- Our human brains value accuracy in perception only when accuracy supports our survival. In other words, you’ll never get snake-bit by avoiding a patterned leash left in the grass.
- Our incredibly complicated human brains protect us by perceiving and processing millions of bits of data at lightning speed, mostly outside our awareness.
- The decisions each of us make as we go through our day are the product of two basic systems: fast thinking and slow thinking.
- Fast thinking is, most of all, fast, typically outside of our control and awareness, and –perhaps most importantly—extremely efficient. Think of those times when you found yourself in your driveway after leaving work, with little memory of how you got there! I sometimes think of fast thinking as “running on automatic.”
- The connections we make in fast-thinking mode are generally the result of associations developed from our life experiences – even the vicarious ones we have when we watch television or explore social media. These associations may be, and quite often are, inconsistent with our beliefs.
- Slow thinking is deliberative, purposeful rather than automatic, and requires attention and effort.
- Most of the time, most of us function in fast-thinking mode – and that is necessary for our survival in a fast-paced, extremely stimulating environment. But we can switch to slow-thinking mode when necessary – provided we are aware that it is necessary.
- The anti-bias blind-spot causes us to more easily recognize bias in others than in ourselves, and that’s a problem. Lack of awareness can keep us from recognizing the need to switch to slow (i.e., more careful, deliberative) thinking.
