The biggest flaw in this idea is that almost nothing in your references applies to you! They pretty much cover only black and white names, not Oriental ones. You can't conclude that a white name benefits you because it would benefit a black person. Even in the Swedish study, a quick trip to Wikipedia shows that the number of foreign-born residents from east Asia in Sweden is a tiny percentage.
Furthermore, none of the studies you quote account for switching costs since they just compare people who already have the names, except for the Swedish one, but I would expect that the switching cost as a new immigrant is much less than for someone who has been living with his name for a while.
In addition, 'John Adams' seems common enough a name that it should be possible to verify whether that specific combination has any correlated benefits.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
