Project 5: Mercury Retrograde Perception vs. Actual Events
==========================================================
Tests whether Mercury retrograde attribution reflects confirmation bias
using REAL data from technology outages, travel delays, and sentiment.
DATA SOURCES (REAL):
- Swiss Ephemeris: Exact Mercury retrograde periods
- Downdetector historical data (tech outages)
- FlightAware delay statistics
- Reddit/Twitter sentiment data
- Bureau of Transportation Statistics
METHODOLOGY:
1. Calculate exact Mercury retrograde periods
2. Gather real tech outage and travel delay data
3. Compare incident rates during retrograde vs direct periods
4. Analyze social media sentiment about Mercury retrograde
