Intentional Misinformation

To continue on the topic of misdiagnosing positions, Sun Tzu makes a central issue of never factoring out the purposeful deception of others. You always have to ask yourself about people's motives for offering the information they do. For example, an very interesting financial blog, carfutia.com, uses the MSM news as a contra-indicator of market direction. When the media's business coverage is primarily negative, the market is going up but when it turns positive, it is time to sell. This is make sense according to Sun Tzu's principles of Reversal, since universal optimism means that there are no new buyers. However, does this system work if the NY Times intentionally decides to NOT to report good economic news during an administration it opposes? There was a stock market correction during the Reagan years despite the MSM's unwillingness to report economic progress during that administration.
