In April 1999, when I was on a lecture tour for my book Why People Believe Weird Things, the psychologist Robert Sternberg attended my presentation at Yale University. His response to the lecture was both enlightening and troubling. It is certainly entertaining to hear about other people’s weird beliefs, Sternberg reflected, because we are confident that we would never be so foolish. But why do smart people fall for such things? Sternberg’s challenge led to a second edition of my book, with a new chapter expounding on my answer to his question: Smart people believe weird things because they are skilled at defending beliefs they arrived at for non-smart reasons.

In science there is arguably no more suppositional formula than that proposed in 1961 by radio astronomer Frank Drake for estimating the number of technological civilizations that reside in our galaxy: N = R fp ne fl fi fc L

In this equation, N is the number of communicative civilizations, R is the rate of formation of suitable stars, fp is the fraction of those stars with planets, ne is the number of Earth-like planets per solar system, fl is the fraction of planets with life, fi is the fraction of planets with intelligent life, fc is the fraction of planets with communicating technology, and L is the lifetime of communicating civilizations.

There is no more contentious subject in science today than evolution. This fact was brought to light for me in the overwhelming response to my February column on evolution and “intelligent design” creationism. I typically receive about a dozen letters a month, but for this one no less than 134 were submitted (117 men, four women and 13 whose identity was not revealed). I found reading the critical letters mildly disconcerting until I hit on the idea that these are a form of data to be mined for additional information on what people believe and why. Conducting a content analysis of all 134 letters, I discovered patterns within the cacophonous chaos. First I read them quickly and then separated them into about two dozen one-line categories that summed up the reader’s main point. I next condensed these into six taxonomic classes and reread all the letters carefully, placing each into one or more of the six (for a total of 163). (continue reading…)

In 1998 God appeared at Caltech.

More precisely, the scientific equivalent of the deity, in the form of Stephen W. Hawking, delivered a public lecture via his now familiar voice synthesizer. The 1,100-seat auditorium was filled; an additional 400 viewed a video feed in another hall, and hundreds more squatted on the lawn and listened to theater speakers broadcasting this scientific saint’s epistle to the apostles. The lecture was slated for 8 P.M. By three o’clock a line began to snake around the grassy quad adjoining the hall. By five, hundreds of scientists flipped Frisbees and chatted with students from Caltech and other universities. (continue reading…)

In a 1987 lecture entitled “The Burden of Skepticism,” astronomer Carl Sagan succinctly summarized the delicate compromise between tradition and change: (continue reading…)
