PricelessPsychology showed some of the weapons commercial vendors use against us.
Below I'll start a list of defenses we can use to thwart their evil intentions.
- How much does it actually cost?
Convert the dollar cost to units of something you like. E.g. that fancy dinner will cost me 15 bottles of beer;
am I willing to trade you 15 bottles of beer for that dinner?
- What alternatives exist?
Most items we want to buy have close substitutes. Ideally, we want to enumerate all
of the possible alternatives, and compare their costs / benefits.
