I vaguely but persistently recall a short story that I read while growing up about a group of people who try to stop a powerful alien consciousness from attacking Earth by forming some sort of group telepathy session and threatening it. Other details I recall:
- It didn't go well -- the alien figured out how to trap them, and then.. I dunno. Maybe a cliffhanger? Not sure.
- Specifically I remember them giving it "60 seconds" to leave, and it realized "if this period of time is meaningful to you, you must be pretty slow-thinking creatures".
- I think it wasn't a standalone story? Probably one in a series using the same characters?
- I probably read it in my dad's old copies of Analog (circa 70s).
