Ronald Bailey Reviews The Half-Life of Facts

In the modern world facts change all of the time according to Samuel Arbesman, author of The Half-Life of Facts: Why Everything We Know Has an Expiration Date. The amount of scientific data doubles every 15 years and often ends up overturning former dogmas. And since fact-making is speeding up, Arbesman worries that most of us don't keep up-to-date and base our decisions on facts we dimly remember from school and university classes that turn out to be wrong. Reason Science Correspondent Ronald Bailey thinks our only hope to stay current will be constant updates through direct brain/computer telecommunication links.
