You may have heard that expectation aids suggestion. But to what degree?
The work of Young and Cooper in 1972 showed that 75% of the subjects who expected amnesia experienced it, whereas none of those who did not expect amnesia experienced it.
This suggests that expectancy is a key factor in making people respond to suggestion.
Worth considering just what expectation your pre-hypnosis discussion creates, as well as considering the effect of cultural suggestions when you work.
