足夠滿意（
Satisficing
）
『這已經夠好了，我不想花更多時間學習如何用得更好。』
當人們看到 新的介面時 ，他們不會 有條理地細 讀介面上的 所有資訊， 然後才決定
「我認為這個按鈕最有機會完成我要做的事」。相反地，使用者很快地掃瞄介面，
直接挑選第一個看起來好像有可能的按鈕，然後就按下去了 — 即使這個按鈕可能
是錯的。
足夠滿意
（satisficing）是由
滿意
（satisfying）和
足夠
（sufficing）所組成的，是
社會科學家 Herbert Simon 於 1957 年所創造的詞，他用這個詞來描述各種經濟和
社會狀況下的人類行為。如果學習所有替代方案要花費時間與精力，人們願意接受
「夠好」，而不願意追求「最好」。
一旦你知道 「剖析」一 個複雜介面 所需要進行 的腦力工作 有多重，就 會瞭解「足
夠滿意」實際上是相當理性的行為。正如同 Steve Krug 在他的《Don
’
t Make Me
Think》（New Rider 出版）一書中所提到的，人們不想思考，除非有必要 — 只要
行得通就好了！但是如果介面呈現一兩個能讓使用者馬上看到的明顯選項，他就會
試試看。這有機會是正確的選項，就算不是，成本也很低，只要回頭嘗試其他的東
西就好了。（假設介面有支援「安全探索」。）
對設計師來說，這意味著幾件事：
•
在介面上使用「行動呼籲」的形式。提供首先可執行事項的指示，像是：在
此輸入文字、拖曳一張相片到這裡、點擊此處以開始……等等。
•
