"The PI is the deciderer" is a relative concept

Most of the time on the blog I get to address maybe a tenth of an argument; on a good day it maybe sneaks all the way up to a quarter. This works because for the most part the rest of the issues are assumed to be out there in the commentariat and readership. I assume I get into issues that are at least partially familiar to my readers. Over time, with multiple posts, a topic may be more or less covered, especially if other blogs are talking about the same issues from other perspectives.
At times however, I can get to assuming a little too much about the breadth of an argument space. One of these areas is when I knock on the whiny, disgruntled postdoc perspective. My blindspot is that I usually feel that postdocs (particularly the blogosphere variety) are bright and reasonable assertive people who have no trouble standing up for their rights and indeed are a little over the top with self-interest. So my comments on issues such as authorship and the ownership of data generated in the lab trend toward asserting the unique position of the PI as the ultimate decider of disputes, too bad.
I recently had reason to consider my positions in the context of cultures less familiar to me in which it is rumored/stereotyped/perhaps true that submission to authority is a little bit more pronounced than in a typical postdoc of my acquaintance. If such individuals exist, my prior words might be taken in an unintended way.
