Psychological rule(2)

"The rule of Shochikubai" is one of the visual methods mainly used for purchasing products. The rule is that when humans are presented with three products with different values, many people think that the middle option is safe and choose it. If you remember this rule in the scene of choosing one from three products, you will be able to make a decision without being influenced by the seller's wishes.

"The rule of avoiding decisions" states that when humans are presented with too many choices, they often refuse to narrow it down to one. Sheena Iyengar, a university professor, conducted an experiment to determine the purchase rate of 6 jam and 24 different kinds of jam in a store. The results showed that the purchase rate of the 6 kinds of jam was much higher than that of the 24 kinds of jam. This means that if people have too many choices when buying something, they are likely to have trouble. Based on the results of this experiment, writers should limit the number of choices on the site as much as possible, and if there are too many, you should split the question into several parts. This method, which allows people to continue answering without feeling uncomfortable, is often used in XX diagnosis and surveys.
