Why every civilization collapses:
Rule 1. Inbreeding produces stupid.
Rule 2: Low IQ parents have higher fecundity.
Rule 3. 50% of all populations have IQs below 100.
Rule 4. Modern roads and transportation allow more mediocre to seek better locations to breed.
Rule 5. Civilization increases the survivability of mediocre and mentally challenged offspring.
Rule 6. The intelligence of a nation’s leadership tends to follow the mental decline of the population.
Rule 7: The giant red reset button pushed by earth’s periodic magnetic reversals and solar flares from the sun remove global civilizations, and the game starts over.
