To expand not refute, > If truth is defined as beliefs which lead one to make decisions that cause you/your society to thrive This is 'metaphorical truth' to be precise. But it's only a part of the virality of memes, not the whole. Propagation can occur not just due to usefulness, but to other factors such as simplicity/replicability, human susceptibility / 'key in a lock' etc. If survival was purely metaphorical truth, then all surviving lifeforms would be 'the most true' (including viruses being 'true' to us). Which can be argued, at a philosophical level - But then we've expanded the definition so much as to lose relevant meaning at the pragmatic level. Porcupine throwing quills, and all that.
