Just last week I was at an unusually good talk by an Ogilvy Vice Chairman Rory Sutherland mentioned in the article.
>Rory co-heads a team of psychology graduates who look for "butterfly effects" in consumer behaviour - these are the very small contextual changes which can have enormous effects on the decisions people make
The talk's on youtube. https://www.youtube.com/watch?v=PWiB5H18aug&t=1187s Recommended if you are in to that stuff.
