In a similar vein, the skills that are needed to evaluate the technical material on the Internet are not themselves contained on the Internet. For example, a student does not become a scientist by surfing. A medical student does not learn how to become a doctor by surfing. They may occasionally look up facts and historical data, but the credence they put on the data is based on their own outside training, not on anything intrinsic to the Web pages. In other words, the ability to assign credence is not to be found anywhere on the Internet because the Internet simply contains data.
Evaluation requires rationality, experience and reasoning skills.
These skills evolved in human beings long before the Internet existed. They are quite distinct. And if one looks at the conduct of a person exercising these skills, it's fairly clear that the process of simply reading data on the net does not develop or reinforce those skills. There was a great television show I watched as a youth. Watch Mister Wizard.
