Does the internet make you overconfident? (this post may offend some bloggers)

Dan Klein (from Abigail D.) directs my attention to an interesting paper by Fisher, Goddu, and Keil (pdf):

As the Internet has become a nearly ubiquitous resource for acquiring knowledge about the world, questions have arisen about its potential effects on cognition. Here we show that searching the Internet for explanatory knowledge creates an illusion whereby people mistake access to information for their own personal understanding of the information. Evidence from 9 experiments shows that searching for information online leads to an increase in self-assessed knowledge as people mistakenly think they have more knowledge β€œin the head,” even seeing their own brains as more active as depicted by functional MRI (fMRI) images.

Having done some further search on this topic, using Google, I can assure you that I now have a much better grasp on whether this hypothesis is true or not…
