I don't think about M-B or Tarot or astrology as predictive, they are mindfulness prods: interesting frameworks to break up and reframe the narratives we tell ourselves about who we are. A horoscope that tells me "this week will present challenges at work about money" is likely to prod me into mindfulness about work and money than I would be otherwise. Similarly, my ESTJ M-B type is more likely to make me mindful about where I get my energy and the ways in which rigorously analytical thinking may not be the way lots of other humans approach decisions.
