The study I linked to is absolutely not a "narrow experiment" - it's the largest and most thoroughgoing study of its kind ever done. The study you're linking to, by contrast, is a narrow experiment, is more than three years old, and has been superseded by new data. It'd probably be worth actually reading the link I gave.
Huh? Your study is a single experiment, which sends a single modified resume out to people and asks their opinion on pay/qualifications.
In contrast, the one I linked to examines real market outcomes at multiple career events. Unless you believe the situation has changed significantly in the past three years, your criticism of the age of my study is irrelevant.
