I would be concerned about ideologically incorrect research, innocent mistakes, non-research-related activism, working for a disfavored person, being part of a disfavored ethnic group, etc.

> what do you think a government agency might see as misconduct that you see as legitimate?

I'm not the GP, but that one is easy:

- Discovering that some drug is ineffective (or worse) when the manufacturer has made party contributions;

- Discovering that some public policy does not benefit the population while it benefits some politician;

- Any research on a propaganda line with results that are not aligned with the official truths.

This is similar to how privacy-conscious people are told that “if you don’t have anything to hide then why are you so concerned about actually hiding things?”.

You are saying that as if the government is immune to corruption and abuse of power.

This is my thought Everytime someone defends increasing government power and authority. They always assume the government is going to act in good faith and never use the power in a harmful way. Almost as if they've never read a history book.

you probably never heard of the so called "political flighting" among university professors in China
