This is a first scatch of the process of decision making:

System 1 Decisions Habbits
Most of the time, people use intutive thinking when they make decisions, which is carried by system 1. thinking that is being done by system-1 is somtimes not logical, nor it is sutiable to precise reasoning (which is handeld by system 2). This creates logical mistakes, and may influance decision making proufundly. Understanding the way system 1 works, is important to thus who want to faciltate wise deicsion by deliberation.Most of the work in this page was based on Kahnaman's book "Thinking Fast&Slow"[1]
Biased Observations
Media Baised Observations
To sell, the media should produce interesting news, therefore it will describe only events that may interest it's public. Kahneman suggested that the reason he thought that politicians fornicate more then physician and lawyers, is since politicians are the subject of news, while the others do not make headlines when they are caught in adultery (p. 7). He suggested that the media bias will influence much of what we think about the world, and divert our ability get well informed and unbiased information.
Emotional Baised Observations
People that are stressed may look their surrounding in more dichotomic view, sorting the social world into good and bad, and will generalized from very few observations. Especially if the subject of observation is categorized as bad. For instance if a remember of another ethnic group will behave in a negative way, the observer will conclude that all the members of the ethnic group behaves in a similar negative way.
Brain process involving decision making
Usually People uses system 1 to decide. They will try to decide which option will give best values, based on information gatherd in the dlPFC[2], and calculated by the vmPFC[3]. Dolan also found that the PFC also connected to conflict solving.
When people scurtenise the world, they are compering the phenomena to information they gatherd in their NMOs. A contrediction is detected by the ACC, which activate system 2 in order to solve the contrediction. system 2 will oprate also when a novel task or complext rational task will presnt themselves.
When in stress, the FFFF system is put action. It seems that it inhibit ACC activation, thus, closing the actvation of system 2, and probably closing also jeneral empathy. The FFFF system may open a process to strength "famely" relations to strength group cohesion.
Other subjects of decision making
Mere-exposure effect - people will prefer objects they were more exposed to, but to a some degree. If the object was disliked in the first place, it will be more disliked. The effect is limited in duration, after 20 exposures, the effect diminish. When people were presnted with comercial to a drink with happy faces in mere exposer effect, they preferd it, over the same drink, without smiling object. This strenght the concept that people may decide in acordance to their feelings and not on a rational base.
