How Big Data Reveals Who We Really Are: A Review of Everybody Lies

**Disclaimer: This article contains some spoilers.**

Everybody Lies: Big Data, New Data, and What the Internet Can Tell Us About Who We Really Are is a captivating exploration of human behavior and societal trends, written by Seth Stephens-Davidowitz. This New York Times bestseller, published in 2017, offers a fresh perspective on how big data, particularly internet search data, can reveal profound truths about human nature that traditional surveys and studies often miss.

The Power of Big Data

Stephens-Davidowitz, a Harvard-trained economist and former Google data scientist, argues that the vast amount of data generated by our online activities provides unprecedented insights into human psychology and behavior. By the end of an average day in the early twenty-first century, internet searches generate a staggering eight trillion gigabytes of data. This digital goldmine allows researchers to uncover truths about our fears, desires, and behaviors that were previously hidden or misunderstood.

The Honesty of Search Data

One of the key premises of the book is that people are more honest with their search engines than they are with surveys, friends, or even themselves. While we often present a curated version of ourselves to the world, our Google searches reveal our true thoughts and concerns. This "digital truth serum" provides a unique window into the human psyche.

Surprising Revelations

Racism and Politics

Stephens-Davidowitz's analysis of search data revealed uncomfortable truths about racism in America. For example, he found that racist searches were a strong predictor of Donald Trump's performance in the 2016 election, offering insights that traditional polls missed.

Gender and Parenting

The book also explores how big data can reveal hidden biases in parenting. For example, parents are more likely to search for information about a son's intelligence compared to a daughter's, suggesting a subtle gender bias in how we perceive and nurture our children.

Sexuality and Relationships

Everybody Lies delves into sensitive topics like sexuality, revealing surprising patterns in sexual behavior and preferences. The author's analysis of pornography searches provides insights into sexual desires that people are often reluctant to admit in surveys or to their partners.

Methodology and Implications

The World as a Lab

Stephens-Davidowitz demonstrates how the internet has turned the world into a vast laboratory for studying human behavior. By analyzing search trends, social media activity, and other online behaviors, researchers can conduct large-scale "experiments" without the limitations of traditional studies.

Challenging Assumptions

The book challenges many commonly held beliefs about human behavior. For instance, it questions the effectiveness of certain educational interventions and the true impact of role models on career choices. These insights have significant implications for policy-making and social interventions.

Ethical Considerations

While the book celebrates the potential of big data, it also raises important ethical questions. The ability to glean such intimate insights from our online activities raises concerns about privacy and the potential for misuse of this information.

Applications Beyond Social Science

Economics and Business

The insights from big data analysis have profound implications for economics and business. Stephens-Davidowitz explores how these techniques can be used to predict economic trends, consumer behavior, and even stock market movements.

Health and Well-being

The book also discusses how search data can provide early warning signs for health issues, both physical and mental. For example, certain search patterns might indicate the onset of depression or other mental health conditions before they're clinically diagnosed.

Critical Reception

Everybody Lies has been widely praised for its innovative approach and engaging writing style. It has been compared to works like "Freakonomics" and "The Signal and the Noise" for its ability to blend data analysis with storytelling. However, some critics have raised concerns about the potential overreliance on search data and the need for caution in interpreting these results.

The Future of Big Data Research

Stephens-Davidowitz concludes by speculating on the future of big data research. He envisions a world where data science and traditional social sciences work together to provide a more complete understanding of human behavior. This collaboration could lead to more effective policies, better products, and improved social interventions.
