Design for Cognitive Bias: Audiobook Available Now!

Our users have biases and so do we. My best-selling book, Design for Cognitive Bias, explores how design and content strategy can help keep bias at bay—or use it for good.

This essential book will fundamentally change the way you think about design—and about your own mind.

Let’s Chat

Need a speaker for your next event? I’ve given standing-room-only presentations at TEDNYC, SXSW, Confab, LavaCon, UX Copenhagen, Artifact, and the Wharton Web Conference (and my webinar game is pretty tight).

My talks focus on how decision-makers can design can understand bias (and use it for good), how to help people talk to each other more clearly and treat each other more equitably, and how to advocate for change in your organization. I offer an inclusive design workshop for a deeper dive here. My newest talk offers a blunt look at how pursuing engagement for its own sake can be harmful and offers more human approaches for our work in tech.

At our Design Summit, David’s presentation not only introduced innovative concepts that challenged conventional thinking but also ignited a collective commitment toward crafting solutions that address the diverse needs of users. His understanding of cognitive biases and their impact on the design process was both inspiring and informative.
