What kind of research do you think is necessary if you’re to write outside your experience?

I think in pretty much every situation, as much research as possible is necessary, especially if the ‘experience’ is about another culture. If someone wrote about, say, mental illness, you’d think they’d put in the effort to research as much as they can about it. They could interview people with that illness, they could look online (or on paper) at other stories (real or fiction), and they could look up statistics and other information. The same goes for writing about other experiences. If I were to write about another culture, I would 100% make sure that I knew everything I could possibly know about that culture so that I didn’t say anything that could potentially come across as offensive or inappropriate.
