Contrastive analysis
The next stage in the like to dislike technique, once we've solicited the important submodalities of the liked substance and the disliked substance, is to compare the two sets of submodalities to find the drivers, the difference that makes a difference.
Start off simply, by comparing the two sets of submodalities side-by-side and noting any differences between the two sets.
Each of the differences will play a part in differentiating between a substance that the person likes and a substance that they don't like. Certain of the differences will have a more powerful influence than the rest, and these we call the drivers. As a rule of thumb, changing a driver will cause all the other submodalities to pull in alignment with the driver automatically.
Typically three distinctions will stand out as drivers - the location of the picture, the size of the picture or the difference between associated and dissociated.
Map across the contrasting submodalities
To complete the process we map the constrasting submodalities from the substance the person doesn't like on to the substance they do like - in this case we map the submodalities of cough syrup onto red wine.
For the exercise let's assume that our subject likes red wine and dislikes cough syrup. Their picture for red wine is a large, colour picture in the centre of their field of vision and is dissociated (they see themselves drinking it and enjoying it).
Their picture for cough syrup is smaller, in the bottom-right corner of their field of vision, is black and white and associated (they see a spoon of cough syrup being thrust toward their mouth).
To change like to dislike and have them dislike red wine, we ask them to imagine a dissociated, black and white picture of a glass of wine being thrust toward their mouth and have them move that picture into the bottom-right corner of their field of vision and make it the same size as the cough-syrup picture.
If we've correctly elicited the submodalities and correctly mapped across the contrasting ones, the drivers in particular, the person we are working with should find that they dislike red wine with the same intensity that they dislike cough syrup.
If, when they think about red wine, they also display the exact same unconscious physiology changes that we earlier noted were associated only with cough syrup and not with red wine, we have a very strong indication that the process has indeed achieved our desired outcome - like to dislike.
Simple, quick and effective.
(If you or the person you're working with decide that you really would prefer to like the substance again, take the opportunity to develop your skills further by reversing the process by returning substance back to it's original submodalities).
