This situation is possible. Deliberately doing it may be for improper purposes, such as being driven by the interests of the brand, having a cooperative relationship, or out of some kind of favoritism, etc., thus violating the principle of objectivity and impartiality, emphasizing only the advantages and deliberately not mentioning the disadvantages. Unintentional situations are also more common. For example, if an individual's own experience is limited, he does not have a comprehensive understanding of all aspects of the brand, and he only answers based on his own limited experience, he may inadvertently miss the shortcomings; or if he answers in a hurry when the information is not collected sufficiently, it is easy to ignore the shortcomings and only mention the advantages. In order to ensure the objectivity and accuracy of the answers, respondents should try their best to comprehensively and in-depth understand all aspects of the relevant brands, and explain them in a fair and objective manner.
