在做選擇決策時，消費者會發現許多困難與障礙，使得他們延遲去做選擇。現存關於決策的文獻研究，已經探討當消費者偏好不選擇的選項的起因和條件。本篇研究探討理想點可取得性在吸引力差異對延遲選擇的干擾效果。與先前的研究結果一致，當消費者沒有一個理想點時，在吸引力差異小 (vs.大) 的時候，會更傾向於延遲選擇。然而，當消費者有一個理想點時，在選擇集合中的吸引力差異對延遲選擇則沒有影響。透過兩個不同的實驗，我們檢驗理想點可取得性的干擾效果。

When making a decision, consumers find many difficulties and obstacles that make them defer choice. Extant research in decision-making literature has discussed the causes and conditions when consumers prefer the no-choice option. Building on constructive view of preference, this research is contributed by defining the ideal point availability of consumers, which most of the time is not specified. The current research examines the moderating effect of ideal point availability in attractiveness difference choice set on choice deferral. Consistent with prior research, when consumers don’t have an ideal point, the tendency to defer choice is higher in a small than large difference in attractiveness choice set. However, when consumers have an ideal point, the attractiveness difference in a choice set has no impact on choice deferral. With two different studies, I examine the moderating effect of ideal point availability.
