my research article: Importance of haptic information in making purchase decisions

I want 10 questions to make interview

a. Your interview questions must not be leading/biased. The goal is to discover the motivations

for the behavior, reasons for doing or not doing it, and/or understanding the behavior.

b. Your questions must be broad-enough to allow participants to share their thoughts and

experiences. Avoid survey-like questions with Yes/NO answers.

c. Your interviews must capture basic demographic information such include age, gender,

ethnicity, and education level of the respondents.
