The Wall Street Journal:

The Wall Street Journal poses an interesting question: If the Internet is so full of snarkiness then why do product reviews usually tend to be positive?

The Journal says 4.3 (out of five) stars is the standard grade a reviewer assigns on the web. But this “grade Inflation” may not be just on the Internet.

Experts say that in general, 85 percent of word-of-mouth recommendations are positive.
