Traditional economics assumes that people make decisions rationally and after careful consideration. In practice, however, Homo sapiens rarely resembles Homo economicus. We are not machines that coldly calculate profits and losses. We are beings who, despite millions of years of evolution, make decisions under the influence of emotions and unconscious impulses. Behavioural economists and experts in neuromarketing are aware of this and use it to sell us products and services.
Daniel Kahneman, who was awarded the Nobel Prize in Economics in 2002, demonstrated together with Amos Tversky that people make decisions based on emotions and heuristics (mental shortcuts). These simplified rules of thought enable quick decisions, but ones that are usually inaccurate.
The first of these cognitive mechanisms is the anchor effect. This means that the first piece of information we are given – such as the price – becomes our benchmark. For example, if a shop reduces the price from 500 to 300, customers see this offer as a great opportunity, regardless of the product’s actual value.
The second cognitive mechanism is the availability heuristic (mere-exposure effect): we consider things to be more important or more likely if an example immediately springs to mind. Insurance companies exploit this by showing specific claims in their adverts, leading us to buy policies we may not even need.
The third is the certainty effect: people prefer a small but guaranteed profit to the chance of a large profit. A “free gift with every order” is often more appealing than competition.
The fourth is loss aversion: adverts such as “Offer ends in 2 hours” or “Only 24 left in stock” attract customers like a magnet. Loss aversion is also linked to the FOMO effect (fear of missing out). This causes market participants to make irrational decisions under the influence of social pressure and the fear of missing out on an opportunity (see, for example, recent buyers of precious metals on the stock market).
The fifth is cognitive ease: used in marketing through consistent branding and slogans. If a message is repeated often enough, it ‘slips’ into the brain without resistance. This builds trust, even when there are no factual arguments to back it up. This is combined with clear presentation (visual ease) and ease of content (simple language, humour).
The sixth is the effect of scarcity. When a well-known brand announces a limited-edition product, people often react with enthusiasm. They see it as something exclusive and rare that will enhance their status and self-esteem. Nobody asks whether the product is worth the price.
The seventh is framing – the construction of an appropriate narrative.
The eighth is the halo effect. We are more likely to believe attractive, well-dressed people than those who look average, unattractive or poor, even if this says nothing about their competence.
Modern neuromarketing has long since incorporated all these effects and is taking things further by utilising the latest discoveries in neurobiology, cognitive science, psychology, data science and artificial intelligence. It examines not only human behaviour, but also its biological basis.
Politicians make massive use of neuromarketing, and we fall for it. They simply talk (Trump’s cognitive ease). They show us gruesome images of destroyed Ukrainian cities and say: ‘The war may soon come to you if you don’t pay more tax for defence spending. You must buy and produce weapons immediately, otherwise it will be too late’ (FOMO).
Politicians want to keep pay rises in the public sector as low as possible, so they stir up the trade unions, who then demand a far-fetched 15% increase (the anchor). Both sides then agree on 5%, and the electorate (the customers) are happy (the certainty effect).
Politicians never talk about necessary tax increases, but rather about ‘investing in the future.’ Instead of talking about ‘restrictions on freedoms,’ they talk about ‘security measures.’ Statistics: Voters are more likely to support a programme that promises ‘95% employment’ than one that talks about ‘5% unemployment,’ even though mathematically it is the same thing. Both are examples of framing.
Olaf Scholz positioned himself as Angela Merkel’s successor (even copying her diamond-shaped hand gesture). He capitalised on the fact that voters’ brains favour what is familiar (the mere-exposure effect). For Germans, voting for Scholz was ‘cognitively easy’ – not a revolution, but stability that provided a sense of security.
Youthfulness, impeccable looks and energy created a strong halo effect for Macron and Trudeau. Voters unconsciously attributed economic and political competence to them (which, as newcomers, they could not prove) because they reacted positively to their overall presence and self-assured demeanour.
Brussels constantly relies on certainty and availability heuristics. Half-truths – such as the claim that the EU is beneficial for all member states – or outright lies – such as the assertion that we need ‘doctors’ from Somalia or ‘engineers’ from Rwanda – are repeated so often that, for some Europeans, these lies begin to feel like facts. It is claimed that leaving the EU is not worth it, as EU funding is so beneficial. Hardly anyone mentions that leaving could eradicate the demographically and economically devastating (green; LGBTQ) ideology. Hardly anyone mentions that leaving could enable Eastern and Central European countries to prevent the migration of their best skilled workers to Western Europe.
Just as in Brussels, the authorities in Beijing blow like the wind over the people, and the people (like grass) bend, as the sage Confucius once said. They operate a system of electronic surveillance involving thousands of cameras and facial recognition, and present it as concern for the citizen (framing). Citizens bend like grass under the pressure of the wind and are content that they are in the green in the state’s points system, allowing them to travel and enjoy small freedoms. The certainty effect.
One could go on listing examples for a long time. The main thing is that we understand the mechanisms and do not fall for them.
