You can find out your interests, according to Twitter, under your "Settings and privacy" tab.
Select "Your Twitter data," which is found all the way toward the bottom of your settings list.
Scroll down to the section titled "Interests and ads data." Not only can you find your "inferred interests" collected by Twitter (the first section), but you can also discover what data Twitter has collected — and shared— so it can personalize the advertisements it shows you on its platform.
Some of my Twitter interests make sense, since I do report on news and technology, after all. But some of the others don't make much sense — specifically my apparently significant interests in, "Shrek is getting a reboot by producer behind Despicable Me" and "People are calling The New York times following Press Secretary Sarah Sanders' statement."
