Traditionally, decision making by managers that is reasoned step-by-step has been considered preferable to intuitive decision making. However, a recent study found that top managers used intuition significantly more than did most middle- or lower-level managers. This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning.

The conalusion above is based on which of the following assumptions?

(A)Methodical, step-by-step reasoning is inappropriate for making many real-life management decisions.
(B)Top managers have the ability to use either intuitive reasoning or methodical, step-by-step reasoning in making decisions
(C)The decisions made by middle- and lower-level managers can be made as easily by using methodical reasoning as by using intuitive reasoning.
(D)Top managers use intuitive reasoning in making the majority of their decisions.
(E)Top managers are more effective at decision making than middle- and lower-level managers.

這題答案是(E)
可是我覺得(B)更是假設前提ㄟ
請問大家看法

所謂假設是: 沒有該假設，結論得不出

B只說TOP MANGERS二種DECISIONS MAKING METHODS都會用

這跟結論--->intuition is actually more effective than careful, methodical reasoning一點關係也沒有哩

要不要再想想？還是把你認為B正確的理由說出來？我們一起來看看

這是三段式推論
一、高階經理人愛用直覺
二、(假設)
三、直覺比較有效

所以就是有講直覺，也有講有效，就是假設了，這種做法類似大陸人常說的"搭橋"
搭起了一與三的橋，就是答案

[himorgan]

大概了解你的意思
當時我是認為跟middle- and lower-level managers比
變成跟其他人比
這個答案選項很怪(因為是本身愛用啊)
而且本身要有此種能力
此種結論才能成立啊
不過如果又文字連結推的話
也只能選這個答案了

試著將E "取非":

If top managers are NOT more effective at decision making than middle- and lower-level managers. 如此一來, 我們就無法合理推出結論說 直覺判斷比methodical reasoning有效....

[evelight]

嗯嗯....接著問 ^^;

那麼D呢？
OG說: The argument is consistent with managers at all levels using intuition in the minority of
decisions made. Thus, choice D is inappropriate.

是說D的邏輯跟using intuition in the minority of decision made都是『以"量"認定』所以錯誤嗎？

謝謝...

[Calvin]

OG 是把 D 取非後，說明「即使top managers use intuition in the minority （不是D的majority）也不會改變原文推論」

所以D不會是假設！

FYI

[evelight]

感謝~~~

原來『取非』是這樣用的.... ^^

[Calvin]

evelight如果想要更詳細知道取非的用法

可以參考我在另外一題的回答

這題有個關鍵字: alternative
所以答案跟那個 alternative 的結論是同一件事,不同的說法
top managers use intuition;
以閱讀來看: {intuition = more effective} 其實就是 {top managers = more effective}
以邏輯關係表示: {top managers = more effective} => {intuition = more effective}
