With it's lighting fast reactions, System One is present in almost every common situation. It's actions are sometimes unstoppable and can be trained to steal tasks from the second System. Depending on the complexity, here are some tasks that System One makes:<ul><li>Solves simple math like 2+2</li><li>Recognizes a good chess move (if you are a chess expert)</li><li>Reads words on big ads</li><li>Drives the car on a empty road</li><li>Makes you look in the direction of a sound</li></ul>

System One

Being slower but very powerful, this part of the brain can partialy suppes the other one while taking control on our body and forming logical and complex operations that need an attention span while being easily interrupted, like:<ul><li>Solves complex math like 412* 525</li><li>Searching for a person</li><li>Controlling your behaviour</li><li>Completing a formular</li><li>Parking a car</li></ul>

System Two

Our mind can easily and unknowingly fall in a priming situation where certain things prepare ourself to take a certain decision based on association.<ul><li>Looking at a pile of cash before a conversation can make us greedy</li><li>A bilboard with some imposing eyes can lower bad behaviour</li><li>Holding our finger in the mouth forms a smile that sparks a little bit of joy</li></ul>Unfortunately, a strongly primed System One cand fool System Two into believing it's story.

Priming the brain

Our brains have two "systems" that complement eachother, with their own capabilities, limitations and functions. <ul><li>System One is fast, automated and precise, but can be easily tricked and has a small working window.</li><li>System Two is slower, can make complex thoughts achieved in a specific algorithm and takes control over it's brother when he needs to with it's long but limited attention buffer.</li></ul>

System One and System Two

"The world makes much less sense than you think. The coherence comes mostly from the way your mind works.”"

<ul><li>Our brain have a very limited attenion buffer. Our System Two can't give more than he has. We need to prioritize it's tasks to make it work efficiently.</li><li>We will use the minimal effort law, thinking as little as possible, unless we act on it with all our thinking energy</li><li>If we let our intuition take control, we may give a wrong response, making us repeat the process with a deeper search in our memory, this time calling for the Second System</li></ul>

Attention and Effort

The guru to the gurus at last shares his knowledge with the rest of us. Nobel laureate Daniel Kahneman's seminal studies in behavioral psychology, behavioral economics, and happiness studies have influenced numerous other authors, including Steven Pinker and Malcolm Gladwell. In Thinking, Fast and Slow, Kahneman at last offers his own, first book for the general public. It is a lucid and enlightening summary of his life's work. It will change the way you think about thinking. Two systems drive the way we think and make choices, Kahneman explains: System One is fast, intuitive, and emotional; System Two is slower, more deliberative, and more logical. Examining how both systems function within the mind, Kahneman exposes the extraordinary capabilities as well as the biases of fast thinking and the pervasive influence of intuitive impressions on our thoughts and our choices. Engaging the reader in a lively conversation about how we think, he shows where we can trust our intuitions and how we can tap into the benefits of slow thinking, contrasting the two-system view of the mind with the standard model of the rational economic agent. Kahneman's singularly influential work has transformed cognitive psychology and launched the new fields of behavioral economics and happiness studies. In this path-breaking book, Kahneman shows how the mind works, and offers practical and enlightening insights into how choices are made in both our business and personal lives--and how we can guard against the mental glitches that often get us into trouble.
