I think "feeling" safe is an important component of a product. Of course the product has to also be effective, but if it's effective and people still don't trust it, then they won't use it. A good example of a similar situation is in the US military where we had to do yearly chemical weapons training that involved putting on a gas mask in a room filled with tear gas. The gas masks were already proven to work, but one purpose of the training was to make sure people trusted their equipment to keep them safe, making it more likely for them to use it when needed.
