This question already has an answer here:
It was made evident on the Stack Overflow question Search algorithm but for functions and many others that people with famous names in their fields answer questions and (granted are usually correct) get an insane number of upvotes for their answer that other people with lower reputation points also post.
I can't help that feel that a well known name basically means extra reputation points earned for every answer. Part of me wants to say that there should be some form of bottleneck on reputation: as you gain more you gain less. Then you can have people on 5k answering questions and getting good reputation from it while big names with 50-100k can answer a question, still get reputation point, but the mental number of upvotes for simply being a big name won't tip the scales too much.
So for all the people that decided to downvote my discussion on this point here is Sven Marnach talking about it:
Jakob, I actually do think you have a point.
There is a slight bias towards high-reputation users (I wouldn't really call them "famous").
In my experience, however, the most important factors are speed and correctness, sometimes with far too much emphasis on speed.
See Fastest Gun in the West Problem for a discussion of this phenomenon, which I consider far more serious than the slight bias towards high-reputation users. – Sven Marnach 2 hours ago
