:::::Related to reality is another way of saying empirical. To an astrologer, astrology is 'empirical' because it is experienced (and, I'm certain, shapes the astrologer's reality). This type of empiricism is not scientific (controlled neutral study) but it is to the observer/astrology a collection of 5 white swans and no black ones, generalized to the statement that all or most swans are white, so we can expect the next swan to be white. That doesn't make it correct, but it doesn't make it irrational, just non-scientific.
