Here’s an uncomfortable truth: the researcher creating the survey is often the biggest threat to getting accurate data. While we spend considerable effort worrying about respondent bias—how survey-takers might answer inaccurately—we often overlook the more fundamental problem of researcher bias: how our own assumptions, beliefs, and blind spots shape every aspect of survey design.
The irony? Researcher bias typically occurs without malicious intent. It’s unconscious, systematic, and embedded in decisions that seem perfectly reasonable to us at the time—precisely because we’re making them through the lens of our own biases.
This comprehensive guide explores how to recognize and overcome researcher bias to design more objective and reliable surveys. Because the first step to eliminating bias isn’t better methodology—it’s recognizing that you, the researcher, are not immune to it.
Understanding Researcher Bias
Researcher bias occurs when the person conducting the research allows their expectations, beliefs, or preconceptions to influence the results of a study. It’s a systematic error that can distort measurements and affect investigations at every stage—from forming research questions to interpreting results.
The Critical Difference: Researcher vs. Respondent Bias
It’s essential to distinguish researcher bias from respondent bias:
Respondent bias: How survey participants answer inaccurately due to factors like social desirability, question wording, or recall issues.
Researcher bias: How the survey creator’s own perspectives, assumptions, and blind spots influence survey design, data collection, analysis, and interpretation.
Why researcher bias is more insidious: While respondent bias can often be mitigated through careful question design, researcher bias affects the very foundation of your survey—what you choose to ask, how you ask it, whom you ask, and how you interpret the answers. If your questions are fundamentally biased, no amount of good respondent behavior will fix it.
Why All Researchers Are Vulnerable
You might think: “I’m objective. I’m trained. I follow best practices.” That’s exactly what every biased researcher thinks.
The uncomfortable reality:
- Seasoned professionals are just as susceptible to bias as beginners
- Education and experience don’t make you immune
- Sometimes expertise makes it worse—you become so confident in your assumptions that you stop questioning them
- Your background, culture, and experiences create blind spots you literally cannot see without outside help
Researcher bias isn’t a character flaw—it’s a human condition. The question isn’t whether you have biases (you do), but whether you’re willing to acknowledge them and implement systems to counteract them.
Types of Researcher Bias in Survey Design
Understanding the specific forms researcher bias takes helps you recognize and address it.
1. Confirmation Bias
Definition: The tendency to favor, seek out, interpret, and remember information that confirms your preexisting beliefs or hypotheses while giving disproportionately less consideration to alternative possibilities.
Why it’s so powerful: Instead of testing a hypothesis (the scientific thing to do), researchers tend to try to prove it. We unconsciously design surveys to validate what we already believe.
How it manifests in surveys:
- Question selection: Only asking questions likely to support your hypothesis
- Wording bias: Phrasing questions to elicit responses that confirm assumptions (e.g., “Do you like the new, improved design or the old one?”)
- Sample selection: Choosing participants who validate your viewpoints
- Data analysis: Selectively focusing on data that supports preconceived notions
- Interpretation: Dismissing contradictory evidence as outliers or exceptions
Classic example: A UX researcher is convinced their design is successful, so they focus only on positive user feedback and dismiss negative comments or pain points as outliers. The survey questions emphasize aspects of the design they’re confident about while avoiding questions about potential weaknesses.
Real-world case: In one of the most famous confirmation bias cases, anthropologist Margaret Mead went to Samoa in the 1920s convinced that sexual behavior was culturally unique. She interviewed teenage girls and found exactly what she was looking for—evidence of a free-love society. The problem? She was so focused on confirming her hypothesis that she didn’t recognize when respondents were teasing her or telling her what she wanted to hear. Decades later, researchers discovered her conclusions were largely incorrect, but by then her biased findings had influenced generations of thinking.
2. Selection Bias (Sampling Bias)
Definition: When the selection of participants or data produces an outcome that’s not representative of the population you’re trying to study.
How it manifests:
- Selecting a non-random sample
- Missing crucial market segments
- Choosing samples that validate your own perspectives
- Surveying only people who are easy to reach
- Excluding groups that might contradict your hypothesis
Examples:
- Surveying only loyal customers when you want to understand overall customer sentiment
- Testing only tech-savvy early adopters when your product is meant for general users
- Conducting online-only surveys about technology access (excluding those without internet)
- Surveying only employees who volunteer (missing disengaged workers)
The grandmother microwave example: A grandmother notices her granddaughter doesn’t have a microwave. The grandmother thinks this means she cannot afford one (confirmation of her assumption about young people’s finances). In reality, the granddaughter prefers not to use one for health reasons. The grandmother buys a microwave. It sits unused in the closet.
In survey design: The grandmother would have designed her survey assuming microwaves are desirable and asking, “Which features would you want in a microwave?” instead of “Do you want a microwave, and if not, why not?”
3. Cultural Bias
Definition: When researchers’ own cultural background leads them to misinterpret or incorrectly assume meaning in respondents’ answers.
Why it’s dangerous: Words, phrases, and concepts that seem universal to you may have completely different meanings to others. What’s “common knowledge” in your world may be foreign in another.
How it manifests:
- Vocabulary misunderstanding: Using “common” words that are actually cultural jargon
- Assumption about experiences: Presuming shared knowledge or background
- Interpretation errors: Reading your own cultural context into respondents’ words
- Question relevance: Asking about things that matter in your culture but not theirs
Real-world example: Development workers surveyed villages about toilet access to reduce open defecation and child mortality. The survey design confused owning a toilet with using it. The researchers assumed people without toilets wanted them (their cultural assumption). They didn’t understand that in some communities, cultural and religious beliefs meant toilets inside homes were considered unclean. Result: toilets were built but went unused, wasting resources.
Another example: In developing economies, some people misunderstand Facebook to be separate from the internet or believe Facebook IS the whole internet. A Western researcher might write survey questions assuming universal understanding of “internet” vs. “Facebook” vs. “apps,” creating confused or inaccurate responses.
4. The Halo Effect
Definition: When your positive or negative impression of one attribute influences your perception of other unrelated attributes.
How it affects surveys:
- If you think a product is innovative, you ask questions assuming it’s also easy to use
- If you like a design, you unconsciously phrase questions more positively about all its aspects
- If you’re proud of a feature, you emphasize it in surveys while downplaying potential problems
Survey manifestation: “Our innovative, cutting-edge platform makes tasks easier. How satisfied are you with using it?” (The positive framing of “innovative” and “cutting-edge” biases how people think about satisfaction.)
How to reduce it: In interviews or surveys, describe one topic completely before moving to the next. This gives you time to understand a respondent’s point of view with more objectivity and nuance.
5. Question Order Bias (Primacy and Sequencing Effects)
Definition: When the researcher’s sequencing of questions influences later responses, not because of respondent psychology, but because the researcher designed the order to support their hypothesis.
How it manifests:
- Asking general satisfaction questions before specific problems (priming positivity)
- Grouping all positive aspects together, then all negatives (creating contrast bias)
- Asking leading contextual questions before the key question
Example: “Our company has been working hard to improve customer service. We’ve invested millions in training. How would you rate our customer service?” (The context primes positive responses.)
6. Funding Bias
Definition: Research funded by organizations with vested interests may be unconsciously designed to favor certain outcomes.
How it manifests:
- Asking questions that highlight positive aspects of sponsor’s goals
- Avoiding questions that might reveal negative findings
- Interpreting ambiguous results in favor of the sponsor
- Sample selection that favors positive outcomes
Real-world concern: Studies funded by pharmaceutical companies are more likely to show positive results for their drugs. Market research funded by a company may unconsciously be designed to validate product decisions already made.
Why it’s unconscious: Researchers aren’t usually deliberately falsifying data. Rather, dozens of small decisions—which questions to ask, which to omit, how to phrase things, which respondents to include—all subtly tilt toward results that please the sponsor.
7. The Hypothesis-Seeking Bias
Definition: Designing surveys specifically to prove rather than test your hypothesis.
The scientific method problem: Science is about testing hypotheses—creating conditions where your hypothesis could be proven wrong. But researchers often unconsciously design surveys where their hypothesis can only be confirmed.
How it appears:
- Only asking questions that could support your hypothesis
- Not including questions that would challenge it
- Framing questions so the “right” answer aligns with your expectations
- Not offering response options that would contradict your hypothesis
Example: You hypothesize that customers want feature X. Your survey asks: “How excited are you about feature X?” and “What do you love most about feature X?” You never ask: “Would you use feature X?” or “What problems might feature X create?”
8. The Expertise Blind Spot
Definition: When deep knowledge in a subject makes you assume things are obvious or universal that actually aren’t.
How it manifests:
- Using technical jargon without realizing it’s not common knowledge
- Assuming respondents understand concepts you work with daily
- Not explaining acronyms or insider terms
- Structuring questions around frameworks familiar to you but not to respondents
Example: A healthcare researcher writes “How satisfied are you with your PCP’s adherence to evidence-based treatment protocols?” Most patients don’t know “PCP” means “primary care physician” and have no idea what “evidence-based treatment protocols” means.
How Researcher Bias Enters the Survey Process
Researcher bias isn’t confined to one stage—it can infiltrate every phase of survey design and execution.
Stage 1: Research Question Formation
The bias: The very questions you choose to investigate reflect your assumptions.
Examples:
- Asking “How can we improve our customer service?” assumes customer service needs improving
- Investigating “What features do users want?” assumes features are the solution
- Studying “Why don’t people use our app?” assumes non-use is a problem to solve rather than a valid choice
Better approach: Ask open questions first. “What has been your experience with our customer service?” “What would make our product more valuable to you?” “Tell us about your decision regarding our app.”
Stage 2: Literature Review and Hypothesis Development
The bias: You find and emphasize research that supports your preconceptions while dismissing contradictory studies.
Example: You believe gamification increases engagement, so you cite all the studies showing positive results while ignoring meta-analyses showing mixed or null effects.
Better approach: Actively search for contradictory evidence. Assign someone to play “devil’s advocate” and find research that challenges your assumptions.
Stage 3: Survey Design and Question Writing
The bias: Question phrasing, response options, and survey structure all reflect what you expect to find.
Manifestations:
- Leading questions that suggest desired answers
- Incomplete response options that exclude possibilities you haven’t considered
- Scales that aren’t truly neutral
- Question order that primes responses
- Omitting questions that might contradict your hypothesis
Stage 4: Sample Selection
The bias: Choosing respondents who are likely to give you the answers you want.
Examples:
- Surveying only engaged users when you want to understand overall satisfaction
- Selecting customers from your “success story” list
- Recruiting from demographics you’re comfortable with
- Avoiding hard-to-reach populations that might have different perspectives
Stage 5: Data Collection
The bias: How you administer surveys and interact with respondents can influence their answers.
In-person or phone surveys: Your tone, facial expressions, and reactions can signal desired answers
Online surveys: The design, images, and context you provide frame how people respond
Stage 6: Data Analysis
The bias: You analyze data looking for confirmation rather than truth.
Manifestations:
- Cherry-picking data that supports your hypothesis
- Dismissing contradictory findings as outliers
- Running multiple analyses until you find significant results (p-hacking)
- Overinterpreting weak correlations that support your view
- Underinterpreting strong data that contradicts it
Example: Your survey shows 52% of users rate a feature 3 out of 5 or higher. You report: “Majority of users satisfied with new feature!” You ignore that 48% rated it below neutral.
Stage 7: Interpretation and Reporting
The bias: You frame findings to support preexisting conclusions.
Manifestations:
- Emphasizing positive findings, downplaying negative ones
- Selective reporting of results
- Interpreting ambiguous data in favor of your hypothesis
- Not reporting limitations that might undermine conclusions
Practical Strategies to Overcome Researcher Bias
Recognizing bias is the first step. Implementing systematic practices to counteract it is what actually makes a difference.
1. Pre-Registration: Commit Before You Start
What it is: Clearly outlining your research methods, hypotheses, and analysis plans before data collection begins.
Why it works: Once your predictions are documented publicly, you can’t unconsciously adjust your approach to get the results you want. You’re accountable to your original plan.
How to implement:
- Write down your hypothesis before designing your survey
- Document your methodology, sample criteria, and analysis approach
- Register it with a third party (even if just internally with stakeholders)
- Note any deviations from the plan and justify them
Benefits:
- Prevents post-hoc analysis (“I knew it all along!”)
- Reduces selective reporting
- Creates accountability
- Forces you to think through methodology carefully upfront
2. Employ Diverse Research Teams
Why it matters: Different backgrounds, perspectives, and experiences catch blind spots you can’t see.
What diversity means:
- Demographic diversity (age, gender, ethnicity, culture)
- Professional diversity (different disciplines, specialties)
- Cognitive diversity (different thinking styles, perspectives)
- Experience diversity (junior and senior researchers)
How it helps:
- Someone from a different culture catches cultural assumptions
- Someone from a different discipline asks “obvious” questions you haven’t considered
- Junior researchers question things senior researchers take for granted
- Multiple perspectives spot bias one person misses
Practical implementation:
- Include diverse voices in survey design meetings
- Have people from different backgrounds review questions
- Rotate who leads different research projects
- Actively solicit dissenting opinions
3. Implement Rigorous Peer Review
Why it’s essential: You can’t see your own biases, but others can.
Who should review:
- Internal peers: Colleagues who understand your work but weren’t involved in this project
- External experts: Researchers in your field who bring outside perspective
- Target population members: People similar to your respondents who can spot confusing or biased questions
- Methodologists: Experts in survey design who focus on methodology rather than content
What they should evaluate:
- Question wording for bias and neutrality
- Response options for completeness and balance
- Sample selection for representativeness
- Overall survey structure and flow
- Assumptions embedded in questions
- Missing questions that should be asked
How to make peer review effective:
- Provide specific guidance: “Look for leading questions, cultural assumptions, and hypothesis confirmation”
- Don’t be defensive—embrace criticism
- Have reviewers from different backgrounds catch different issues
- Do peer review before pilot testing, not after
4. Conduct Extensive Pilot Testing
What it is: Testing your survey with a small, representative sample before full launch.
What to test for:
- Do respondents understand questions as you intended?
- Are response options complete and appropriate?
- Does question order influence responses?
- Are there any confusing terms or jargon?
- Do certain questions consistently get skipped?
- How do different demographic groups interpret questions?
Critical: Include cognitive interviews:
- Ask pilot participants to think aloud as they complete the survey
- Have them explain what they think each question means
- Ask why they chose specific answers
- Probe for confusion, assumptions, or alternative interpretations
What you learn: Often, what respondents understand is shockingly different from what you intended. This is your bias revealed.
5. Practice Reflexivity
What it is: Systematic examination of your own potential biases and how they might influence the research.
Questions to ask yourself:
- What do I hope this survey will show?
- What would disappoint me if the data revealed it?
- What assumptions am I making about respondents?
- How does my background influence what I’m asking?
- What aren’t I asking because I assume I already know the answer?
- If the opposite of my hypothesis were true, how would I know?
Document your biases:
- Write down your expectations before data collection
- Note your assumptions about what you’ll find
- Identify personal or professional factors shaping your interests
- Record how you’re approaching the research problem
Why it works: Conscious awareness of your biases makes it harder for them to operate unconsciously.
6. Use Standardized Procedures
What it means: Apply uniform procedures across all phases of research to maintain consistency and reduce subjective decision-making.
Examples:
- Use validated question templates from research literature
- Follow established survey design guidelines
- Use the same introduction and instructions for all respondents
- Code and analyze data using pre-specified criteria
- Have multiple researchers code qualitative data independently
Why it works: Standardization removes opportunities for bias to enter through ad-hoc decisions.
7. Employ Blinding When Possible
What it is: Keeping researchers unaware of certain details that could influence their behavior or interpretation.
In survey research, blinding can mean:
- Having someone else write survey questions based on your objectives (removing your word choices)
- Having data analyzed by someone who doesn’t know the hypothesis
- Not telling data analysts which groups are treatment vs. control
- Having qualitative responses coded without seeing respondent demographics
Why it works: If you don’t know what you’re “supposed” to find, you can’t unconsciously look for it.
8. Seek Out Disconfirming Evidence
The practice: Actively hunt for data that proves your hypothesis wrong.
How to do it:
- Assign someone on your team to play devil’s advocate
- Ask: “What evidence would prove me wrong?”
- Look for exceptions and outliers in your data
- Give contradictory findings equal weight to confirming ones
- Analyze subgroups that might reveal different patterns
The mindset shift: Stop trying to prove you’re right. Start trying to discover what’s true, even if it means you’re wrong.
9. Report Honestly and Comprehensively
What it means: Share all findings, not just ones that support your conclusions.
Include:
- Both positive and negative findings
- Unexpected results
- Data that contradicts your hypothesis
- Limitations of your methodology
- Alternative interpretations of results
- Things that surprised you
Why it matters: Complete reporting lets others evaluate your work objectively and helps counteract your own interpretation bias.
10. Separate Question Design from Analysis
The practice: Have different people design questions and analyze results.
Why it works:
- The person analyzing doesn’t know what the question-writer expected to find
- The question-writer can’t adjust analysis to match expectations
- Creates natural checks and balances
Practical tip: If you’re a solo researcher, document your expectations before data collection, then set them aside during analysis. Analyze data as if you knew nothing about the project.
Specific Question Design Techniques
Let’s get tactical about removing bias from the questions themselves.
Use Neutral Framing
Instead of: “How satisfied are you with our innovative new design?” Better: “How would you rate the new design?”
Instead of: “Don’t you agree our prices are competitive?” Better: “How would you describe our pricing compared to alternatives?”
Ask Open Questions Before Closed Ones
Why: Open questions don’t limit responses to options you thought of (which reflect your assumptions).
Example sequence:
- “What has been your experience with our customer service?” (open)
- “Which of the following aspects of customer service are most important to you?” (closed)
This way, if respondents mention something in #1 you didn’t include in #2, you’ve learned your assumptions were incomplete.
Include “Other” with Write-In Options
Why: No matter how carefully you design response options, your list reflects what YOU think is relevant. “Other (please specify)” catches what you missed.
Critical: Actually read and analyze the “Other” responses. If many people use it, your options were biased or incomplete.
Provide Symmetric Response Scales
Biased:
- Excellent / Very Good / Good / Fair / Poor
(Three positive options, only two negative—biases toward positive responses)
Unbiased:
- Excellent / Good / Neutral / Poor / Very Poor
Test Multiple Question Formulations
The practice: Ask the same thing in different ways to see if wording affects responses.
Example:
- Version A: “Do you support the policy?” (might favor “yes” due to acquiescence)
- Version B: “Do you support or oppose the policy?” (balanced alternatives)
If results differ significantly between versions, you’ve detected wording bias.
Avoid Loaded Context
Biased: “Given the economic challenges facing families today, how important is affordable pricing to you?”
Unbiased: “How important is pricing in your purchasing decisions?”
The first version primes respondents with context that biases their answer.
Creating a Bias-Prevention Culture
Individual techniques help, but the strongest defense against researcher bias is creating a research culture that values truth over validation.
Institutional Practices
Encourage Null Results: Celebrate and publish findings that show no effect or contradict hypotheses. This reduces pressure to find significant results.
Reward Critical Thinking: Promote researchers who catch biases, not just those who confirm hypotheses.
Make Replication Valued: Value studies that replicate and validate previous findings, even if they’re less “exciting.”
Transparent Methods: Require detailed methodology reporting so others can evaluate for bias.
Team Norms
Psychological Safety: Create environments where team members can challenge assumptions without repercussion.
“Devil’s Advocate” Role: Assign someone specifically to argue against the hypothesis and find problems with the research design.
Regular Bias Audits: Review past projects for bias patterns—where have you been wrong before?
Diverse Recruitment: Actively seek team members with different backgrounds and perspectives.
Personal Practices
Intellectual Humility: Acknowledge what you don’t know. Value discovering you’re wrong.
Curiosity Over Confirmation: Get excited about unexpected findings, not just confirming ones.
Continuous Learning: Study cognitive biases, attend training, read about how other researchers have fallen into bias traps.
Ego Management: Step on your ego. Learn to value truth rather than “correctness.”
Real-World Example: Researcher Bias in Action
Let’s walk through how researcher bias can distort an entire survey, then show how to redesign it objectively.
The Biased Version
Scenario: A product manager believes their new app feature will increase user engagement. They design a survey.
Research question: “How much do users love the new feature?” (Assumes users love it—confirmation bias)
Sample: Sent to users who’ve used the feature at least once (Selection bias—excludes users who saw it and chose not to use it)
Questions:
-
“How excited were you to discover our innovative new feature?” (Leading—assumes excitement and innovation)
-
“Which of these benefits did you experience: Saved time, Improved workflow, Made tasks easier?” (Only positive options—confirmation bias)
-
“How satisfied are you with the feature?” (Following positive context—order bias)
-
“Would you recommend this feature to others?” (Only asks likelihood of recommendation, not actual usage intent)
Analysis: Focus on the 73% who said they were “satisfied” or “very satisfied.” Briefly mention that 27% were neutral or dissatisfied, calling them “edge cases.”
Conclusion: “Users love the new feature! Clear success!”
Problem: The entire survey was designed to confirm the PM’s belief, not test it objectively.
The Objective Version
Scenario: Same situation, but the PM recognizes the need for objectivity.
Research question: “What impact, if any, has the new feature had on user behavior and satisfaction?” (Neutral—allows for positive, negative, or no impact)
Sample: All users—those who used it, those who saw it but didn’t use it, and those who may not have noticed it (Representative—captures full range of experiences)
Questions:
-
“Have you noticed the new [feature name]?” (Yes/No/Not sure) (Establishes awareness without assumption)
-
IF YES: “Have you used it?” (Yes/No) (Captures adoption rate objectively)
-
IF YES to #2: “What has been your experience with it?” (Open-ended) (Allows positive, negative, or mixed feedback without priming)
- “Which of these describes your experience?” (Include both positive and negative options):
- Saved me time
- Made tasks more difficult
- No noticeable change
- Improved my workflow
- Created extra steps
- Made tasks easier
- Other (please specify)
- “How often do you use this feature?”
- Multiple times per day
- Daily
- Weekly
- Tried once, didn’t use again
- Tried once, plan to use again
- Other
- “Would this feature impact your decision to continue using our app?” (Measures actual impact, not hypothetical recommendation)
Analysis: Report all findings—positive, negative, and neutral. Break down by user segment. Investigate the “tried once, didn’t use again” group specifically to understand barriers.
Conclusion: “35% of users have adopted the feature and report time savings. 42% are aware but haven’t used it, primarily due to [specific reasons from open responses]. 23% weren’t aware it existed. Among adopters, usage is declining after first week, suggesting [specific issues].”
Result: Objective data that informs actual product decisions, even if it doesn’t validate the original hypothesis.

Key Takeaways: The Objective Researcher Mindset
Overcoming researcher bias isn’t about implementing a checklist—it’s about fundamentally shifting how you approach research.
1. Embrace uncertainty: You don’t know what you’ll find. That’s why you’re researching.
2. Value being wrong: Discovering your hypothesis is incorrect is success, not failure. It means you learned something.
3. Recognize your limitations: Your expertise creates blind spots. Your background shapes what you see and don’t see.
4. Systematize objectivity: Don’t rely on good intentions. Implement processes that force objectivity even when you’re unconsciously biased.
5. Seek diverse perspectives: Other people see your biases. Invite them to challenge you.
6. Test, don’t prove: Design surveys to test hypotheses rigorously, not to confirm them.
7. Report honestly: Full transparency about methods, findings, and limitations is the foundation of credible research.
8. Stay humble: The moment you think you’re immune to bias, you become most vulnerable to it.
9. Create accountability: Pre-register methods, involve peers, and make your reasoning visible to others.
10. Prioritize truth over comfort: Sometimes data will tell you things you don’t want to hear. Listen anyway.
Conclusion: The Researcher’s Responsibility
Researcher bias isn’t just a methodological problem—it’s an ethical one. When your bias distorts survey design, you’re not just producing bad data—you’re potentially causing harm through decisions based on that flawed data.
Products get built that users don’t want. Policies get implemented that don’t work. Resources get wasted on solutions to the wrong problems. Companies make strategic decisions on false premises. All because the researcher couldn’t see past their own assumptions.
The good news? Researcher bias is preventable. Not through willpower or good intentions, but through systematic practices that catch and correct bias before it affects results:
- Pre-registration creates accountability
- Diverse teams provide perspectives you lack
- Rigorous peer review spots what you can’t see
- Pilot testing reveals how your assumptions differ from reality
- Reflexivity forces conscious examination of unconscious biases
- Standardization removes subjective decision points
- Complete reporting makes your reasoning transparent
These aren’t optional “nice-to-haves”—they’re essential practices for credible research.
The ultimate question isn’t “Am I biased?” (You are.)
The question is: “Have I implemented sufficient safeguards to prevent my biases from distorting my research?”
Start today. Review your next survey through this lens. Identify where your assumptions are embedded. Invite critical feedback. Redesign with objectivity as the priority.
Because the most dangerous bias is the one you’re certain you don’t have.
