Neuromarketing is a word that exists only in the business world, but it is not a term in the theory world. NEUROMARKETING OR CONSUMER NEUROSCIENCE It involves a much broader term, what is related to it: Consumer neuroscience. Marketing is the term in business like consumer neuroscience is in theory. It is also referred to as neuromarketing, but an interesting distinction between the two terms has been made by Hubert and Kenning (2008) who proposed that consumer neuroscience refers to the academic literature, whereas neuromarketing is the term used in the industry.
Human brains have 86 billion neurons (8.6 x 1010); neuroscientists investigate how these connect with each other and with other parts of the nervous system and the rest of the body. SO, IT IS=> Correlation between behaviour and things that can be observed in the brain of people when making decisions. Instead of us, firms would like to look at some strategies on what happens in our brain when we buy or not buy a thing, but why. (Ex. We are tired. Why? Ex. A specific product will be at the end of the supermarket because we are more prone to buy it) NEUROSCIENCES FIELDS Behavioural neuroscience: This is the study of how the brain affects behaviour. Cognitive neuroscience: This looks at how the brain forms and controls, thoughts and the neural factors that underlie those processes. During research, scientists measure brain activity while people carry out tasks. This field combines neuroscience with the cognitive sciences of psychology and psychiatry. Cultural neuroscience: This field looks at the interaction between cultural factors and genomic, neural, and psychological processes. It is a new discipline that may help explain variations in health measures between different populations. Findings may also help scientists to avoid cultural bias when designing experiments. Social neuroscience: this is an interdisciplinary field dedicated to understanding how biological systems implement social processes and behaviour. Social neuroscience gathers biological concepts and methods to inform and refine theories of social behaviour. It uses social and behavioural concepts and data to refine neural organization and function theories. How social nature of people can affect in social activity? BEHAVIOURAL ECONOMICS In order to understand neuromarketing, which is an application of neuroscience, we need to go back understanding the theory of irrational behaviour of economic decisions, how it has evolved through today’s application of consumer neuroscience. It all started with behavioural economics indeed. (Economics in the sense of theory of decision. People behave rationally we can study it making a formula, mathematical one to predict behaviour):
We have a common set of cognitive skills that are reflected in similar decision habits. But we also bring with us a common set of limitations on our thinking skills that can make our choices far from optimal (Hastie and Dawes 2001, 2). A central focus of behavioural decision researchers, then, is to identify the common set of cognitive skills, their benefits and limitations, and to explore how they help produce observable behaviour. They are not rational but act in a very predictable way. If everyone was different there could be not theory, but if on average they act the same way is ok. People want to be accepted, so being part of the group is of essence. RATIONAL OR IRRATIONAL is a very relative term, if we want to be part of our group also something irrational may become rational. Basically, behavioural decision making is the field that studies how people make decisions. Because all types of people are making all sorts of decisions all the time, the field is potentially very broad. What has characterized the field both historically and theoretically is the comparison of actual decision making with certain principles of rationality in decision making (Dawes 1998, 497). THEORY OF RATIONAL DECISION MAKING (a) Do people perform the way that the models claim they should? How should people decide? (b) If not, how can people be helped to improve their performance? PREDICTABLE IRRATIONALITY People are not rational, not all the time, they make irrational decision which are very similar among them. Fortunately, after a lot of research and hypothesis testing, trends and concepts have emerged. And one really great thing has been discovered: While people are not logical or rational, they are very PREDICTABLE (Dan Ariely's book, Predictably Irrational, consistently shows this). Our brains evolved over a long time and have generally formed the same rules of thumb, scanning mechanisms, and other behaviours In order to understand how people behave in irrationally predictable ways, we can explore how brain works (briefly) HEURISTICS AND BIASES
How they apply to economics? Heuristics are based on practical intuitions. The heuristics and biases terms were identified by Tversky and Kahneman 1974 Science paper ‘Judgment under Uncertainty: Heuristics and biases’ and a 1982 volume with the same title (Kahneman, Slovic and Tversky 1982) We will study what heuristics and biases are (some) and see how they apply to economics and ultimately can help understanding marketing strategies People decide according to very few practical heuristic principles, instead of using the mathematical theory of 19th^ century, people use heuristic principles. ‘Judgment under Uncertainty: Heuristics and biases’ (Tversky and Kahneman 1974) “This article shows that people rely on a limited number of heuristic principles which reduce the complex tasks of assessing probabilities and predicting values to simpler judgmental operations” (Tversky and Kahneman 1974, 1124) “In general, these heuristics are quite useful, but sometimes they lead to severe and systematic error” (Tversky and Kahneman 1974, 1124). TO SUM UP We move from TRADITIONAL ECONOMICS to BEHAVIORAL ECONOMICS - > Observation of irrationality: HEURISTICS AND BIASES! Can we measure more directly the presence of biases without asking people directly (and perhaps avoid some of the biases)? Neuromarketing: physiological measures of brain activities (various ways) related to biases and irrational behaviours - > SOME EXAMPLES Can we fix biases? Or use them in a positive way? NUDGES=> A WAY TO MAKE PEOPLE MAKE THE RATIONAL DEICSION WITHOUT FORCING THEM. EX. Participation to organ donation, seeing the percentage of people deciding to donate organs. Spain was high, Italy medium, reasons may be cultural and so on. They found out that there is a problem in some countries you must decide to be part of the group which donates, in some others you are automatically in the group, but you can decide to opt out.
Definition: Motivated biases stem from personal desires, emotions, or self-interest, leading individuals to interpret or seek information in a way that aligns with their goals or beliefs. Why It Happens: These biases are emotionally driven and help protect self-esteem, maintain social identity, or support preferred outcomes. NEUTRAL BIASES Definition: Neutral biases occur when errors in judgment happen without clear cognitive or emotional influence, often due to external factors like framing effects or defaults rather than internal motivation or reasoning errors. Why It Happens: These biases are context-dependent and often shaped by how information is presented rather than deep-seated cognitive or emotional influences. HEURISTICS Heuristics are a way in which a way responds to some requirements of the brain in terms of decisions, a way to decide fast, immediate and intuitive. Can be efficient way to make decision but in modern life it can lead to biases. In behavioral economics, a heuristic is a mental shortcut or rule of thumb that people use to make decisions quickly and efficiently. Heuristics help simplify complex problems by reducing cognitive effort, but they can also lead to systematic biases and errors in judgment. Unlike traditional economic models, which assume individuals make decisions rationally and optimally, behavioral economics recognizes that people rely on heuristics under conditions of uncertainty, limited information, or time constraints. While heuristics often produce good-enough decisions, they can sometimes result in predictable cognitive biases.
They save time and effort – Allowing for quick, intuitive decision-making. They work well in many cases – Often leading to reasonable choices. But they also introduce biases – Causing predictable errors that impact economic and consumer behavior. ACTION BIAS The action bias describes our tendency to favor action over inaction, often to our benefit. However, there are times when we feel compelled to act, even if there’s no evidence that it will lead to a better outcome than doing nothing would. Our tendency to respond with action as a default, automatic reaction, even without solid rationale to support it IN EVERYDAY LIFE: A SCHEMATIC BREAKDOWN The Internet Lag Dilemma Problem: Slow-loading website or app. Instinctive Action: Repeatedly refresh the page or close and reopen the app. Reality: This doesn’t speed up the process—sometimes waiting is the only solution. The Water-Damaged Laptop Scenario Problem: Spilling water on a powered-off laptop. Instinctive Action: Frantically press the power button to check if it still works. Reality: Turning it on increases damage by pushing water deeper into the circuitry. Best Solution: Let it fully dry (e.g., in a bag of rice or in front of a fan). The Key Takeaway More action ≠ better results—sometimes inaction is the smartest move! WHY IT HAPPENS?
Modern life rewards action—whether it’s answering emails instantly or reacting to social media notifications. We are conditioned to believe that inaction = laziness or inefficiency. Example: In meetings, leaders make unnecessary decisions just to show they are in control, instead of waiting for more data. Action bias is a mix of instinct, emotion, and social pressure that drives us to act—even when the best choice is to wait. Recognizing this bias helps us make more strategic, thoughtful decisions instead of reacting impulsively. ACTION BIAS IN TRADITIONAL MARKETING
Reduces friction in the purchasing process. Instead of thinking, customers instantly act with one click. Marketing Tip: Reduce decision barriers with simplified checkouts.
In the 1 st^ experiment:
The anchoring bias is a cognitive bias that causes us to rely heavily on the first piece of information we are given about a topic. Humans tend to remember and focus more on the prominent features displayed in the first part of any information displayed. When we are setting plans or making estimates about something, we interpret newer information from the reference point of our anchor instead of seeing it objectively. This can skew our judgment and prevent us from updating our plans or predictions as much as we should. It presents itself in such a way that it compels the human mind to arrive at an early hypothesis, even failing to adjust to the latter information. EXAMPLES For example, if you are out shopping for a shirt; you look through the entire store only to end up buying the first one you had picked out. Another example is, if you've set out to buy a watch for $50 and you see a watch that you like for $150, you decide not to buy it. But, if you see another watch that you like that is priced at $75, you think it’s relatively cheaper than $150 - even though it’s more than your actual budget. In this example, the watch that you see for $150 is your anchoring reference point. This is a clear example of how the Anchoring Bias affects our everyday life. WHY IT HAPPENS? The original explanation for the anchoring bias comes from Amos Tversky and Daniel Kahneman: in a 1974 paper called “Judgment under Uncertainty: Heuristics and Biases,” Tversky and Kahneman theorized that when people try to make estimates or predictions, they begin with some initial value, or starting point, and then adjust from there. The anchoring bias happens because the adjustments aren’t usually significant, leading to faulty decision-making. This has become known as the anchor-and-adjust hypothesis
Anchoring can have both positive and negative effects depending on the price that the individual is exposed to first. If a customer first sees a product at its original, non-discounted price, this number will become an anchor. If they subsequently see a discount offer, they will evaluate this as a great deal! Similarly, if the customer is first exposed to the product at a reduced rate, returning later to the standard price may be viewed as unreasonably high. In crafting messaging, marketers can leverage Anchoring Bias for more effective messages. The easiest way to do this is to focus on the numbers. When the target audience is uncertain about a number, they will take a guess based on the most recent number they were primed with. MARKETING EXAMPLES
Example: Spotify, Netflix, Adobe Subscription services often present three-tier pricing: Basic Plan: $5.99/month (Limited features) Standard Plan: $11.99/month (Popular choice) Premium Plan: $18.99/month (Extra features but costly) The highest price serves as an anchor, making the mid-tier plan appear like the best value. Tip for Marketers: Use strategic pricing tiers where the middle option feels like the "smart choice."
The Ellsberg paradox ... Which bag dID you choose? AMBIGUITY EFFECT-AMBIGUITY AVERSION Ambiguity aversion refers to the tendency of individuals to prefer known risks over unknown risks, even when the expected outcomes are the same. This cognitive bias leads people to avoid choices where probabilities are uncertain, favoring options with clear, well-defined probabilities Ellsberg Paradox: Demonstrates how people irrationally favor options with known probabilities over ambiguous ones, even when it leads to inconsistent decision-making. Psychological Mechanisms: Fear of the unknown—uncertainty triggers discomfort. Lack of control—clear probabilities provide a sense of predictability. Worst-case thinking—people assume ambiguity means a higher chance of negative outcomes. WHY IT HAPPENS? It has been suggested that the ambiguity effect is the result of a heuristic used to facilitate decision-making. This strategy occurs automatically and effortlessly, helping you to reach a conclusion quickly. To an extent, the ambiguity effect is an adaptive response. People prefer options that they feel well-informed about to options that they feel leave too much to the imagination. This can be useful for avoiding options for which we genuinely have too little information to go on. Even better, the ambiguity effect can lead us to seek out more information about the ambiguous option, so as to make a more informed decision. IMPLICATIONS IN MARKETING Ambiguity aversion plays a significant role in consumer behavior, influencing purchasing decisions, brand preferences, and risk perception. Marketers can use this bias strategically to reduce uncertainty and make products more appealing to hesitant customers.
Solution: Provide clear, specific details (e.g., "Clinically proven to reduce wrinkles by 30% in 4 weeks" instead of "May improve skin appearance"). Example: Apple provides detailed specs and performance benchmarks for its devices to eliminate doubts.
