Alchemy: Why Illogical Ideas Often Beat Logical Ones in Marketing
A Kurums Book Taste review of Alchemy for marketers who need a defensible case for creative, psychological solutions in organizations that only fund what a spreadsheet can explain.
Why this book fits Kurums
Sutherland, vice chairman of Ogilvy UK, has spent a career watching expensive logical solutions lose to cheap psychological ones. Alchemy is his case that human behaviour runs on perception, signalling, and context far more than on the rational calculations that budgets assume - and that the companies willing to exploit this find value their competitors cannot see.
For the Kurums Marketing audience the book is ammunition. It gives you vocabulary and examples to argue for brand, design, and behavioural interventions in meetings dominated by finance and engineering, and it reframes marketing from a cost centre that persuades people into a discipline that changes how value is perceived.
What the book argues
The core argument is that logic is a poor guide to human behaviour because people optimize for things that are hard to measure: status, reassurance, effort, fairness, and the avoidance of looking foolish. Sutherland's favourite examples - the London-Paris train where free Wi-Fi and better service would beat billions spent on speed, or Red Bull succeeding precisely because it tastes odd and costs more - show that perceived value can be engineered more cheaply than objective value. The opposite of a good idea, he likes to say, can also be a good idea.
The second argument is about signalling and costly effort. Brands, packaging, guarantees, and even inefficiency communicate commitment in ways that efficient alternatives cannot: a firm that spends on advertising is visibly betting on its own future, and customers read that bet. Sutherland connects this to evolutionary psychology and behavioural economics - satisficing, loss aversion, the placebo effect - to explain why apparently wasteful spending often builds trust, and why cost-cutting that removes signals can destroy demand.
The third argument is organizational. Large companies prefer 'logical' decisions because they are easy to justify after the fact, not because they work better; no one is fired for following the spreadsheet. This bias starves the business of small, cheap, psychologically clever experiments, which Sutherland calls 'psycho-logic'. His prescription is to protect a space for testing counterintuitive ideas, to measure what customers feel as well as what they do, and to treat reframing - changing the context of a choice rather than the product - as a legitimate, high-return lever.
Key ideas, translated to your desk
Change perception before product
Before funding an expensive product fix, test whether reframing, packaging, or reducing anxiety solves the same customer problem for a fraction of the cost.
Protect the signals
Guarantees, design quality, and visible investment tell customers you are committed. Audit cost-cutting proposals for the signals they would silently remove.
Budget for illogical tests
Reserve a small, ring-fenced share of spend for ideas that cannot be justified in advance. Judge them on results, not on how rational they sounded.
Use it at work
- Run a quarterly 'psycho-logic' session: list your top customer frustrations and brainstorm perception fixes before product fixes.
- Review the next cost-reduction plan for removed signals - packaging, service touches, guarantees - and estimate their demand impact.
- Allocate a fixed experiment budget for counterintuitive marketing tests with clear success metrics.
- Add perception measures (reassurance, effort, trust) to customer research alongside conversion and price data.
Read it if
- You defend brand and creative budgets against spreadsheet-only decision making.
- You want behavioural science made practical through memorable business cases.
- You enjoyed Ogilvy on Advertising and want its modern, psychology-driven successor.
You can skip it if
- You need a step-by-step marketing plan - the book is a mindset, not a playbook.
- Anecdote-heavy, discursive writing frustrates you.
- You want rigorous experimental evidence for every claim; some examples are illustrative rather than proven.
