The opposite of a charismatic trap is a required tar pit.

A thing everyone knows you have to go through that no one wants to be stuck in.

But once someone touches it they can never get out.

When the person who gets stuck in it calls for help, they inadvertently pull in others who also get stuck.

Before you know it, every person is working on the least interesting and useful thing, instead of the primary thing that creates value and matters most.
