We would all like to believe that humans make decisions based on facts and logic. If we just educate people about what they need, they will do it. Of course it doesn’t work that way at all. If education and telling worked everyone would floss, no one would smoke and we’d all be at our ideal weight.
The fact is that in order to have people accept our recommendations we need to communicate effectively and engage people emotionally. Digital technology, which includes photos, x-rays, video and even the Internet allows us to do that faster and better than ever before.
