For years, people have been observing that the wonderful surfeit of information sources available through the Web can result, paradoxically, in a narrowing of our perspectives. In the political realm, for example, liberals can now get all their news from liberal sites, and conservatives from conservative sites.

The Boston Globe has a good review today of a paper published in Science some months ago reporting that groupthink is affecting even scientific research publications — the lists of cited papers are becoming more homogeneous, not more varied, as the information sources diversify.

And so it is with scientific papers — with most available online, a smaller number are cited more often than in the past.
