"Everybody Lies" by Seth Stephens-Davidowitz, an economist who utilizes large datasets, such as Google searches and Facebook "likes," to understand human behavior and reveal truths often obscured by conventional research methods. The book explores topics like racism, sexuality, child abuse, and the effectiveness of advertising, demonstrating how digital data can offer unique insights into human behavior and potentially change how we view the world. Stephens-Davidowitz highlights both the power and limitations of big data, arguing that while it can provide valuable information, it's crucial to be aware of potential biases and use the data responsibly.
