Today is the second day of the fifteenth [Workshop on Security and Human Behavior](), hosted by Ross Anderson and Alice Hutchings at the University of Cambridge. After two years of having this conference remotely on Zoom, it's nice to be back together in person. SHB is a small, annual, invitational workshop of people studying various aspects of the human side of security, organized each year by Alessandro Acquisti, Ross Anderson, Alice Hutchings, and myself. The forty or so attendees include psychologists, economists, computer security researchers, sociologists, political scientists, criminologists, neuroscientists, designers, lawyers, philosophers, anthropologists, geographers, business school professors, and a smattering of others. It's not just an interdisciplinary event; most of the people here are individually interdisciplinary. For the past decade and a half, this workshop has been the most intellectually stimulating two days of my professional year. It influences my thinking in different and sometimes surprising ways--and has resulted in some unexpected collaborations. Our goal is always to maximize discussion and interaction. We do that by putting everyone on panels, and limiting talks to six to eight minutes, with the rest of the time for open discussion. Because everyone was not able to attend in person, our panels all include remote participants as well. The hybrid structure is working well, even though our remote participants aren't around for the social program. This year's schedule is [here](). This [page]() lists the participants and includes links to some of their work. As he does every year, Ross Anderson is [liveblogging]() the talks. Here are my posts on the [first](), [second](), [third](), [fourth](), [fifth](), [sixth](), [seventh](), [eighth](), [ninth](), [tenth](), [eleventh](), [twelfth](), [thirteenth](), and [fourteenth]() SHB workshops. Follow those links to find summaries, papers, and occasionally audio/video recordings of the various workshops. Ross also maintains a good webpage of [psychology and security resources]().
