NEW YORK ( TheStreet) -- When push comes to shove, the vast majority of investors -- professional and otherwise -- tend to stick with the herd. As a result, statistics show that the long-term performance of most investors tends to be mediocre at best.Truly independent thinking is a rare commodity on Wall Street and everywhere else. What's more, the explosion of 24-7 media consumption threatens to fuel more groupthink, which can have disastrous results. In contrast, consider the actions of business mogul John Malone and his team at Liberty Media ( LMCA), which launched a surprise effort to buy Barnes & Noble's ( BKS) about a year ago, when the company was being dismissed by many as road kill on the digital media highway. Liberty wound up with preferred stock that's convertible into common shares worth a 16.6% stake in Barnes & Noble. Now consider this week's news that Barnes & Noble's Nook e-reader business will receive hundreds of millions of investment dollars from tech giant Microsoft ( MSFT). This gave new credibility to an effort by the venerable bookstore chain to reinvent itself for the digital age. For investors paying close attention, the news also bolstered the reputation of Malone.
