Ambiguous decision? Brain flip

Scientists have discovered that your brain responds emotionally and illogically when faced with making a decision from little information, according to a report from LiveScience. The California Institute of Technology conducted a study into ambiguous decision-making, or decisions made without certainty of the outcome or an idea of the probability of success.

In the experiment, test subjects were asked to make ambiguous decisions while their brains were scanned using a functional magnetic resonance imager (fMRI), according to the report. The brain scans showed that the decisions were often accompanied by activation of the amygdala, an area of the brain found to closely associated with fear.
