It's interesting that he mentions that naming a number first in salary negotiations is to your advantage, when the usual advice is that the first person to name a number loses. If there is really no rebound effect, why don't we hear stories of people asking for outrageous amounts of money, instead of letting the hiring manager name a salary first?
Because most people want to look reasonable at a job interview. However, one thing people miss is that the anchoring can be to any number whatsoever, so you don't even need to talk about what you want per hour. I remember a paper that asked participants to note down the last two digits of their social security, and subjects anchored themselves to that (statistically significantly- one of the authors was Dan Ariely).…
Do you have a link? I am very skeptical that merely tossing out large-sounding numbers during an interview would have any influence on your likely salary range. In situations like that, your potential employer usually has a preconceived idea of what a "reasonable" salary for the position is; intuitively, you'd need to make a fairly strong suggestion to get them to anchor on a different figure (rather than, say, the salary they are already paying to other employees in a similar job function).
