There should probably be guidance on this when you go to add a tag. When I write a post I just randomly put some tags and have never previously considered that it might be prosocial to put more or less tags on my post.
I think people vote on tags, so if more people agree that the tag is relevant, the article gets higher in the list. So extra tags (that people won’t vote for) do create some noise, but only at the bottom of the list.

This is how I think this works; I may be wrong.
