Drive by Daniel H. Pink: Summary and Notes

Content: making decisions based on our first impressions and decisions
Anchor price: the first price we get and that determines our subsequent price considerations
Arbitrary Coherence: even things that shouldn’t factor into our price considerations (like product placement) may influence our decisions well into the future
“Initial prices are largely “arbitrary” and can be influenced by responses to random questions; but once those prices are established in our minds, they shape not only what we are willing to pay for an item, but also how much we are willing to pay for related products (this makes them coherent).” To become more rational: We all have repeated behaviours. Ask yourself what pleasure you’re getting from the things that you do and if they are worth it? Unexamined repeated behaviours can be a source of irrational decisions
Create new anchors. New experiences can help create new anchors and change old ways of making decisions
First decisions matter more than people care to admit as they determine our subsequent behaviours. Therefore examine your first decisions carefully
The True Cost of Zero
The price of zero causes people to react irrationally.
