Our Brains are Lying to Us The “why” behind Design Thinking and Lean Startup by Hart Shafer

Hinweis der Redaktion

  1. Anchoring Pay this much for an item that they didn’t know the value for yes/no Then, had auction for items; ppl with higher numbers bid 60-120% higher than low numbers Even after laughing about how random the first question was
  2. Biases are how we can get through the day walk, talk, drive a car without conscious thought
  3. The learning loop
  4. People are terrible predictors of their own future behavior Gym memberships
