How to frame survey questions to get honest response?
In my opinion, test-retest method would be suitable to your request.

This procedure is quite simple: individuals are asked to take the test and then take the same test again at a later date. The scores are then compared. The closer the scores are, the more reliable the test.

This methodology is appropriate for instruments such as IQ tests and surveys because there is little chance of people experiencing a sudden jump in IQ or suddenly changing their opinions.

I wish i have been helpful.
