Collections, and Botanical Gardens is a collections-based research and educational institution serving scholars and the general public. More information can be found on the Web at www.huntington.org.

Voting Experts Say Californians Should Make Sure Their November 8 Votes Are Counted

PASADENA, Calif.—The November 8 special election will allow California voters to decide on a number of initiatives rather than elect new people to statewide offices. But even though votes for a candidate will not be counted this time, the possibility of "lost" votes still exists, says an authority on voting at the California Institute of Technology.

"The experiences of recent elections have shown us all that we should continue expending some effort to make sure our votes count," says Michael Alvarez, a professor of political science at Caltech and codirector of the Caltech-MIT Voting Technology Project. The VTP researchers determined after the 2000 presidential election that up to six million votes had been lost.

Alvarez and his colleagues, who have devised seven steps for voters to take to ensure that their votes are counted, say these steps will be effective for the upcoming initiative election.

The announcement of the seven steps is being made as part of the ongoing voting project, which was initiated in December 2000 by Caltech president David Baltimore and former MIT president Charles Vest following the election debacle the previous month. The Caltech-MIT group, composed of both political scientists and engineers, is charged with evaluating the current state of reliability and uniformity of U.S. voting systems, establishing uniform attributes and quantitative guidelines for performance and reliability of voting systems, and proposing specific uniform guidelines and requirements for reliable voting systems.

The seven steps the group recommends are as follows:

1. Check that you are correctly registered to vote if you have recently moved, changed your name, or recently have filled out a voter registration form. If you are unable to check this on the Internet, call your local election office to make sure you are registered, that you are on your precinct's list of registered voters, and whether you need to bring a form of identification with you in order to vote. If you have any doubt, you should call as soon as possible. The telephone number for your local election office is available from directory assistance.

2. If for any reason there is a chance you cannot get to your local polling place on November 8, request an absentee ballot today or check with your county election official to see if early voting is being offered in your area.

3. Check your ballot. If you vote by mail, make sure to check for errors on your ballot before putting it into the envelope. Also, make certain you provide all required information, (especially your signature) on the envelope, and return your ballot early enough to ensure that your county election official receives it before polls close at 8 p.m. on November 8. You can return it by mailing it to your county election official, by dropping it off at any polling place or the county election office on election day, or by authorizing a legally allowed third person to return it for you.

4. Get a sample ballot from your local elections office if one hasn't been mailed to you, read it carefully, and bring it with you to vote. If you have received a sample ballot in the mail, this is a good time to make sure that your name and address are correct and that you know the location of your polling place. Your sample ballot contains a wealth of information and also provides a convenient way to double-check your registration information as well as consider your choices on the initiatives, which are complicated and require some study. You can mark your choices in your sample ballot and use it for reference when voting.

5. If your name does not appear on the list of registered voters at your polling place, and you believe you are registered to vote and are in the right precinct, you have the right to cast a provisional ballot.

6. Get informed. Read your voter information booklet and sample ballot. If you did not receive one or both, contact your election office immediately, as this might indicate a problem with your registration status.

7. Contact your election office with questions or for help. If you have easy Internet access, you can find the telephone number of your county election office at http://www.ss.ca.gov/elections/elections_d.htm. Or you can call the California Secretary of State's office at 1-800-345-VOTE for information on how to contact your county election office.
