Why? Because if we were to plot our preferences in the short and long term on a graph, we would end up with a hyperbolic shape. This effect occurs because we have a non-linear perception of time and a temporal myopia, which makes clarity decrease as time increases. This phenomenon has applications in our everyday lives regarding health, consumption choices or financial decisions. It can cause us to make sub-optimal decisions, and can also be the root of more serious problems such as addiction and lack of self-control.
