Check Bias FreeTypes of Survey Bias
Leading Questions
Questions that suggest a desired answer through their wording.
Double-Barreled Questions
Questions that ask about two things at once, making it impossible to answer clearly.
Loaded Questions
Questions that contain emotionally charged or assumption-laden language.
Absolute Questions
Questions using words like "always", "never", or "every" that force extreme answers.
Social Desirability Bias
Questions where respondents may answer to look good rather than truthfully.
What the Checker Detects
The AI bias checker scans each question for:
- Leading words: adjectives and adverbs that push toward a specific answer
- Double-barreled phrasing: questions asking about more than one topic
- Loaded assumptions: presuppositions embedded in the question
- Absolute terms: words like "always", "never", "everyone"
- Unbalanced scales: response options that lean positive or negative
Each flagged issue includes a severity rating and a suggested rewrite.
Writing Bias-Free Questions
- 1
Use neutral language: avoid adjectives like "great", "terrible", "amazing", or "frustrating" in question stems.
- 2
Ask one thing per question: if you see "and" or "or" in a question, split it into two separate questions.
- 3
Provide balanced response options: make sure positive and negative choices are equally weighted.
- 4
Randomize answer order when possible: position bias causes people to favor the first or last options.
- 5
Include a "Not applicable" or "Prefer not to say" option for sensitive topics.
