Freakonomics: A Rogue Economist Explores the Hidden Side of Everything

In the early 1990s, America was gripped by fear. Crime rates were skyrocketing, and experts warned of an impending wave of violence led by ruthless teenage "superpredators." Predictions were dire, with grim scenarios outlined by criminologists and even echoed by President Clinton. But then, against all expectations, crime rates began to plummet in the mid-1990s.

This dramatic reversal baffled experts, who scrambled to explain it. Theories ranged from a booming economy to innovative policing strategies, but none of these explanations fully accounted for the steep decline. 

Surprisingly, a significant factor was rooted in a landmark Supreme Court case two decades earlier: Roe v. Wade. The legalization of abortion in 1973 meant that many children who would have been born into adverse environments and potentially turned to crime were never born. This reduction in the pool of potential criminals played a crucial role in the crime drop.

But this wasn’t the only area where conventional wisdom was challenged. Consider real-estate agents. They are perceived as experts who maximize the value of homes for their clients. However, data revealed a different story: agents sold their own homes for higher prices and kept them on the market longer than their clients' homes. The incentive for a quick sale for a small commission often outweighed the effort to get a better deal for the client.

Similarly, in politics, the assumption that money buys elections was debunked. Studies showed that while candidates who spend more usually win, it’s not the money causing the victory. Instead, appealing candidates attract both votes and donations. In fact, increasing a campaign budget had minimal impact on changing the vote share.

These insights illustrate a broader truth: incentives drive behavior, and understanding them can unravel complex societal riddles. From crime rates to real estate to political campaigns, examining the hidden layers of incentives reveals surprising truths about how the world really works.

Hidden Side of Economics

Imagine you're managing a day-care center. Parents should pick up their kids by 4 p.m., but many are late. Economists proposed a solution: fine the tardy parents $3. Surprisingly, late pickups increased. This illustrates the complex nature of incentives.

Incentives are tools that encourage certain behaviors. They can be economic (like fines), social (peer pressure), or moral (personal guilt). But they don't always work as intended. For instance, a fine might replace moral guilt with a small economic cost, leading parents to feel okay about being late.

Incentives play a vital role in various aspects of life, including crime prevention. People generally avoid crime due to economic penalties (like jail time), social consequences (shame), and moral reasons (personal ethics). Creative incentives can reduce crime, such as posting photos of convicted individuals online to shame them.

However, when poorly designed, incentives can lead to cheating, as seen in the Chicago Public Schools. High-stakes testing, intended to improve education, sometimes pressured teachers to cheat by altering students’ test answers. An algorithm exposed this cheating, showing that incentives must be carefully balanced to avoid unintended consequences.

Cheating isn't limited to schools. It's present in sports, like sumo wrestling in Japan, where data suggests some matches are rigged. Wrestlers facing demotion might win suspiciously often against those with nothing to lose, hinting at match-fixing.

Cheating also pervades everyday life. Consider Paul Feldman, who quit his job to deliver bagels on the honor system. He found that smaller offices were more honest than larger ones, and people stole less in good weather or when they liked their job. Interestingly, after 9/11, people’s honesty improved, possibly due to a surge in empathy.

This story shows that while cheating exists, most people act honestly even without surveillance. The challenge lies in designing incentives that encourage good behavior without leading to unintended negative outcomes.

Manipulating Morals: The Intricate Dance of Incentives and Cheating in Society

The Ku Klux Klan, founded by six Confederate soldiers in Tennessee, began as a harmless social club but soon transformed into a terror group aimed at suppressing the newly emancipated slaves. Led by former Confederate generals and supported by plantation owners, the Klan used violence and intimidation to achieve its goals. Although temporarily dismantled by President Ulysses S. Grant, the Klan's ideology persisted through Jim Crow laws and was revived in 1915 by the film "The Birth of a Nation."

The Klan's resurgence in the 1920s saw it expand nationwide, targeting not only blacks but also Catholics, Jews, communists, and other groups. Internal scandals and World War II diminished its influence, but postwar fears led to a brief revival. Atlanta became its new headquarters, but it was also home to Stetson Kennedy, a folklorist determined to expose the Klan's secrets. Using his background, Kennedy infiltrated the Klan, gathering inside information that he later shared with journalists and radio shows like "The Adventures of Superman."

Kennedy's strategy was to turn the Klan's secrecy against itself by making its rituals and codes public, thereby reducing its power. This dissemination of information led to a decline in Klan membership and influence. Kennedy's work highlighted the power of information in dismantling organizations that thrive on secrecy.

This concept of information asymmetry—where one party holds more information than another—extends beyond the Klan to many areas of life, including insurance and real estate. The internet, by democratizing access to information, has significantly reduced these asymmetries. Websites like Quotesmith.com allowed consumers to compare term life insurance rates easily, forcing companies to lower their prices.

Similarly, real estate agents, who once held a significant advantage over home sellers, have seen their influence wane as sellers can now access detailed market data online. This shift underscores how powerful information can be, whether it's used to dismantle a hate group or level the playing field in real estate transactions.

Could Information Asymmetry Be the Key to Dismantling Hate Groups and Revolutionizing Industries?

Drug dealers still live with their moms because, despite popular belief, most don't make much money. To understand this, a deep dive into the economics of drug dealing and societal behaviors is necessary.

Sudhir Venkatesh, a sociology PhD student, decided to study Chicago's poorest neighborhoods. One day, while conducting a survey, he encountered a gang of junior crack dealers in an abandoned housing project. Despite initial hostility, Venkatesh's curiosity led him to embed himself with the gang, gaining rare insight into their operations.

Venkatesh discovered a highly structured organization resembling a corporate hierarchy, with J.T., the gang leader, reporting to a board of directors. The gang's revenue came from drug sales, dues, and extortion, with J.T. earning around $100,000 annually. However, the foot soldiers earned a meager $3.30 per hour, less than minimum wage, and faced high risks, including violence and arrest.

Despite the low pay and dangerous conditions, many young men joined the gang, hoping to rise to the top and earn significant money. This dynamic is similar to other competitive fields like sports or entertainment, where many compete for a few lucrative positions.

Drug dealing became a viable job option for many in impoverished neighborhoods, especially as traditional jobs disappeared. The introduction of crack cocaine, which was cheap and highly addictive, provided gangs with a steady source of income. However, the reality was that most gang members never made it to the top and continued to live with their families due to their low earnings.

The crack epidemic also had a devastating impact on black communities, reversing decades of progress in various societal indicators. Despite the allure of potential riches, the harsh realities of drug dealing meant that for most, it was a path fraught with danger and minimal financial reward.

Crack, Crime, and Capital: The Grim Economics of Drug Dealing in Chicago's Poorest Neighborhoods

In 1966, Romania's Communist dictator Nicolae Ceaușescu outlawed abortion, with the chilling declaration that the fetus belonged to the entire society. His radical policies spiked birth rates but cast a dark shadow on the future of these children, who would later face dismal prospects and an inclination toward criminality.

Fast-forward to the United States in the 1990s: an unexpected plummet in crime rates had experts scrambling for explanations. Some attributed the drop to innovative policing and an increase in the number of officers, others to economic upturns, while a few pointed to tougher gun control laws. But beneath these surface theories lay a deeper, more controversial connection between crime rates and a societal choice made two decades earlier.

In a stunning reversal of Ceaușescu's draconian law, the U.S. Supreme Court's Roe v. Wade decision legalized abortion nationwide in 1973. The ruling not only provided women with reproductive autonomy but also, as data later suggested, led to a reduction in crime. The children who were never born post-Roe were statistically more likely to have grown up in adverse conditions and potentially turn to crime. As these non-existent cohorts reached their prime criminal ages in the '90s, the crime wave surprisingly receded.

This correlation between legalized abortion and a drop in crime, while controversial and morally complex, was supported by patterns in states where abortion was legal before Roe v. Wade. These states saw earlier crime declines than others. Researchers also observed a significant difference in crime reduction between states with higher and lower abortion rates.

But this wasn't the only reason. The crack epidemic's decline, changes in the drug market, and demographic shifts also played roles. The fading crack markets meant less profit and, therefore, less incentive for the violence that once fueled crime statistics.

The story of crime in the '90s is a tapestry woven from various threads, including economics, policy, and the unforeseen ripple effects of personal choices.

Did Legalizing Abortion Contribute to the Dramatic Drop in U.S. Crime Rates in the 90s?

Parenting has been turned into a science, with a plethora of experts offering conflicting advice on every aspect of child-rearing. The "right" way to parent seems to change daily, with opinions flipping on everything from breastfeeding to sleeping positions. In her book, "Raising America", Ann Hulbert explores these contradictions. However, the question remains: how much do parents really matter? 

Research has shown that genes account for about 50% of a child's personality and abilities. The rest, one might assume, comes from nurturing: the parenting tactics, the activities, the environment. But several studies have suggested that even these factors may not have as much impact as we think. For example, the Colorado Adoption Project found little correlation between a child’s personality traits and those of their adoptive parents. 

In the book "The Nurture Assumption", Judith Rich Harris argues that parents don’t have as much impact on a child’s personality as they believe. Instead, she suggests that peer pressure and the child’s own choices play a more significant role. 

Data from the Early Childhood Longitudinal Study (ECLS) has shown that certain factors are strongly correlated with a child's school test scores, such as having highly educated parents, parents with high socioeconomic status, and many books in the home. Conversely, other factors, such as attending Head Start program, frequently watching television, or having parents who read to them daily, showed no correlation. 

Interestingly, the factors that correlated with high test scores were largely inherent traits of the parents (who they are), rather than actions they took (what they do). This suggests that while parents undoubtedly matter, parenting techniques may not be as critical as one might think. Instead, a child's success may be more strongly influenced by the parents' own characteristics and socioeconomic circumstances. 

In the end, perhaps the most effective parenting strategy is simply to be the kind of person you want your child to become. After all, children learn more from what they see than from what they are told.

Parenting Paradox: The Less Understood Influence of Genes and Socioeconomic Status on Child Development

How much does a name influence a person's life trajectory? For example, Robert Lane, a New Yorker, named his sons Winner and Loser. Defying expectations, Loser became a successful police sergeant while Winner accumulated a lengthy criminal record. This illustrates that a name, though symbolic and influential in parental expectations, doesn't determine destiny. 

Roland G. Fryer Jr., a black economist, studied the impact of distinctively black names on economic disparity. His research showed that although individuals with distinctively black names do have worse life outcomes on average, the name is not the cause but an indicator of their socioeconomic background. In other words, a DeShawn is likely to face challenges because of the economic circumstances he was born into, not because his name is DeShawn.

Baby-naming trends can also provide insights into cultural shifts and parental ambitions. For instance, names that were once popular among high-income, highly educated parents often trickle down the socioeconomic ladder, prompting higher-end parents to abandon them for fresh, less common names. Celebrities, contrary to popular belief, have a minimal effect on baby names. Instead, it's the families with bigger houses and newer cars that often set the naming trends.

So, while a name might reflect parental expectations or socioeconomic background, it doesn't necessarily shape a person's life. After all, as the story of Winner and Loser Lane proves, destiny is not in a name.

Can Your Name Really Dictate Your Destiny?

In the early '90s, America was terrified of a predicted surge in violent crime led by teenage 'superpredators'. However, crime rates began to decline drastically in the mid-'90s, leaving experts perplexed. A significant contributing factor to this drop was found to be the Roe v. Wade Supreme Court case, which legalized abortion in 1973. This led to a decrease in the number of children born into adverse circumstances, thus reducing the pool of potential criminals.

The conventional thinking that real estate agents maximize the value of homes for their clients was debunked when it was found that agents sell their own homes at higher prices and keep them on the market longer than their clients' homes. In politics, the belief that money buys elections was discredited. While candidates who spend more often win, it's not the money that leads to victory but the candidate's appeal which attracts both votes and donations.

Incentives play a critical role in various aspects of life, including crime prevention. They can be economic, social, or moral, but they don't always work as intended. Poorly designed incentives can lead to cheating, as seen in the Chicago Public Schools where high-stakes testing led some teachers to alter students' test answers.

The Ku Klux Klan, which began as a harmless social club, transformed into a terror group aimed at suppressing newly emancipated slaves. Despite being temporarily dismantled, the Klan's ideology persisted. However, the Klan's power was considerably reduced when its secrets were exposed by Stetson Kennedy, demonstrating the importance of information in dismantling organizations that thrive on secrecy.

Next, despite the popular belief, most drug dealers don't make much money. Many young men join gangs hoping to rise to the top and earn significant money, but most never make it and continue to live with their families due to their low earnings. Drug dealing became a viable job option in impoverished neighborhoods, especially with the introduction of crack cocaine.

Research has shown that genes account for about 50% of a child's personality and abilities. Contrarily, several studies have suggested that factors such as parenting tactics, activities, and the environment may not have as much impact as traditionally believed. Instead, a child's success may be more influenced by the parents' characteristics and socioeconomic circumstances.

Lastly, a person's name doesn't determine their destiny. While a name might reflect parental expectations or socioeconomic background, it doesn't necessarily shape a person's life. Baby-naming trends can provide insights into cultural shifts and parental ambitions, but it's the families with bigger houses and newer cars that often set the naming trends.
