text messaging is a surprisingly good way to get 1（公正的，坦白的） responses to sensitive questions, according to a new study to be presented this week at the annual meeting of the american association for public opinion research. "the preliminary results of our study suggest that people are more likely to disclose sensitive information via text messages than in voice interviews," says fred conrad, a 2 psychologist and director of the program in survey methodology at the university of michigan institute for social research (isr).
"this is sort of surprising," says conrad, "since many people thought that texting would decrease the likelihood of disclosing sensitive information because it creates a 3, visual record of questions and answers that others might see on your phone and in the cloud."
with text, the researchers also found that people were less likely to engage in 'satisficing' -- a survey industry term referring to the common practice of giving good enough, easy answers, like rounding to multiples of 10 in numerical responses, for example. "we believe people give more precise answers via texting because there's just not the time pressure in a largely asynchronous（异步的） mode like text that there is in phone interviews," says conrad. "as a result, respondents are able to take longer to arrive at more accurate answers."
conrad conducted the study with michael schober, a professor 4 and dean of the graduate 5 at the new school for social research. their research team included cognitive psychologists, psycholinguists, survey methodologists（方法论者） and computer scientists from both universities, as well as collaborators from at&t research. funding for the study came from the national science foundation.
"we're in the early stages of 6 our findings," says schober. "but so far it seems that texting may reduce some respondents' tendency to shade the truth or to present themselves in the best possible light in an interview -- even when they know it's a human interviewer they are communicating with via text. what we cannot yet be sure of is who is most likely to be disclosive in text. is it different for frequent texters, or generational, for example?"
for the study, the researchers recruited approximately 600 iphone-users on craigslist, through google ads, and from amazon's mechanical turk, offering them itunes store 7 to participate in the study. their goals were to see whether responses to the same questions differed depending on several variables: whether the questions were asked via text or voice, whether a human or a computer asked the questions, and whether the environment, including the presence of other people and the likelihood of multitasking, 8 the answers.
