4. In the text of this Chapter, we analyzed one result of the Presidential Debate Experiment: who won the debate. Consistent with conventional wisdom about the 1960 Presidential Debate, the experimental results showed that radio listeners reviewed Nixon's performance more favorably than television viewers did. This is an interesting result to be sure, but the data in the Debate Experiment Workbook's dataset allow us to analyze the results in more detail. In addition to asking subjects who they thought won the debate, Professor Druckman had subjects compared Nixon and Kennedy along several dimensions, including how much they agreed with them on issues, their integrity, perceived leadership effectiveness, and empathy. Each of these scaled variables ranges between o and 1 with higher values favoring Nixon relative to Kennedy. A.
