The research that my laboratory has been doing, that economists and psychologists around the country have been doing, has revealed something really quite startling to us, something we call the "impact bias," which is the tendency for the simulator to work badly, for the simulator to make you believe that different outcomes are more different than, in fact, they really are.
A investigación que levou a cabo o meu laboratorio, que desenvolveron psicólogos e economistas por todo o mundo, revelounos en realidade algo  bastante sorprendente, ao que lle chamamos o <i>nesgo do impacto</i>, que é a tendencia  do simulador a funcionar mal. Porque o simulador faiche crer que as diferentes posibilidades son máis dispares do que en realidade son.
