Linked claims
As a reflective prompt, astrology can function like any structured personality framework. Its value comes from the reflection, not the celestial mechanics.
Stage mentalists reproduce 'mediumship' on demand. Cold and hot reading are well-documented techniques.
A relationship-version of 'everything happens for a reason'. Same psychology, same lack of evidence.
Romantic-destiny belief is widespread and emotionally powerful. As a literal claim it has zero controlled evidence; as a meaning frame it produces both the deep-bond high and well-documented relationship dysfunction.
Tarot has no evidence of predictive accuracy. Apparent accuracy is reader skill plus client interpretation.
Like astrology used psychologically, tarot can function as a structured reflection prompt with no claim to literal divination.
