Ok... so 11 people weigh exactly the same... 1 person doesn’t... it doesn’t matter whether he’s heavier or lighter... the riddle only asked “weighs differently”.
Correct. So putting all 12 of them on the see saw is incredibly stupid. You don't find out anything that you don't already know.

4 vs 4 on seesaw
That will tell you the odd one out. Then you have 4.
2 vs 2
1vs1
And I’m not adding a riddle

These all only work if you know whether the odd man out is lighter or heavier.
Without that info, it is not possible in 3 moves.

What can you put in a barrel that makes it lighter?

There are 12 men on an island and 11 of them weigh exactly the same. There are no scales on the island. There is however there is a seesaw.
How do you determine the man who weighs differently?
If you use the seesaw, you can only use it three times.

But you’ll know after the second weigh if you have it right or not.

Weigh 6 on each side. The heavier side has your independent variable.
Cut the heavier side into two groups of 3, Your independent variable is again on the heavier side of 3
Last, pick two of the remaining three that includes our variable. If the two you picked weight the same, then the third guy is heavier. If the heavier guy is on one side of the seesaw, you will know.

I feel like this is the secret. Don't even use the seesaw, it's a crutch. There has to be a better way. Can we ask them how much they weigh?

So 6 guys on one side and 6 on the other... if only one of the 12 guys weighs differently, one side would go up/down respectively... therefore eliminating 6 men...
As I type this, I’m realizing that if you didn’t know which you were looking for, lighter/heavier, you could pick the wrong group of 6 and they’d all be equal and you’d lose.
I guess I fricked the riddle up from the jump.
My bad, gentlemen...
Moving on, anyon have any guesses on fr33’s riddle?

How do you know the guy who weighs differently is heavier?
Posted on 12/16/19 at 2:08 pm to Displaced
Yes it is lmao

What if the different person is lighter than everyone else?
