“When reviewing one's portfolio, it is important to be aware of common mental mistakes that may lead to bad decisions. The most powerful is commitment bias, which, as manifested in investing, is the tendency to fall in love with one's stocks.”

“No one would suggest completely ignoring news about your investments. Enron investors, for example, would have been well served to sell once early reports of accounting irregularities surfaced. But the key is to keep news in context and act only if further reflection or study indicates that the core thesis for an investment has changed.”

“But there is something to the fact that we don't see games on the West Coast, or we don't see games on the East Coast, and stuff like that. It's so unfair, because there is a bias that takes place.”

“Merely implying bias due to a judge's ethnic heritage is wrong as a matter of principle and legally illegitimate.”

“Design can overcome our most deeply rooted stranger-danger bias.”
