It basically sums up to that a good leader got the ability to trigger certain social ape-subroutines in peoples minds. Those who do not have that ability, nor the will to figure out how to get it, is best off by finding a strong and good leader to follow.
But I feel that there is something lacking here.
Authority.During my life, it's the one thing most people seem to respect. Authority. A simple example is how most people respond to people in uniform. They are more likely to follow orders from people in an uniform, it doesn't matter which, than a person not in one.
It is also the way people trying to scam you out of your account operates. By pretending to be an authority, which in our case is Blizzard.
There are many ways of being authorative. We've all heard of the expression "a natural leader".
While everyone can learn how to be authorative, you'll quickly notice the difference once an stressful situation arises, such as an emergency. The person who have learned to be authorative will then, in most cases, show insecurity and will give instructions in a much slower pace than normal, while the natural leader in most cases will react instantanious to whatever the situation call for.
And people will respond to the persons who shows signs of authority. Those who can distribute tasks and make people react in a manner that will ensure success.
And how does this relate to being a leader in the world of warcraft?
The exact same thing as in real life. It's not those who can crunch out numbers to summize a strategy that will work, that's evident by looking at battlegrounds, such as Alterac Valley.
It's the person that can show the proper authority.While it may be hard to do this in pure text, as that's all you usually got to communicate with, there are ways to do this. Exactly what that is, you'll have to figure out yourself, but usually, you can spot a leader when you see one. Bad leaders will be shunned, while you'll follow the good ones.
This is evident in raids. A bad raid leader will be doing things wrong, but people will still follow his instructions. These leaders are, I dare say, the ones running 4/12 ICC raids.
Of course, there are those who refuse to listen to any authoritive persons and insist on doing their own thing, often stating snide remarks in return to tactical instructions. You'll find those in raid environments as well, but much, much more quiet. Otherwise, they won't be allowed to join.
Authority is not the sole reason, however, but I do believe it's a key part of utilizing people's social ape-routines.
