Open, Sesame*

The NPR radio program On the Media had an interesting story last week. It was about neuropsychologist Vaughan Bell’s article in Slate.com concerning alleged negative effects of technology on our brains and behavior. Bell says that these popular media reports are based mostly on hearsay rather than on evidence from actual research. He thinks that it is a bad idea to reach conclusions about this issue based on anecdotal or scant information.

Pardon my “I told you so” attitude, but Bell does underscore the message I harp on in my February 16 and January 5 posts. Still, I don’t agree with his more general conclusion, that technology has negligible effects on our lives. Of course, Bell doesn’t say exactly that. He is talking about demonstrable effects of technology (defined as video game and Internet use) on our neurons and behavior. Besides, Bell’s conclusion would not apply if we had research questions about possible effects of technology from sociological, political, cultural or economic perspectives.

Speaking of sociological impacts of technology, I want to recount a naturalistic participant-observer field study I accidentally conducted on this very topic! Well…okay, I admit this wasn’t exactly field research. It is just a story I offer because I think it is interesting and fairly revealing.   [Read more...]

Navigating with Fragmentary Information

I have implied this in other entries in this blog, but I might as well say it outright: The library and information science profession needs to come to terms with the issue of standards for (i.e., rules of) evidence for performance, statistical, and advocacy research data. There, now I’ve said it.

I recently read the short and enjoyable book Graphic Discovery: A Trout in the Milk and Other Visual Adventures by statistician Howard Wainer (Princeton, NJ: Princeton University Press, 2005). The subtitle of the book comes from something Henry David Thoreau wrote. During a dairy strike in 1850 in New England people began to suspect that dairy owners were watering down the milk supply. This led Thoreau to write in his journal, “Sometimes circumstantial evidence can be quite convincing; like when you find a trout in the milk” (quoted in Wainer, p. 81).

Wainer’s main point, one certainly made also by others like William Cleveland and Edward Tufte, is that well designed graphical representations are invaluable for exploring and understanding data. Graphical representation of data can lead to revelations about data and the underlying phenomena they describe that would otherwise be missed.   [Read more...]
