Stacked questions, in the context of communication and conversation, refer to a series of questions asked together without waiting for a response to each individual query. This approach can lead to overwhelming the respondent, as it requires them to remember and address multiple points simultaneously. Stacked questions are often used unintentionally but can also be a deliberate tactic in various communication settings, such as interviews or debates, to challenge or pressure the respondent.

For example, in a conversation, one might ask, "How was your weekend? Did you go out? Who did you meet? Did you enjoy it?" Here, multiple questions are asked in rapid succession, which can make it difficult for the person to give a thorough and thoughtful response to each one.

Stacked questions can lead to confusion, inadequate answers, or an inability to address all points raised. They are generally considered less effective for deep or clear communication, as they do not allow the respondent time to think and respond to each question individually. In settings where detailed, thoughtful responses are desired, it's better to ask one question at a time and allow for a complete answer before moving to the next question.

Ovida's data shows that the practice of stacking questions is more common than most users assume, but that awareness and practice can rapidly eliminate this unintentional behaviour from our communication patterns.
