Do You Suffer From Decision Fatigue?

Via Scoop.itBounded Rationality and Beyond

In a The New York Times magazine article (To Choose is To Lose, August 21, 2011 – online version readable here), John Tierney presents compelling studies that show we compromise our ability to make sound decisions if we have exhausted our decision making ‘currency’ with prior decisions. When decisions are made at different parts of the day, the decisions vary because of the energy level of the decision maker — some of us are morning persons and others are night persons, etc.
At certain parts of the day, we suffer decision fatigue when making the same types of decisions over and over again (repetitive types) – such as reviewing proposals, evaluating applications, and deciding on parole of inmates. Before a meal (with energy lagging) can be a poor time for decision making.
Decision fatigue is an occupational hazard, such as for people working behind a customer counter (license bureaus, bank tellers). The fatigue often results in irritability as well.
It can happen to football quarterbacks at the end of a stress-filled game, where poor decisions are made.
No matter how rational and high-minded you try to be, you cannot make decision after decision without paying a biological price. This is different from physical fatigue because you are not consciously aware of being tired, but are low in mental energy.
When mentally fatigued, the brain looks for shortcuts, e.g., to do nothing or become reckless or act impulsively instead of thinking through the consequences.

Gigerenzer Gerd: non ragionare troppo segui l’intuito – Wise Society

Via Scoop.itBounded Rationality and Beyond

Secondo lo psicologo e neuroscienziato tedesco Gerd Gingerenzer si sceglie meglio quando ci si affida all’intuizione.Secondo lo psicologo e neuroscienziato tedesco Gerd Gingerenzer si sceglie meglio quando ci si affida all’intuizione. Che non è un sesto senso nè un impulso istintivo, ma slegata dal ragionamento ci permette di agire e decidere con grande rapidità e precisione. Imboccando spesso la strada giusta senza bisogno di troppi calcoli. Siamo abituati a considerare l’intelligenza un’attività intenzionale e cosciente guidata dalle leggi della logica, invece gran parte della nostra attività mentale è inconscia e si basa su processi estranei al ragionamento. L’intuizione non è puro impulso e capriccio, ma anzi ha una sua razionalità e sfrutta capacità acquisite dal cervello, permettendoci di agire rapidamente e con stupefacente precisione. La qualità dell’intuizione sta nell’intelligenza dell’inconscio e non c’è modo di farne a meno

Is the ADHD Brain More Creative? | The Creativity Post

Via Scoop.itBounded Rationality and Beyond

Does ADHD give people a creative edge?..The study found that Adderall did improve convergent thought. No negative effects were found on convergent and divergent thought measures. While more studies need to be done on ADHD and creativity, it does appear that there may be a correlation between ADHD and increased creativity.

Why Daydreamers are More Creative | The Creativity Post

Via Scoop.itBounded Rationality and Beyond

We don’t have to promote either working memory skills or imagination and daydreaming. We can promote both. And in so doing, we are promoting true creativity — creativity that is both novel and useful. In 1966, an important mentor and colleague, Jerome L. Singer, published his seminal book, “Daydreaming: An Introduction to the Experimental Study of Inner Experience.” Since then, the scientific study of daydreaming has taken off. A key theme that has emerged is the striking continuity between nightdreaming and daydreaming and the ability of creative people to harness this continuity. Neuroscience has allowed us to take this research to new, creative heights that were unimaginable when Singer published his book in ‘66.
