The Political Power of Inertia

"... people, organizations, and other agents have diverse interests; action to try to produce change is costly; and the benefits of those costly actions are often diffuse. Under these circumstances, a tally of expected costs and benefits will often discourage agents from taking action, tempting them instead to forego those costs and look to free ride on the contributions of others instead."

"Despite our deep-rooted desire for change and spontaneity, our daily mobility is, in fact, characterized by a deep-rooted regularity."

"Even as we recognize that the calendar makes for a crude and arbitrary marker, we like to think that history visibly marches on, on a schedule we can codify.
The more I dove back into the weeds of 1964, the more I realized that this is both wishful thinking and an optical illusion. I came away with a new appreciation of how selective our collective memory is, and of just how glacially history moves."
