    The Psychology of Your Future Self

    "Human beings are works in progress that mistakenly think they're finished."

    The Psychology Behind Irrational Decisions

    The Psychology Behind Irrational Decisions

    Often people make decisions that are not "rational" from a purely economical point of view — meaning that they don't necessarily lead to the best result. Why is that?

    The Psychology of Inequality And Political Division

    "If we want to fix our politics, we have to do something about inequality," says social psychologist Keith Payne. Showing how economic inequality changes the way people see and behave towards one another, Payne helps explain the rise of the political polarization that's slicing up society -- and challenges us to think twice the next time we dismiss someone for the sake of politics.
