This chapter discusses empirical evidence for a range of decision procedures underlying individuals’ choices in games. These include (1) quantal response equilibria. These are stochastic choice models where a player does not best reply to their beliefs, but instead chooses actions with a higher expected payoff with a higher probability. It also includes (2) cognitive hierarchy models where, roughly speaking, players possess different, discrete levels of cognition. A level-0 player chooses some fixed anchor strategy. And, recursively, having fixed the strategies of players of level 0,...,k-1, a level-k player best responds to a belief that all other players are of a lower level. Lastly, it includes (3) a variety of learning models.

In a time of great contest and confusion over the future of democracy as a governing principle, the example of Abraham Lincoln continues to provide encouragement and direction about democracy’s viability in the face of immense challenges. In The Political Writings of Abraham Lincoln, Allen Guelzo brings into one volume Lincoln’s most famous political documents and speeches from his earliest days as a political candidate under the banner of the Whig Party, to his election and service as the first anti-slavery Republican president, from 1861 to 1865, and the nation’s leader in the fiery trial of civil war. While many anthologies of Lincoln’s political documents routinely concentrate on his presidential years or only on his anti-slavery writings, Guelzo concentrates on documents from Lincoln’s earliest political activity as an Illinois state legislator in the 1830s up through his presidency. The result is an accessible resource for students, researchers, and general readers.
