雖然每個人都知道理性的思考是很重要的，但為何人們在做決策時還是受情緒影響？過去的研究中，經濟性原則的考量為過去研究再討論決策行為的重點，經濟人為期望最大化自身利益，並且有能力去評估各項選擇方案，他們認為管理者面對決策，都能以理性的、具有邏輯性的決策方式將問題清楚地來分析。但在日常生活中，我們所做的決策是否真的符合理性決策?有情感涉入的非理性決策是否才是現實上符合我們決策的縮影。
人們每天都在為了自己或者他人做大大小小的決策，也可以說：是決策構成我們的生活、也增進我們的生活，因此我們有必要知道自己在決策中是以何種因素考量而下決定。透過相關文獻的整理、訪談、歸納、分析、整合而認清問題，了解決策過程中理性或非理性因素的介入。本論文以婚姻為背景，進一步的討論出在決策步驟中，個體在資訊蒐集、制訂方案、選定方案與執行並審查方案時，理性與非理性因素介入與個人想法。在資訊蒐集時，個體會蒐集理性考量與非理性因素；且在選定方案時，是因為非理性因素(包含情感、情緒、感覺)來影響個人的決定；在執行方案時個體也有他們心中所浮現之想法。

Although everyone knows that rational thinking is so important, people still always make some decisions by irrational emotion. Previous studies of making decisions suggest that decision makers mainly maximize their own profit based on economical principle and also with the ability to assess every decision selection’s benefit and cost. They also indicate that most management level decision makers may use analytical, rational and logical ways to analyze every problem they encounter and when it refers to decision making. In our daily life, what do we exactly conform to the suggestion of rational decision making theories? Is irrational decision making with emotional involvement consistent with our daily choice and important decision?
People make all kinds of decisions no matter they are important or easy decision for himself /herself or for the others. In other word, decisions build up and make up our life, so it is important to understand what kind of factors affects our step of decision making. Through reviewing of the essays and theses, induction of the interview information, we realize rational and irrational factors intervene into the process of decision making. In terms to decision making, we choose “marriage” as our research scope, discuss rational and irrational factor affect decision makers’ thinking through the four step of decision making: information collection, development of programs, selection of program and implementation of program. In the step of information collection, individual will search for rational consideration and irrational element. Decision maker will make the decision and influence by irrational factors which include affection, emotion and feeling. When it comes to implementation, some ideas emerge in their mind.
