Under time pressure, people tell us what we want to hear -- ScienceDaily

To test this assumption, Protzko, Zedelius and their UCSB colleague Jonathan Schooler devised a test of 10 simple yes-or-no questions, such as "I sometimes feel resentful when I don't get my way," and "No matter who I'm talking to, I'm always a good listener." Through a survey, respondents were asked to take fewer than 11 seconds, or alternatively, more than 11 seconds to answer each question.They found that the fast-answering group was more likely to give socially-desireable answers, while the slow answerers and the ones who were not given any time constraints (fast or slow) were less likely to do so, Protzko said.
