The WYSIATI effect (What You See Is All There Is) refers to the fact that people often only consider the information that is available to them when making decisions, instead of looking for or considering other relevant information. In other words: What you see is all there is.

In neuromarketing, the WYSIATI effect is used to influence consumer decision-making. For example, if a website only presents limited information about a product or service, the consumer may tend to make a decision based on this limited information without conducting further research.

One example of the application of the WYSIATI effect in neuromarketing is the use of social proof, such as customer reviews or recommendations. If consumers only receive limited information about a product on a website, positive reviews from other customers can help them to decide in favour of the product, as they consider the opinion of others to be sufficient.

Another example of the WYSIATI effect in neuromarketing is the use of default options. If a consumer only receives limited information on a website, the use of default options can help them to decide in favour of this option without looking further at the other options.
