The two decision systems in the slow and rapid human brain.

The two decision systems in our brain!

Is man a rational being?

In 2002 an Israeli psychologist, on behalf of Daniel KahnemanHe wins the Nobel Prize for the economy. His research has changed the vision of the psychic mechanisms of the decision -making process and has opened the way to a different approach to economic behavior.

Kahneman has shown that many of our decisions, which should be logical, are actually emotional and impulses.

The two decision systems in our brain:

• The decision -Pare the system number 1 calling «Think quickly» (fast thinking) is unconsciousIt is based on intuition and does not require effort or voluntary control.

• The decision -Pare system number 2 calling «Think slowly» (slow thought) is aware, uses logic, abstract thought and requires a lot of effort.

Biologically speaking we have this:

The decision -making system 1 (also called Elefant – Jonathan Haidt the book «Happiness») it is composed of:

• The cerebral trunk or rectilian brain, head of the vital functions of the body (breathing, digestion, blood pressure) and transmission of information from the body to the brain and vice versa.

• The limbic system or the emotional brain manages the emotional response to external stimuli.

• Tonsilla manages anxiety, sadness and responses to the state of fear.

• The hippocampus manages the formation of short and long memory.
  
  So the structures of the limbic system are involved in motivation, emotion, learning and memory. The attachment circuits also live here.

This system is common in all mammals, it develops completely up to the age of 15 and has the main role of survival[coniquatrobisognidibase:security/sexauto-autonomy(confidenceofthe[Cucelepatrunevoidebazrent:Siguranțăfizicăstatutreproduction/Sexautonomie(încredereaciantoțidescurcasingur)[coniquattrobisognidibase:sicurezzafisicastato/sessoautonomia(fiduciachepuoigestiretestesso)[cucelepatrunevoidebază:siguranțăfizicăstatutreproducere/sexautonomie(încredereacătepoțidescurcasingur)

These universal programs have specific answers for each of us, depending on our life history.

From Example: let’s take a conflict in public, a man will jump to the rhythm or increase the tone, another will retire, another will cry, another will give up immediately, another will try to mediate. These reactions are of system 1, which has decided quickly, associating with events, pleasant or unpleasant, lived by the person in the past, which is the best reaction.

The decision -making system 2 (also called Căliantț – Jonathan Haidt Book «Happiness») It is located in the neocortex, the brain structure that distinguishes people from the rest of the mammals.

In the neocortex, the prefrontal cortex is the main character and deals:

• Planning and vision in the future;

• logic;

• Creativity and abstract thought;

• recognition of subtle irony and sarcasm;

• the perception of the emotions of others;

• maintain attention; o suppression of involuntary impulses.

Even if we like to believe it System number 2 (rider) He is responsible for the decisions we make, in fact our life is mostly controlled by System n. 1 (Elephant).

Why? Because it doesn’t consume a lot of energy,

The pilot takes time for analysis and deductions, complex activities, or effort and we are built to preserve our resources. And how would it be to look at every step every step we take or, when we drive, we wonder why we press the brake? In each situation, the first reaction has system 1 which transmits suggestions (intuitions, emotions, intentions) to system 2, currencies, accepts or changes them. The whole process is extremely fast, conscious or unconscious.

Decisions based on system 1 are quick and easily influenced by external factors.

We are manipulated daily, from the commercials, to the positioning of goods on the shelves, to the images in stores and online, to the words used.

Some cognitive errors of system 1 that influence our decisions:

• Prejudice of excessive trust – The tendency to have too much confidence in one’s own thought and knowledge

• The prejudice of valability – The tendency to judge and decide the ideas that come to our mind, without questioning if they are correct.

• The anchoring effect – Estimate of a value based on a visual or auditory anchor to which we have been exposed. For example, the tendency to overestimate the value of an asset based on an initial displayed price, a technique used hard in sales.

• What you see is what you get – The tendency to make decisions only on the basis of the limited information presented in a certain context, without looking for further information.
  
  

• Analyze other perspectives, particularly attention to the declarations they generate. If I could see things like otherwise?

• Inquire from different sources, do not take «well» everything you feel.

• Don’t believe you smarter than others!

• Avoid things that seem too familiar to you. Analyze the conclusion you have reached and see is not just the desire to stay «in the comfort zone»?

• Do not give in to the first impulse, take time to think, let’s see the options in detail.

• Pay attention to the sellers who require fomo (fear of losing) and exert pressure on a quick response.

In the end, here are three problems, see what is the first response that comes to mind, that is, system 1, so what answer the 2 system has:

1. A baseball stick and a ball cost $ 1.1. The stick costs $ 1 more than the ball. How much does the ball cost?

2. Five cars Cos five shirts in five minutes. How many minutes hundred cars, hundred shirts will sew?

3. Pei A lake is a flock of ducks. Every day the stula doubles its volume, the Ducks occupied the entire lake in 48 days. How many days have they occupied half a lake?

What was the first answer in mind?

The correct answers are 5 cents, 5 minutes and 47.
