Since there is little to no evidence available on specific tactics, more work is needed to work out the most effective options and how they vary between groups (since we know face touching
varies across cultures). However, there is strong evidence that the best way of ensuring that these tactics happen is by using
“if-then” plans. These take the form of statements like “if I am looking at my phone, I will put my other hand in my pocket” or “if I sit down in a meeting, I will do ‘locked arms’”. Over time, these actions become habitual. The result is that people do not have to think about creating barriers to face touching: it just happens automatically.
An alternative possibility is that unprompted face touching occurs as a compulsive or habitual action, like nail biting. In those cases, the best option again is to
create an alternative behavior that
displaces the need away from face touching. Some options could be drumming fingers on legs or playing with a substitute object.
These may seem to be absurdly small and unimportant things to be discussed. In fact, they are crucial. Creating substitute behaviors and new barrier-forming habits are the most effective way of curbing face touching. We need to work out the most promising approaches and the best way of communicating them – fast.
