Bad decisions arise from faulty information, not faulty brain circuits
Making decisions involves a gradual accumulation of facts that support one choice or another. A person choosing a college might weigh factors such as course selection, institutional reputation and the quality of future job prospects.
Notes that researchers found that the error may not be in the brains processing but in the information. The report published in the journal Science finds a tendency for errors to arise when there is "noise" in the information being processed, not the brain.
As the brain acquires information in the pursuit of a decision, there are often impurities or a lack of clarity in the data being analyzed. A fundamental question neuroscientists have asked is whether bad decisions occur because of impurities in the information (sensory input) or because the brain simply makes mistakes when processing it.
Prior to this study, researchers mistakenly interpreted feedback from neurons as innately noisy, but the Princeton researchers were finally able to completely separate the sensory input from the internal workings of the brain. They found that there can be noisy sensory input while the neural networks in the brain are completely noise free, resulting in error. The subjects of the study were four college-aged participants and 19 rats.
The net result is that oftentimes poor information causes your brain to make bad decisions.
