Every night at midnight, a ferry stops at the island. — flannel jesus

All the people except the guru have a pretty good idea what color their eyes are. After all they can count. — T Clark
They can count, but... so what? What's the logic? From the point of view of any person showing up to the boat, how has he logically deduced the colour of his own eyes? — flannel jesus
There are no mirrors or reflecting surfaces, nothing dumb. It is not a trick question, and the answer is logical. It doesn't depend on tricky wording or anyone lying or guessing, and it doesn't involve people doing something silly like creating a sign language or doing genetics. The Guru is not making eye contact with anyone in particular; she's simply saying "I count at least one blue-eyed person on this island who isn't me."
I was wondering if this forum has SPOILER technology — flannel jesus

Using the reasoning given by unenlightened, on day 100 every blue-eyed person would leave knowing that they have blue eyes, every brown-eyed person would leave knowing that they have brown eyes, and the Guru would stay knowing that they have neither blue nor brown eyes. — Michael
What's the reasoning for brown eyed people? Unenlightened gave reasoning for blue-eyed people — flannel jesus
