Whether or not survivability hinges on determining the truth or whether it does so necessarily has not been established. As it happens, your basic survival does hinge on your ability to determine the truth.
Does a caveman running away from perhaps a lion necessarily need to know that a lion is a four-legged carnivore that is closely related to other felines, or could he believe it to be a sack of potatoes dressed in a scary way yet *still* have the urge to run away and *survive*, despite whatever falsehoods he might believe?
