Stephens-Davidowitz writes about Jeremy Ginsberg, who tracked disease statistics using big data. Google data trends might also shed insight on the rate of infectious diseases, as opposed to data from the Center for Disease Control. How can we use big data appropriately? We could calculate the prevailing rate of unemployment using Google queries instead of Bureau of Labor Statistics reports, for example. Not all data can help make predictions or reveal trends. The author notes that data science isn't just about how much data is gathered or obtained, but also about how appropriately it gets used. This means the information we get from big data doesn’t lie, unlike information from other surveys and studies. Big Data Doesn’t Lie People enter their queries into search engines with no one watching. Our predictions and gut feelings can only be proven or disproven when we use historical data correctly. However, intuition is not the same as data science. Many people use the intuitive concepts of data science daily without even realizing it. What is “Big Data?” “Big data” refers to large amounts of data that can only be understood using computational power. He starts by introducing us to big data, and to the big ideas it can support. PART I: Stephens-Davidowitz analyzes patterns and trends to help show people’s preferences and habits when using search engines. In a useful read full of memorable take-homes, he draws insights from big data relating to various spheres of our lives. Stephens-Davidowitz explores big data trends that show that we often lie, or at least avoid telling the full story, in our day-to-day lives (especially when no one is looking). He also sheds light on the fact that we actually share more private information with search engines than with our colleagues. In this book that’s been called “ Freakonomics on steroids,” the author tells us why everybody lies, exploring topics ranging from elections to sex. Seth Stephens-Davidowitz, an ex-Google data scientist and op-ed writer for the New York Times and The Guardian, gives insight into how we can use data collected by websites and search engines in this fascinating dive into big data and analytics.
