It used to be impolite to not answer the phone, but since around 2005 or so the majority of phone calls have been scam, so it's no longer impolite. Say, did you know iPhone has a feature that makes it not ring if the number isn't in your contacts? System, "silence unknown callers". Email even more so.
Actual surveys are the same way. As a software developer I get asked to fill out surveys multiple times a day, so I generally don't. Every now and then I try but most of them are disguised marketing campaigns rather than actual questions. "How likely are you to recommend this product to your friends?" I do still fill out surveys that are official and infrequent, like work's yearly poll and the census, provided I can prove they are real.
