In general "being a person who", that is projecting identity, is boring. This is why you need polarization as a crutch. Being someone who's into competitive puzzle-solving, pop punk, or birdwatching is exactly the focus group tested "say something about yourself" no one really needs.

Now, having gone to a pop punk concert and sharing some observation about the crowd or surprising opening act might be interesting. Noticing that a lot of induction puzzles are based on simple features like even/odd is less interesting but still might interest someone.

Reading the room itself is generally considered interesting. If you go for a minute or two about the induction puzzles and your colleague/date/whoever shows no interest, you can turn mid-sentence and imputing "so... no interest in induction puzzles, the last one you saw was in third grade and even then it wasn't your first choice." It's just good conversation.

It's like in writing. Show, don't tell.
