I have read, here on HN, that Glassdoor is not accurate. How do you realistically tell from outside if a company does treat their people well, or has a difficult culture? I've heard people mention churn, but people stick around even in those environments (especially for financial reasons) and churn is not always an indicator.

The challenge there is that everyone has different interpretations of 'a difficult culture'. What's important (albeit difficult) is establishing an understanding of the type of environment you thrive in and the types of environments you struggle in. With that understanding, it's important to spend time during an interview process asking open-ended questions that might reveal the aspects you love/hate.
