For real results a changement in behaviour is necessary. In case it’s about consumer behaviour, search behaviour or social behaviour. Before usually the working habit went from knowledge through attitude to behaviour. However, a lot of behaviour is unconsciously. Consumers choose by heart. Rather than by their ratio. In other words, people say what they think, but do what they feel. That’s why Roorda translates scientific behavioural interventions to concepts that touch consumer’s feelings. Preferably right in their hearts.
