"How can any passionate individual swing their strong opinions in hours"

Umm, most smart, passionate people can swing their strong opinions within minutes, when presented with the appropriate data. George Soros is legendary for this; he's been known to back out of billion dollar investments the next day. Most good managers are like this too.

The crucial part is data, and how they evaluate that data. And not having read the blog post, I can't say whether Warrior's thought process makes sense. But I really hate the idea that "Passionate people cling to their ideas at all costs" - that's responsible for most of the failures and wasted effort in the world today.
