Contrast the trap given below with the trap presented in the OP:
I think the other trap brings out something important, because both seem unfair. Both assure your destruction for not being prescient, because neither provided appropriate clues nor a fair chance at surviving the trap.
It is not unreasonable adventurer behavior to go around pulling levers. Especially after checking for traps. Especially when they guy with the highest chance for success pulls it. Even if some of them had been trapped.
It is also not unreasonable adventurer behavior to NOT pull the levers, especially after finding something suspicious about it, even if none of the previous levers had been trapped.
There are, I'd believe, only a minority of D&D players who enjoy having to outsmart the DM themselves to survive.
