SUMMARY

The logic puzzle involves four individuals: two wearing red hats and two wearing blue hats, with one person positioned behind a wall. The primary question is which person knows the color of their own hat. The consensus is that the person behind the wall is the only one who can definitively know their hat color, as they can potentially see all three individuals in front of them. The discussion highlights the implications of visibility and knowledge in logical deduction, emphasizing that if the individuals in line cannot see their own hats, they cannot ascertain their colors without additional information.

PREREQUISITES
  • Understanding of basic logic puzzles and deduction.
  • Familiarity with concepts of visibility and information asymmetry.
  • Knowledge of logical reasoning techniques.
  • Ability to analyze scenarios with multiple variables.
NEXT STEPS

Delete this thread... the riddle itself is flawed, since it says the people in line can only see the person in front of them. IF it said "persons" then there'd be more info, but still not enough. It is also titled as a logic problem, not a "the wall was transparent!" riddle.
I don't think there's an answer.

Just realized this is an old revived thread from the distant past. Is it just me, or has that been happening a lot this weekend?
There was a firestorm of necromancy this past weekend.

I'm wondering how and why people dig up these old threads. You have to go the 10th page of thread topics in "Brain Teasers" to get to when this thread was started. Do people searching back that far just not realize how old the thread is, or do they realize it but find it so interesting that it still merits a response?

I'm seeing that the thread was revived in April this year by a one-time poster, so in this more recent revival it was only 2 months old.
