Some of us might be familiar with the blue eyes riddle. We also might be familiar with the "solution". If you aren't - stop reading immediately and educate yourself, man.
What few people know is the answer to this 'riddle about a riddle':
- What information does the Guru give us?
(so you could perhaps say, that few people really understand the solution)?
This is non-obvious. If there's, say, 50 blue eyed people on the island, the Guru clearly tells us nothing new about the situation (we can see "someone" has blue eyes, duh!). However, I can say with confidence that without the Guru telling us "someone has blue eyes", nobody would've been able to leave the island.
Why is this?
Take some time to think, maybe discuss it in the comments, if you like. You can spoil yourself the the answer here.
