Two people X and Y. What is the name of the argument that falls under X not being as "good" as Y, but X knows Y is doing something wrong in a subject. But Y's primary counter-argument says that X isn't creditable because he isn't as good.
An easy example to get the point across, but isn't the subject I'm applying it to, would be weight lifting. I know a buddy is doing incorrect form, but he lifts more than me. Since he lifts more than me/has been doing it longer/has more experience in said subject, he feels like he doesn't need to take my advice and say that he's doing it incorrectly, even though he's doing the movement incorrectly. He would only take advice from someone stronger/more experienced. (I'm not looking for an answer to this such as you need to talk with him about getting hurt...ect..ect.. Just using this to paint the picture).
Is this a category for this argument? Does it have it's own title or wiki page?
