A behaviour that once paid gets defended for years by the memory of the payment.
The mind ties prosperity to whatever it was doing when prosperity arrived, and the tie hardens into a belief that pays out certainty for a lifetime. That belief sets the state, the state sets the loyalty, and the loyalty then recruits real evidence: the years were good, the cupboards were full, the ritual was running.
Suffering afterward finishes the case rather than breaking it, since every hungry season now reads as a receipt for what was abandoned. A vehicle that meets a need and one that tells the truth are different things, and relief cannot tell them apart. The price is a people who go on pouring out offerings beside their own famine and who hear a prophet as a threat to the food supply.
