Recently, following an assignment that required AI use, a student asked me whether it was true that every question she asks a chatbot uses up a whole bottle of water. Like so much information today, she received this claim via a social media video. The video apparently cited a newspaper article which cited a real study. She had also heard people all around her, both in real life and online, talking about the huge amounts of water these systems use. Of course, she could get more information by searching online, asking a chatbot, asking friends and teachers or listening to the many podcasts discussing the issue. In other words, my student has no shortage of information, but what she doesn’t have is a solid way to judge its accuracy, how much confidence a given claim deserves, nor which sources can be trusted. Though many students are now “digital natives,” in the sense that they have grown up with smartphones and tablets, it has been my experience that they are not skilled in navigating the bewildering and fast growing world of information available to us all.
At the same time, there seems to be a deepening distrust in institutions and authorities as well as widespread disagreement on the factual basis of some of the most important issues in the public discourse. More than ever, I hear from students who don’t see the value of a “well-rounded” education nor in spending time in courses that aren’t directly tied to their career paths. Artificial intelligence has made the question of what an education offers even more urgent, as we now have machines that deliver confident answers on almost any subject (some right and some wrong) and produce content far faster than people can check it. Taken together, these observations have forced me to think about what my role in this educational process is really for. Particularly when it comes to teaching non-science majors, I think what science has to offer are ways of thinking that can be applied across many domains. The framework key to it all is something we now describe with the shorthand “scientific method”: how human beings have learned to test claims about the world and preserve what survives rigorous testing. Of course, most science courses already cover the scientific method: ask a question, form a hypothesis, test it, analyze the results, and draw a conclusion. But the treatment is often superficial, students don’t arrive in my classroom with an intuitive understanding of what it really means, and I think we leave out much of what makes the process work. This essay is my attempt to lay out what the five steps leave out, using my student’s question as an illustrative example. Read more »

Many of the books that shaped my work as a professor, author, and activist came into my life during my first two years of graduate school (1988-90), the most exciting period of concentrated learning I’ve ever experienced. As I write in my new book, 







The preamble of the US Constitution famously begins with the phrase “We the People”. Who, and how many, constituted this self-identified group? How well founded was this invocation of “We the People”?
