Removing the midpoint from a rating scale can make the results look more decisive. Every respondent appears to lean positive or negative. The chart is cleaner. The conclusion feels clearer.
But that clarity may be artificial.
A respondent who is genuinely neutral does not necessarily have a weak preference waiting to be uncovered. If you remove the neutral option, you may force them to invent one.
Every response communicates something different
Consider four answers that are often treated as interchangeable:
- Neutral: I have an informed position, and it falls between positive and negative.
- Insufficient experience: I have not seen or used enough to form a view.
- Not applicable: This question does not fit my situation.
- Prefer not to answer: I understand the question but do not want to disclose my answer.
Only the first response belongs at the midpoint of an opinion scale. The others explain why the respondent cannot, or will not, provide a position on that scale.
Combining them into one vague middle option makes the data harder to interpret. Removing the middle option altogether creates a different problem: respondents must choose a direction that may not reflect what they think.
What happens when neutral is removed?
A recent experimental study published in METRON compared personality scales with five response options, including “neither agree nor disagree,” against four-point versions without a midpoint.
The researchers used both between-subject and within-subject experiments across 12 personality scales. In the within-subject experiment, they could observe what people who initially selected neutral did when later presented with the same item without that choice.
The study does not show that neutral answers are always perfect. A minority of respondents appeared to use the midpoint as an escape, particularly when questions involved socially sensitive topics such as honesty or disagreeable behavior.
But that is an argument for giving respondents clearer ways to decline or qualify an answer. It is not a reason to eliminate a valid position for everyone.

The midpoint is a measurement choice
A balanced agreement scale might include:
- Strongly disagree
- Disagree
- Neither agree nor disagree
- Agree
- Strongly agree
Here, “neither agree nor disagree” is a substantive answer. It has a defined position between disagreement and agreement and should be included when calculating the scale’s results.
Responses such as “I don’t know” or “not applicable” are different. They sit outside the construct being measured and should normally be presented separately.
For example:
The reporting feature has improved my workflow.
- Strongly disagree
- Disagree
- Neither agree nor disagree
- Agree
- Strongly agree
Unable or unwilling to rate:
- I have not used the feature enough
- This feature is not applicable to my work
- Prefer not to answer
This structure lets respondents tell the truth without collapsing different situations into the same response.
Better options produce more useful signals
Separating these choices improves more than measurement accuracy. It also helps explain what is happening behind the score.
A high rate of insufficient experience may indicate an adoption, onboarding or product-discovery problem.
A high rate of not applicable may reveal that the survey reached the wrong audience or that the question needs better targeting.
A high rate of prefer not to answer can signal that the wording feels intrusive, the respondent lacks trust in the survey’s anonymity or the topic requires more careful handling.
A genuinely high neutral rate may mean the experience is unremarkable, the proposition contains competing considerations or the statement is too broad.
These are four different findings. A single catch-all midpoint, or a forced positive or negative answer, hides them.
Do not recode every non-answer as neutral
Once the survey separates these responses, the analysis must preserve the distinction.
Neutral should remain part of the rating scale. It represents a measured position.
Insufficient experience, not applicable and prefer not to answer should be reported separately rather than automatically assigned the midpoint value. Depending on the research design, they may be treated as distinct categories or excluded from the scale calculation while their frequencies are still monitored.
Otherwise, careful response design is undone during analysis.
When forced choice can still make sense
Forced choice is useful when the task genuinely requires a choice: selecting a preferred concept, ranking priorities or deciding which of two actions to take.
It is less defensible when measuring an attitude that can reasonably be neutral. Before removing the midpoint, ask:
Is neutrality impossible, or is it merely inconvenient for the analysis?
If the answer is the latter, an even-numbered scale may produce stronger-looking conclusions at the cost of weaker measurement.
Let respondents give the answer they actually have
Good surveys do not manufacture certainty. They distinguish between having no preference, having no basis for judgment, being outside the question’s scope and choosing not to disclose.
Neutral is a position. Insufficient experience is a limitation. Not applicable is a relevance issue. Prefer not to answer is a boundary.
Give each one its own place, and the resulting data will be more honest, more interpretable and more useful.
