Your date of birth could already tell enough a lot about yourself
WHY
Possibly, the more minimal data that can produce the more analises (whether you consider them reliable or not) is a date of birth interpreted by different astrologies
Pseudo Random as the least input
(Pseudo)Random relationing analisis gets whatever data and relates to whatever other data. Despite this looking banal, some peers could find this the more special analisis due to the less machinistic worried intervention it does.
Date of Birth as the more minimal input
Possibly, the more minimal data that can produce the more analises (whether you consider them reliable or not) is a date of birth interpreted by different astrologies.
Different astrologies have different ontologies and vocabularies. There is not a more perfect astrology than another. Someone could prefer some less developed astrology instead of another due to his-her local cultural heritage, andor because (s)he likes more the ontological sources andor vocabularies aesthetics. Nevertheless, remixes for them will be very useful for many mommentums.
There are some common estructures and keywords that can be translated from one astrology to another, while there is little effort done in this direction.
There is a permanent trend in theology to adapt existing documentation created time ago to the present days one is living in. Also, there could be initiatives like the Baha’i faith that tries to pack commonalities from the more famous religions into a new simplified one, but there has been less and not that much strong attempts to do that to-with astrologies themselves.
