Now, how about incentives? They seem cleverer. If you have one reason for doing something and I give you a second reason for doing the same thing, it seems only logical that two reasons are better than one and you're more likely to do it. Right? Well, not always. Sometimes two reasons to do the same thing seem to compete with one another instead of complimenting, and they make people less likely to do it.
Si tienen un motivo para hacer algo y yo les doy otro motivo para hacer lo mismo parece lógico que dos razones son mejor que una y es más probable que lo hagan. ¿Cierto? No siempre. Algunas veces dos razones para hacer lo mismo compiten una contra la otra en vez de complementarse y es menos probable que las personas lo hagan.
