The individualized newspaper (aka "Daily Me") that caters to each reader's personal preferences is coming soon. The Google News approach of allowing each reader to customize the display by selecting topics or phrases is not adequate for a newspaper's long term survival.

Until the 1940s economists thought that the only way to determine a person's precise preference map was to ask them their preferences. This proved to produce a very imprecise and inaccurate preference map. When his Harvard economics professor explained that this was unfortunately the only viable approach, graduate student Paul Samuelson claimed to have a better way. He called his new method "revealed preference." Samuelson went on to become an MIT professor and Nobel Prize laureate in economics.

Proving your professor wrong has become a time honored tradition, but proving Google News wrong may take a bit more explaining. The key to the success of revealed preference is that it focuses on what a person actually does and not on what they say they want or expect to do. If you ask me what I like to do, I would tell you that I like snow skiing in the winter and water skiing in the summer. If you observe my behavior, I hardly ever do either. Cake and ice cream sound great, but I'd be a lot heavier if I went that route.

Behavioral targeting is essential to giving readers what they really want. As an economist I don't care what you say, I just want to see what you actually purchase with your money. With online news time is money. You reveal your news preferences when you reveal what you spend your time reading.

It's not that Google News is actually totally wrong but that its approach up to now is just totally inadequate. A much better approach is Amazon's collaborative filter method. Following Amazon's approach to book recommendations, newspapers could suggest news and commentary by first observing what a particular reader rates highly. Then suggest other news and commentary based on what other readers with similar tastes have enjoyed.

Neflix has used this approach to offering its customers movie recommendations. In the fall of 2006 Netflix CEO Reed Hastings offered a million dollars to anyone who could improve Netflix's recommendation system by 10 percent. On Monday September 21, 2009 a group of 7 scientists and engineers won the prize in a competition with 51,000 contestants from 186 countries.

Of course Google's famous search technology uses some ideas along this line. However, Google has yet to apply these methods to create an individualized "Daily Me" display of news and commentary in Google News. Hopefully they are already planning to apply these methods in the future.

In the long run online newspapers will not be profitable if they don't understand the difference between what readers say they want and what they really want. Asking a reader's preferences may be a good first step, but it is not sufficient. A newspaper that is serious about surviving online must go further and observe where the readers really spend their time, and ultimately, their online money. Newspapers that ignore the need for online behavioral targeting will themselves ultimately be ignored.

There is a dark side to all this. Traditional newspapers expose a reader to a wide variety of news and commentary. Readers who focus on their own narrow interests may become uninformed voters and poor citizens. If readers concentrate their interests and only see and read what they really want, they may become like the professor becoming increasingly specialized in his or her field who learns more and more about less and less until they know everything about nothing.

After writing this I discovered that there is already a "Daily Me" located at dailyme.com. See comment from dailyme below.
