They are valid points, but in his case, after a PhD and 3 decades working with people, the phrase ' basic humanity' is a lot more memorable than, '12 things that will define you: here they are'. At some point, the knowledge is too dry unless transferred and having impact. People that want to change will look into what basic human virtues are, and more. The rest will remain adamant no matter how appealing the approach is. Sometimes professionals sum up things for the audience. The more professional they are, and the less time they have, the more one hears : maybe, most likely, etc. It's not that they don't evaluate the cases, it's the realization that a complete educative list will bore out the audience, and they will miss other, more basic, points.
