A miniature of tribal logic where a single phrase—and what was not heard before—decides everything.
The two islanders
Riddle statement
A judge visits an island where everyone belongs to one of two tribes:
- the truthful, who always tell the truth;
- the liars, who always lie.
He meets two islanders, A and B.
He asks A:
“Are you both liars?”
A responds in a low voice, and the judge cannot hear him.
Then B says:
“He said no.”
What tribe does each one belong to?
