It all depends. Has @sokoloff contributed the same in the past? What is the value that age/experience has brought him in the things he does do and does not do? Performance reviews will always omit some aspect of the value the reviewed person brings.

Of course it's going to feel better just looking at the numbers. But then we get back to the same old problem - how do you define value and contributions and say A goes over B?
Sure, I'll admit that it doesn't create the best incentives for people who want to optimize their paycheck and standing, ie. ambitious people. However, this is fine in some circumstances when you're aiming to create a self-sustaining team.
> Does promoting me to lead that major new initiative put the company in the best position to succeed in the market and, via that success, continue to provide income for all employees?
'Best' is an ill defined, extremist term. For many tasks at hand, there are checkboxes that they have to tick, and for all you know, they might need not to be the best, but just at sufficient level to check those boxes. And that is enough.
Take an example where a dungeon boss needs a certain amount of damage dealt to it within a certain period of time to beat him. There are many class specialties, some doing more damage than others, but these are rare, and all of them meet the requirements. Are you going to spend extra time trying to grab that rare class specialty or take one of the abundant ones? Of course not.
