As we\u2019ve already said, \u201cAny act or decision that can potentially influence the survey results and drive them away from <a href=\"https:\/\/www.surveycrest.com\/blog\/guidelines-for-business-surveys\/\" target=\"_blank\" rel=\"noopener noreferrer\">the true picture<\/a> is known as survey bias.\u201d<\/p>\n<p><strong><u>Important  Note:<\/u><\/strong><\/p>\n<p>While experts agree that survey biases cannot be fully eliminated from research (uncontrollable external factors can always play a role), the goal is to minimize unintentional bias as much as possible  and exclude intentional bias completely.<\/p>\n<p>Remember, a biased study will always produce  inaccurate results that would be invalid and could not be applied to the broader public.<\/p>\n<h2>Interviewer Bias<\/h2>\n<p>Interviewer bias occurs when <a href=\"https:\/\/globalowls.com\/best-ai-survey-question-generators\/\" target=\"_blank\" rel=\"noopener noreferrer\">survey creators<\/a> or interviewers consciously or unconsciously try to influence the survey process, resulting in skewed findings.<\/p>\n<p>Based on what causes it, interviewer bias can take many forms. Some major ones are listed here:<\/p>\n<h3>\u2022 Non-verbal cues<\/h3>\n<p>When the interviewer uses nonverbal behaviors \u2014 body language, facial expression, and gestures \u2014 to either intentionally or unintentionally influence the respondent to produce certain answers.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<p>The interviewer nods or raises an eyebrow or shifts uncomfortably in the seat when hearing a certain response or asking a certain question. This can lead the respondent to align their answer to fit the interviewer\u2019s apparent expectation.<\/p>\n<h3>\u2022 Tone and attitude<\/h3>\n<p>When the interviewer\u2019s tone or attitude displays their approval or disapproval of a certain question or answer. It happens when the interviewer becomes animated when talking about a certain  topic or shows disinterest when hearing something else. Respondents who match the interviewer\u2019s preferences may alter their responses to fit the displayed preferences.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<p>In an <a href=\"https:\/\/www.surveycrest.com\/blog\/awareness-attitude-usage-survey-halloween\/\" target=\"_blank\" rel=\"noopener noreferrer\">awareness and usage survey<\/a>, a respondent may choose not to elaborate on their negative experience if the interviewer shows displeasure about the topic. This may result in a study that highlights positive experiences and downplays negative ones.<\/p>\n<h3>\u2022 Probing or prompting<\/h3>\n<p>This is the type of interviewer bias that  results from asking leading or suggestive questions that steer towards a  certain response. Interviewers may unintentionally provide hints that influence  a respondent on what to say.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<p>During an HR survey, the employee is asked about instances of successful <a href=\"https:\/\/www.surveycrest.com\/blog\/deal-with-difficult-boss\/\" target=\"_blank\" rel=\"noopener noreferrer\">conflict resolution with a difficult boss<\/a>. The condition of \u2018successful\u2019 may tell employees to only focus on experiences that result in a positive outcome.<\/p>\n<h3>\u2022 Personal bias<\/h3>\n<p>When the interviewer allows their personal opinions, beliefs, or prejudices to influence the research process in any way or to interpret the final results in a certain light. It is also often referred to as favoritism or discrimination.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<p>Instead of simply asking, \u201cWhat is your stance on same-sex marriage?\u201d, the interviewer leads with, \u201cDo you believe in traditional marriage values?\u201d<\/p>\n<p>These loaded or <a href=\"https:\/\/www.surveycrest.com\/blog\/survey-sucks-list-of-donts\/\" target=\"_blank\" rel=\"noopener noreferrer\">emotionally charged questions are a huge no-no<\/a>. They may give you the answers that you\u2019re looking for but they won\u2019t show you  the real picture.<\/p>\n<h3>\u2022 Reporting bias<\/h3>\n<p>This type of interviewer bias involves sharing survey results that either partially or completely omit certain findings. This happens when the study wants to downplay a certain reality or when they are unsatisfied with the results.<\/p>\n<p><strong>Example:<\/strong><\/p>\n<p>If a <a href=\"https:\/\/www.surveycrest.com\/blog\/surveying-gen-z-preferences-expectations\/\" target=\"_blank\" rel=\"noopener noreferrer\">researcher studying Gen-Z<\/a>\u2019s social media habits and mental health has a preconceived negative notion about this dynamic, they may emphasize data that highlights this correlation while oversimplifying more nuanced findings.<\/p>\n<h2>How To Avoid Interviewer Bias?<\/h2>\n<p>Mary K. Salazar, a University of Washington professor has talked of <a href=\"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/216507999003801203\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">8 preventive techniques that address correcting interviewer bias<\/a>. Here is a quick and simplified version of those suggestions:<\/p>\n<p align=\"center\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.surveycrest.com\/blog\/wp-content\/uploads\/2023\/09\/Enhancing-Online-Survey-Quality.jpg\" alt=\"Enhancing Online Survey Quality\" class=\"wp-image-5386\" title=\"Enhancing Online Survey Quality\" width=\"800\" height=\"1195\"><\/p>\n<ol start=\"1\" type=\"1\">\n<li><strong>Better training of interviewers: <\/strong>Train your researchers better. Ask them to sit in field interviews, give them the study material, and show them model interview tapes. Your training sessions must focus on teaching about research integrity and how to set personal prejudices aside.<\/li>\n<li><strong>Clarify the interviewer&#8217;s role and expectations: <\/strong>When the respondents don\u2019t know what the interview is about, they may give confusing answers. So without leading the respondents, <a href=\"https:\/\/www.surveycrest.com\/blog\/successful-survey-introduction\/\" target=\"_blank\" rel=\"noopener noreferrer\">introduce your research topic<\/a> to them and what you, as an interviewer, are attempting to learn.<\/li>\n<li><strong>Avoid using emotionally loaded words: <\/strong>All kinds of leading or loaded questions must be avoided at all costs. Always strive to <a href=\"https:\/\/www.rephraser.co\/\" target=\"_blank\" rel=\"noopener noreferrer\">rephrase<\/a> your questions and <a href=\"https:\/\/www.surveycrest.com\/blog\/guide-to-gender-pronouns-work\/\">remain gender-neutral<\/a> too.<\/li>\n<li><strong>Start big and narrow it down: <\/strong>Start with broader topics and narrow them down to specific questions. It will also help your respondents understand the context and prepare them to answer the most crucial questions with more understanding.<\/li>\n<li><strong>Ask open-ended questions: <\/strong>A research interview is the best setting to get as comprehensive a picture as you can from <a href=\"https:\/\/www.surveycrest.com\/blog\/identify-core-customer-base\/\" target=\"_blank\" rel=\"noopener noreferrer\">your core audience<\/a>. So ask open-ended questions and see what they have to say.<\/li>\n<li><strong>Pay attention to question timings: <\/strong>Are you giving some questions more attention or time? Because if you do, your respondents may follow suit. It can result in a skewed study where one area of the topic has more nuanced data than the other. So, try to divide your interview time equally among questions.<\/li>\n<li><strong>Be careful of the shift of topics: <\/strong>If you\u2019re shifting too quickly between topics, the respondents might think these are unimportant questions or you\u2019re in a hurry. In both cases, you\u2019ll get surface answers with no complex thoughts.<\/li>\n<li><strong>Summarize with care: <\/strong>Try not to add your personal commentary to the results when summarizing. Your personal opinions may make you see patterns when there are none. Strive to       remain objective and follow where the data takes you.<\/li>\n<\/ol>\n<h2>Conclusion<\/h2>\n<p>Biases can creep into the most well-intentioned surveys, so our job as researchers is to try and minimize these occurrences.<\/p>\n<p>We hope our Survey Bias series will help you stay on the right track when designing your business surveys and research studies.
