OG 63

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 manages used intuition significantly more that did most middle-or lower-level managers. This confirms the alternative view that intuition is actually more effective that careful, methodical reasoning.

A.      Methodical, step-by-step reasoning is inappropriate for making many real-life management decisions.

B.      Top managers have ability to use either intuitive reasoning or methodical, step-by-step reasoning 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-or lower-level managers

E是答案没问题. 但请大家讨论下B, D. 我觉得OG的解释不明.

B:OG说leave open the possibility. 什么意思? 指该条件默认?如果这个条件不满足, 例如Top managers只能用intuitive, 而Middle-or lower-level只能用methodical, 那么比较这两种方法将毫无意义..

D: 是最麻烦的. 举个量化的例子:

                                     intuitive          methodical            total

Top managers                4                   6                           10

Middle-or lower-level    1                   9                            10

Top managers共做10个决定, 有4个用intuitive reasoning;  Middle-or lower-level managers 也做10个决定, 有1个用intuitive reasoning. 4:1, 满足significantly more的题目条件. 但如果Top managers用methodical, step-by-step reasoning做了剩下的6个决定, 能得出结论:  Intuition is actually more effective that careful, methodical reasoning?

除非: 剩下的决定不是用 methodical法做的. 但题目的意思显然将两种办法对立起来了.

欢迎大家讨论.

(今天我一天就折腾这两道题...什么时候才能上岸?...)

You definitely went far in this question. I try to explain:

using your example, if the top managers use intuition 40% of the time and get 40% of their decisions right, and middle- and lower-level managers use intuition 10% of the time and get 10% correct decisions, the argument is well supported while D is violated.

Thank you, mindfree NN

Now I learnt  that to being effective, we need a higher ratio of success, not highter number that this method was used, no matter who uses it.

BTW, OG explains B option like this: "Since the argument leaves open the possibility of situations in which top managers are unbale to use one of the methods, choice B is inappropriate."   I guess that "leaves open the possibility" means this possibility is not involved, so it's irrelative, isn't it?

thanks again.

I really appreciate it.

hi, guys, thanks

I felt depressing. All the arguments are separateing parts in my eyes. I cannot find their internal relations. For almost every sentence as well as every option, I have to spend much time to understand their logic meanings. But now I feel encouraging. Maybe what I need are more practices.

HOHO~~ dear liu, you just think too much about each choice and its potential relationship to the key points. But from my undersanding, ETS never let this potential relationship work. At the beginning, I made the same mistakes with you from time to time. So..just relax..and cheer up!!

Although my logic is NOT as good as many NNs', I still insist my own opinion and wanna share it with you. I only pay attention to the most correct answer and the second one when reviewing CR. Since ETS only think over these two choices. The left three choices are meaningless both for ETS and for me. Save your time and do sth. else more meaningful..such as...chatting with me...hahahahahahahahaha~~~~~~~~~~~

oh, dear scots MM,

I cannot agree with you. Many NNs said they can tell you every option of OG 205 why it is wrong or right. Maybe it doesn't fit to you. But for me, I have to use this step-by-stey method.

Anyway, thank. remember: see you in US!
