My summary: Most of the time, journalists report on what the market did. Sometimes it’s the other way around, and markets do what the journalists suggest. Suggest through the use of powerful words. Words that evoke emotion. And more unusually, such market responses tend to be short-lived, clawing back losses (or giving away gains) within a short period of the original article’s appearance.
Interesting. Lakoff and anchoring and framing meets Surowiecki and Wisdom of Crowds? I wonder what would happen if Paul Tetlock ran the same study on blogs, on journalism that is characterised by voice and passion.
