Are we driven by emotions or rationality?

As Nassim Nicholas Taleb states: "One cannot make a decision without emotion"

Think about a totally rational person, who takes every alternative outcome into its decision. Think about the US President Obama who should decide between saving GM or let it fail. There are several reasons, which favours a bankruptcy and several reasons, which speak against it. Emotions serves as a lubricant of reason. 

Out of this insight, another question arises. Which decisions are favoured by our emotions?

John K. Galbraith suggests: The decisions, which cover the conventional wisdom. Audiences of all kinds most applaud what they like best. Who should like to hear shocking facts even if they are deemed to be true, they will be heard to late. The conventional wisdom in 2007 wasn't even a recession, nowadays we talk about the avoidance of a depression. Humans do not really care if decisions are true, they only need to satisfy the following three criterias:
  • We associate truth with convenience.
  • We find highly acceptable what contributes most to self-esteem.
  • And most imporant we approve most of what we best understand.
Conclusion

An adaptive environment is to complex to decide with rationality. We are led by emotion to simplify the consequences of our decisions. The consequences are simplyfied to those we best understand and those we find highly acceptable because of the reasons mentioned above.
