Today is the launch of 'Lemon. How the advertising brain turned sour', written by System1's Chief Innovation Officer, Orlando Wood.

In this episode we go through each chapter and cover the following topics:

• A creativity crisis – what’s our evidence and how can we compare ad effectiveness when we don’t have financial data?
• The left and right brain – how does each side view the world?
• What this means for advertising and the core findings about left- and right-brain elements in advertising
• How the left brain has become more dominant over time
• How right-brain elements are more effective but getting rarer
• Examples of ads with strong elements of each kind
• Implications for the ad industry
• What should marketers do differently? The manifesto for change.
