할인쿠폰을 오프 매장에서도 사용할 수 있냐는 질문에 대한 영풍과 교보문고 답변의 차이점 생각해 보기:

<영풍>
안녕하세요. 영풍문고 입니다.
할인쿠폰은 인터넷 주문시에만 사용가능합니다.
감사합니다.
</영풍>

<교보>
안녕하세요. 김창준님,
교보문고 오선미입니다.

고객님의 문의내용에 대하여 답변드립니다.
인터넷 구입시 구매금액에 따라 증정되는 할인쿠폰은 온라인 구매시에만 이용가능한 인터넷 할인쿠폰이므로, 오프라인 매장에서는 이용이 불가하오니 이 점 양해 부탁드립니다.

기타 문의사항이 있으시면 언제든지 고객센터(1544-1900)나 1:1 Q&A를 통해 문의주시길 바랍니다.
</교보>

"Importance of macrocognition"

http://www.freakonomics.com/2007/08/09/freakonomics-quorum-the-economics-of-street-charity/

Read the question, think yourself and jump to Taleb's answer. Then compare it with others' answers. This article is particularly meaningful to testers and decision makers.

The difference of results between laboratory experiments and natural setting events has been pointed out often by cognitive psychologists. Some call them microcognition vs. macrocognition. http://en.wikipedia.org/wiki/Macrocognition

BTW, I believe there are a couple of mistakes in Taleb's answer. He wrote:

> While the people in the experiment preferred B over A when seen sequentially,
> they preferred A over B when seen jointly.

, which should have been instead:

While the people in the experiment preferred A(better appearance) over B(better sound) when seen sequentially, they preferred B(better sound) over A(better appearance) when seen jointly.

And I believe his reference to the research was mistaken, as far as I know. Hsee didn't do the empirical research on stereos with appearance and sound quality attributes as variables.

Instead, he has done research comparing audios with different sound quality and different power(in watt), which was done in a different context(lay scientism) -- it was not about comparing joint/sequential evaluations. Hsee, C. K., Zhang, J., Yu, F. and Xi, Y. (2003), Lay rationalism and inconsistency between predicted experience and decision. Journal of Behavioral Decision Making, 16: 257–272. doi: 10.1002/bdm.445

Actually, he refers to a fictitious anecdote of buying a pair of speakers(instead of stereos) in Hsee, Christopher K., Attribute Evaluability and Its Implications for Joint-Separate Evaluation Reversals and Beyond. CHOICES, VALUES AND FRAMES, D. Kahneman & A. Tversky, eds., Cambridge University Press, 2000. Available at SSRN: http://ssrn.com/abstract=936581

However, this phenomena, called distiction bias, is well known and based on many empirical researches in different settings.

안녕하세요.

제4회 한국 SW 아키텍트 대회 기조연설을 위해 방한한 Joseph Yoder라는 분이 xper 모임을 위해 번개에 오시기로 했습니다.

애자일, 리팩토링, 테스팅, 아키텍춰, 패턴 등에 대해 전문가이신 분이고 특히 Big Ball of Mud(http://www.laputan.org/mud/ )라는 패턴 언어의 공동저자로 유명합니다.

http://onoffmix.com/event/3297

여기에서 신청하실 수 있습니다. 이번에는 좀 적은 숫자로 편안한 자리를 만들어보려고 선착순 20명을 잡았습니다. 시간 되시는 분들 오셔서 유익한 시간 가지시길 바랍니다.

이번에는 참가신청시에 연사에게 묻고 싶은 질문에 필수로 답하셔야 합니다. 당일날 토론시에 활용하도록 하겠습니다.
