Well-aimed and extremely necessary campaigns, for example in the field of alcohol and speed, have the result that road users behaviour is changed only temporarily. Not because he or she is persuaded of the necessity for another kind of behaviour on the road, but more because of the penalties threatened. This is the essence of the final limited outcome of all campaigns. They are aimed at a temporary change in behaviour, while hundreds of years of study of the human psyche have shown that behaviour can only be permanently changed if you try to bring about a change of mentality. One can however only bring about a change in mentality in children.
Adults are too set in old habits and behaviour patterns.
In their case only smooth off rough edges, but hardly change them. A good example of this position is education in the field of the environment. The enormous environmental awareness in the Netherlands is to be attributed to a good and continuous supply of information through the schools and the media. From a young age children are confronted with the need to take care of the environment. The result is that children are more conscious of the environment than their parents.
