202 ASKING QUESTIONS<br />

question indicates different answers are possible. As is usually the<br />

procedure in surveys, we did not mention that the test was intended<br />

to measure general intelligence, since this could make the respondents<br />

nervous. <strong>The</strong> scoring of the results, however, is based on<br />

norms established in standard intelligence testing. This question<br />

was included in a mail survey that the respondents filled out in their<br />

homes and mailed back. In the usual situation, knowledge questions<br />

would not be asked on a mail survey, since respondents could look<br />

up the answer or ask for help. For this question, however, there<br />

would be nothing to look up; and it is unlikely, although possible,<br />

that respondents consulted with others.<br />

Techniques and Strategies for<br />

<strong>Asking</strong> Knowledge <strong>Questions</strong><br />

Sometimes researchers think they should do whatever they can to<br />

increase the percentage of people who answer a knowledge question<br />

correctly. Such efforts can instead only increase the amount of correct<br />

guessing. <strong>The</strong> key is to ask knowledge-related questions in a<br />

way that one gets the most accurate assessment of knowledge, not<br />

the highest assessment of knowledge. <strong>The</strong> following techniques can<br />

help you in this regard.<br />

Determining Level of Knowledge<br />

<strong>The</strong> examples suggest that knowledge questions help qualify respondent<br />

opinions and should be asked before attitude questions are<br />

asked. This order is essential if the knowledge questions are to<br />

screen out respondents who do not have sufficient information<br />

to answer detailed attitude questions. Even if all respondents answer<br />

the attitude questions, respondents will be less likely to overclaim<br />

knowledge and more likely to state that they do not know or are<br />

undecided in their attitudes if knowledge questions come first.<br />

If the attitude questions are asked first, respondents may feel<br />

they are expected to know about the issue and have an opinion. On
