Imagine a world where your brain can be interrogated to learn your political beliefs, thought crimes are punishable by law, and your own feelings can be used against you. Where perfumers create customized fragrances to perfectly suit your emotions, and social media titans bypass your conscious mind to hook you to their products. A world where people who suffer from epilepsy receive alerts moments before a seizure, and the average person can peer into their own mind to eliminate painful memories or cure addictions.

Neuroscience has already made all of the above possible today, and neurotechnology will soon become the universal controller for all of our interactions with technology. This can benefit humanity immensely, but without safeguards, it can severely threaten our fundamental human rights to privacy, freedom of thought, and self-determination. Companies, governments, and militaries are all in: from contemplative neuroscience to consumer-based EEG technology, there have never been more ways to hack and track our brains.

The Battle for Your Brain by Nita A. Farahany dives deeply into the promises and perils of the coming dawn of brain access and alteration. Written by one of the world's foremost experts on neuroscience as it intersects with law and ethics, this highly original book offers a pathway forward to navigate the complex ethical dilemmas that neurotechnology presents, which will fundamentally impact our freedom to understand, shape, and define ourselves.

Our personal data has been used to spy on us, hire and fire us, and sell us stuff we don't need. In Dataclysm, Christian Rudder uses it to show us who we truly are.

For centuries, we've relied on polling or small-scale lab experiments to study human behavior. Today, a new approach is possible. As we live more of our lives online, researchers can finally observe us directly, in vast numbers, and without filters. Data scientists have become the new demographers.

In this daring and original book, Rudder explains how Facebook "likes" can predict, with surprising accuracy, a person's sexual orientation and even intelligence; how attractive women receive exponentially more interview requests; and why you must have haters to be hot. He charts the rise and fall of America's most reviled word through Google Search and examines the new dynamics of collaborative rage on Twitter.

He shows how people express themselves, both privately and publicly. What is the least Asian thing you can say? Do people bathe more in Vermont or New Jersey?

Rudder also traces human migration over time, showing how groups of people move from certain small towns to the same big cities across the globe. And he grapples with the challenge of maintaining privacy in a world where these explorations are possible.

Visually arresting and full of wit and insight, Dataclysm is a new way of seeing ourselves—a brilliant alchemy, in which math is made human and numbers become the narrative of our time.
