because you don't lie to yourself, you can easily take one path and know whether it's the right one or not.
split the novices to 3 groups (3-3-2) and send them along one path each.
Because you don't make lying to yourself a habit, if your path is the right one then all is well and the novice's answers will show who the liars are (if they do lie).
If your path is the wrong one, then you will get answers from 3 groups.
let's say group 1 (3 ppl) go to path A, while group 2 (3 ppl) go to path B, and group 3 (2 ppl) go to path C.
If group 1 & 2 & 3 all say their path is wrong, then path C is the answer and both ppl in group 3 are liars.
If group 1 & 2 say their path is wrong while group 3 produces mixed answers (yes and no) then path C is the answer and one member of group 3 is a liar while the other liar will remain unknown.
If group 1 says no while group 2 is no no yes and group 3 is no yes, then the yay-sayer of group 2 and the nay-sayer of group 3 is a liar. Path C is the answer.
If group 1 says no while group 2 is yes yes no and group 3 is no yes, then the nay-sayer of group 2 and the yay-sayer of group 3 is a liar. Path B is the answer.
If group 2 says no while group 1 is no no yes and group 3 is no yes, then the yay-sayer of group 1 and the nay-sayer of group 3 is a liar. Path C is the answer.
If group 2 says no while group 1 is yes yes no and group 3 is no yes, then the nay-sayer of group 1 and the yay-sayer of group 3 is a liar. Path B is the answer.
If group 3 says no while group 1 & 2 gives mixed answer then the minority (if there is any) of group 1 & 2 is lying.
If group 3 says no and group 1 says no while group 2 is no no yes then the two nay-sayers in group 2 is lying. Path B is the answer.
If group 3 says no and group 2 says no while group 1 is no no yes then the two nay-sayers in group 1 is lying. Path A is the answer.
If group 1 says no, group 2 says yes, and group 3 says yes then group 3 is made of liars. Path B is the answer.
If group 2 says no, group 1 says yes, and group 3 says yes then group 3 is made of liards. Path A is the answer
