Duncan’s unique Effective Influence Model was created after years of learning, understanding and conducting experiments into the field of influence and persuasion. He wanted to design and easy to understand model that could elevate people’s influence and persuasion skills to make them more effective.

As we get bombarded by more and more curiosity hooks, advertising and marketing messages, we are slowly becoming desensitised to authentic persuasion and influence techniques. It’s no longer about being a great salesman or woman. In fact it never was. Being labelled as a great salesman simply means you’ve been caught. The result we should all be looking for in a sales process or negotiation comes in the form of the words “Thank you”.

A ‘thank you’ shows that we have cared. We can demonstrate that we care by finding a solution for our clients’ problems and demonstrating empathy with their needs.

Empathy is caring about what the people you care about care about. In fact, caring for others and perusing our business or personal goals is a cause and effect relationship.
