Project 7: ML Classification - Outer Planets and Personality
=============================================================
Tests if ML can identify patterns between OUTER PLANET positions and
personality using REAL personality data from Open-Source Psychometrics Project.

DATA SOURCES (REAL):
- Open-Source Psychometrics Project (OSPP) Big Five data
  https://openpsychometrics.org/_rawdata/
- Birth year allows calculation of outer planet positions
- Jupiter, Saturn, Uranus, Neptune, Pluto signs from birth year

WHY OUTER PLANETS:
- These planets move slowly (1-30 years per sign)
- Birth YEAR is sufficient to determine their approximate positions
- OSPP provides birth year but not full date (privacy)

METHODOLOGY:
1. Download real OSPP Big Five test data with birth years
2. Calculate outer planet positions for each birth year
3. Train ML models to predict Big Five traits from planet positions
4. Compare against random baseline
