When filling out a survey, havenʼt you ever thought, "This is a hassle..." and ended up answering carelessly? This is especially true after walking around an exhibition, answering questions with a tired body. This phenomenon is influenced by the respondentʼs tendency to conserve their energy, known as "minimization."

Psychological research has shown that simply adding the phrase "Can you please answer thoroughly?" before a survey can reduce the rate of "neutral" responses in a five-point scale survey. To obtain accurate survey results, itʼs important to focus on the surveyʼs structure, as well as the initial explanation and communication.

Although "Can you please answer thoroughly?" is a bit awkward to say... haha.

Would "Please think carefully before answering" work instead? Or perhaps "Please answer honestly based on your intuition"?

That phrasing sounds good. In reality, that might be more practical.
According to the research, phrases like "Some people lie or answer carelessly in online surveys. Can you please answer this survey thoroughly?" as a pre-check and "Some people lie or answer carelessly in online surveys. Did you answer the above questions seriously? If you did not answer seriously, please let us know as it would greatly help in analyzing the data." as a post-check were both effective.

It also depends on the quality of the questions, right? To increase accuracy, mixing in similar questions to check for consistency can be very tiring. If the survey seems serious, people might want to answer seriously. However, if weʼre told "You must answer thoroughly," it might feel like weʼre doing a favor, and it could backfire.

Youʼre absolutely right.
The survey structure is the most important, and then the phrasing acts as an additional push.

Also, as you get older, it really feels like more of a hassle, haha.
