Im surprised in you folks.
Ask one of them "Which way would the other tell me to go?"
So we have two types of people
Liars + Truthers (This is some weird OCD village)
And two paths
A + B
Lets say A is the correct path. And B leads to New Jersey.
If I ask one person "What path would the other tell me to take?"
A liar would tell me that the truthful person would tell me to go B (Because hes a liar)
A truthful person would also respond to the question with B (Because he tells the truth and knows the other person will lie and tell you to go B)
So just ask that question and do the opposite. Ta Da!
