⑴人們對難分高下的選項進行比較時，因爲一個新的選項，也就是一個誘餌的加入，使某個選項更具吸引力。
⑵每個人心裏都有一杆秤，用于測算各種商品的效用價值。但當選項中多個因素（價格、性能、數量）各有優劣的時候，我們看不出門道。但是，我們可以輕易察覺出某種商品和其他商品之間的比較關係。就是你單拿一個出來，我不知道你好還是不好，但是我很容易知道你和另一個比，哪個好，哪個不好。所以，紅花是否吸引人，很多時候是源于綠葉的“陪襯”。
⑶當人們在選擇旅遊目的地時，遇到兩個看起來很吸引人的選項，但很難決定。突然，一個旅行套餐被引入，這個套餐在價格上稍微高一點，但提供了額外的旅遊活動和福利。這個新的選項成為誘餌，使得其中一個原本吸引人的選項更加顯眼。
在一個電子產品店裡，顧客正在考慮購買一台新的電視。有兩款電視在價格和功能上差不多，讓顧客難以做出決定。店主巧妙地在其中一款電視旁邊放置了一個誘餌，這個誘餌是另一個價格較高的電視，但擁有更高的解析度和更多的連接選項。這個誘餌使得原本的選項看起來更有價值，讓顧客傾向於購買它。
一家餐廳推出了午餐套餐，包括主菜、配菜和飲料，價格相對較高。此外，他們還提供了一份單點午餐菜單，價格較低，但只包括主菜，需要額外付費才能添加配菜和飲料。這個午餐套餐成為誘餌，使得原本的單點午餐菜單看起來不那麼吸引人，因為顧客可以以相對較少的錢獲得更完整的用餐體驗。
⑷運用誘餌效應：
① 次、優選項襯托。
② 設置一個中間價格，提升人的購買欲。
③ 套餐打包售賣。
Decoy Effect
1.When people compare options that are difficult to distinguish between, the addition of a new option, also known as a decoy, makes one option more attractive.
2. Everyone has a mental scale for assessing the utility value of different products. However, when multiple factors (price, performance, quantity) have their own advantages and disadvantages, it becomes challenging to determine the best choice. However, we can easily perceive the comparative relationship between a certain product and other products. Whether a red flower is attractive often depends on the "accompaniment" of the green leaves.
3.1 When choosing a travel destination, people may encounter two options that seem equally appealing, making it difficult to decide. Suddenly, a travel package is introduced. This package is slightly more expensive but offers additional activities and benefits. This new option becomes a decoy, making one of the initially attractive options more prominent.
3.2 In an electronics store, a customer is considering buying a new television. There are two televisions that are similar in price and features, making it difficult for the customer to decide. The store owner strategically places a decoy next to one of the televisions. This decoy is another television with a higher price but higher resolution and more connectivity options. This decoy makes the original options appear more valuable, influencing the customer's inclination to purchase it.
3.3 A restaurant introduces a lunch set that includes a main dish, side dishes, and a beverage, at a relatively higher price. Additionally, they offer an à la carte lunch menu at a lower price, but it only includes the main dish, with additional charges for adding side dishes and a beverage. This lunch set becomes a decoy, making the original à la carte menu less attractive because customers can have a more complete dining experience for a relatively lower cost.
Applying the Decoy Effect:
Highlighting a secondary or superior option.
Setting a middle price point to enhance purchasing desire.
Bundling items into packages for sale.
