"Technology steers what 2 billion people are thinking and believing every day. It's possibly the largest source of influence over 2 billion people's thoughts that has ever been created. Religions and governments don't have that much influence over people's daily thoughts."

"With our Paleolithic instincts, we're simply unable to resist technology's gifts. But this doesn't just compromise our privacy. It also compromises our ability to take collective action."

"Ergonomics is about designing for failure modes and extremes: how things break under repetition, stress or other limits. And the goal of ergonomic designis to create an alignment between the user's limits, the thing you're designing, and how people will ideally use that thing."

"For every design goal you have, you have to have a corresponding measurement to know how you're doing - a way of measuring success."

"I noticed when I was at Stanford, there was a class called the persuasive technology design class, and it was a whole lab at Stanford that teaches students how to apply persuasive psychology principles into technology to persuade people to use products in a certain way."

"I was a design ethicist at Google, where I studied how do you ethically steer people's thoughts? Because what we don't talk about is how the handful of people working at a handful of technology companies through their choices will steer what a billion people are thinking today."

"I'm an expert on how technology hijacks our psychological vulnerabilities. That's why I spent the last three years as a Design Ethicist at Google caring about how to design things in a way that defends a billion people's minds from getting hijacked."

"We want to have a relationship with technology that gives us back choice about how we spend time with it, and we're going to need help from designers, because knowing this stuff doesn't help. We're going to need design help."
