人們會藉由查詢外部資訊滿足自身對事物之不確定性，然而當事物同時具有正面與負面表述之不一致性時，此矛盾情形如何影響人們的感知，學者卻抱持不同觀點。有些學者認為人們會因此感到困惑，有些學者卻認為人們會因此更謹慎地做選擇。即便如此，此現象反應資訊不一致性會影響資訊接收者的感知，同時亦反應單就資訊不一致性難以確切地衡量資訊接收者的感知。有鑑於此，本研究將資訊循序性 (正面、負面或負面、正面表述資訊的排序) 與資訊時間間距 (兩資訊間的時間差距) 等因素納入考量，探究人們面對不一致之循序性資訊時，是否會因兩資訊間的時間間距長短，影響人們對資訊的信任，並以電子商務之顧客二次評論機制作為實驗情境。;Previous studies have shown that people could search for external information to reduce their uncertainty, however, if the information brings positive and negative expressions simultaneously, the information inconsistency would happen. There are disagreements among researchers about how this contradictory situation affects the perception of people. Some researchers showed that people would become confused, and others considered that people would make choices more cautious. Nevertheless, this shows that information inconsistency would affect the perception of the information receiver, and it is still not enough for measuring the perception of people by the factor of information inconsistency individually. Accordingly, this study would take the factors of sequentiality (the sequential of contradictory expressions) and time interval (time interval between information with contradictory expressions) for consideration, aiming to explore the interaction effect of sequential information inconsistency and time interval on trustworthiness. The mechanism of two-stage reviews in e-commerce would be our experimental situation in this study.
