Some gold from Cialdini’s new book Pre-Suasion, para. “What is salient is important”:

[Kahneman] was once asked to specify the one scientific concept that, if appreciated properly, would most improve everyone’s understanding of the world. Although in response he provided a full five-hundred-word essay describing what he called “the focusing illusion,” his answer is neatly summarized in the essay’s title: “Nothing in life is as important as you think it is while you are thinking about it.”

What is salient is indeed important, Cialdini:

As the tenth anniversary of the terrorist attacks of September 11, 2001, approached, 9/11-related media stories peaked in the days immediately surrounding the anniversary date and then dropped off rapidly in the weeks thereafter. Surveys conducted during those times asked citizens to nominate two “especially important” events from the past seventy years. Two weeks prior to the anniversary, before the media blitz began in earnest, about 30 percent of respondents named 9/11. But as the anniversary drew closer, and the media treatment intensified, survey respondents started identifying 9/11 in increasing numbers—to a high of 65 percent. Two weeks later, though, after reportage had died down to earlier levels, once again only about 30 percent of the participants placed it among their two especially important events of the past seventy years. Clearly, the amount of news coverage can make a big difference in the perceived significance of an issue among observers as they are exposed to the coverage

Kahneman’s most important thing is worth repeating for investors:

Nothing in life is as important as you think it is while you are thinking about it.
