Privacy on the Web is a constant issue for public discussion—and Congress is always considering more regulations on the use of information about people's habits, interests or preferences on the Internet. Unfortunately, these discussions lead to many misconceptions. Here are 10 of the most important:

1) Privacy is free. Many privacy advocates believe it is a free lunch—that is, consumers can obtain more privacy without giving up anything. Not so. There is a strong trade-off between privacy and information: The more privacy consumers have, the less information is available for use in the economy. Since information helps markets work better, the cost of privacy is less efficient markets.

2) If there are costs of privacy, they are borne by companies. Many who do admit that privacy regulations restricting the use of information about consumers have costs believe they are born entirely by firms. Yet consumers get tremendous benefits from the use of information.

Think of all the free stuff on the Web: newspapers, search engines, stock prices, sports scores, maps and much more. Google alone lists more than 50 free services—all ultimately funded by targeted advertising based on the use of information. If revenues from advertising are reduced or if costs increase, then fewer such services will be provided.
