We are making a simple Likert scale radio group for feedback and will group it as follows:
Please rate the service you received:
- Very poor
- Very good
According to usability guru Jakob Neilsen, radio choices should have one option selected as a default. In a typical Likert scale like above, what would be the most appropriate to select as default? 'Average', as it is in the middle or 'Very good', which might appear presumptuous?
