Why add the Psychology of Influence to your skillset?
For any professional, the ability to influence people is a crucial skill. Whether you want people to buy, accept, take action, cooperate, quit something, start something right, participate, or agree, ultimately everything revolves around behaviour. By mastering the psychology of influence, you master the Art of Designing Behaviour. You start to understand how people make decisions and why they do (or don’t) do what they do. You will become much better at influencing yourself by getting a grip on people’s choice psychology.
