You're describing a very legitimate sampling error problem. I'm describing forced ideological conformity. Both exist in academia today.
If, in the spirit of the proposed "bias declaiming section", a social scientist made a point of saying that they're systematically biased against conservative and white/rural viewpoints, how do you think that would go over? Pat on the back for introspection?
Why don’t you think so? "Our own academic perspective limits us e.g. in our survey design and language, making it harder for us to connect with our respondents" is something I heard and learned over and over and over again.
Please don't add disclaimers like "I'm a liberal", it should not matter what your political opinions are. Shoot the message, not the messenger after all?
