Source: Why districts are slow to charge market rates for water.

A technique to encourage conservation by charging high prices for frivolous extra water became legal only last year after Proposition 218.

Source: Hoarding

Summary
Hoarding is a comfort behavior that involves acquiring things, inability to take care of them realistically, and emotional difficulty parting with them. It seems to have three emotional components: redemptive belief, relating to objects as placeholders of meaning, and extreme guilt and fear of error in parting with objects.

Facts

🧐 Hoarding reduces discomfort, pain or anxiety, using the same pathways as pleasure and is intertwined with attachment feelings.

🤑 A redemptive belief lies behind each acquisition, and each additional item has a proposed future use greater than its present use.

🤔 The hoarding person relates to objects as placeholders or ‘vessels’ of meaning only, not as actual physical objects, and has extreme guilt and fear of error in parting with them.
