Masalah dalam Pengambilan Keputusan

• Pengetahuan pengambil keputusan yang belum memadai• Tidak lengkapnya informasi relevan

yang tersedia• Terbatasnya rasionalitas pengambil

keputusan (bounded rationality)

Apakah Kita Rasional?

• Bounded rationality: suatu kondisi bahwa dalam pengambilan keputusan, individu mempunyai keterbatasan informasi, kemampuan kognitif, dan waktu.

• Cognitive Bias: pola penyimpangan dalam pengambilan keputusan pada situasi tertentu karena distorsi persepsi, ketidakakuratan prediksi, interpretasi yang tidak logis, atau tidak rasional.

Heuristics: individu menggunakan strategi (taktik) sederhana atau rules of thumb dalam pembuatan keputusan (Tversky

Teori Psikologi pada Bias kognitif• Referent point effect• Prospect theory (framing effect)• The conjunction fallacy: the tendency to

assume that specific conditions are more probable than general ones.

• Hindsight vs Foresight Bias• Data Fixation• Order effect: primary vs. recency effect• Anchoring and adjustment• Self-Fulfilling Prophecy

Referent Point• A newly hired engineer for a computer firm in

the Boston metropolitan area has four years of experience and good all-around qualifications. When asked to estimate the starting salary for this employee, my scretary (knowing very little about the profession or the industry) guessed an annual salary of $23,000. What is your estimate:

$ _____________ per year

The importance of framing• Imagine that you have just learned that the sole supplier of a

crucial component is going to raise prices. The price increase is expected to cost the company $6,000,000. Two alternative plans have been formulated to counter the effect of the price increase. The anticipated consequences of these plans are as follows: (Check the one you would adopt)– If plan A is adopted, the company will save $2,000,000.

– If plan B is adopted, there is a 1/3 probability that $6,000,000 will be saved and 2/3 probability that nothing will be saved.

-------------------------------------------------------------------------------------------

o If plan A is adopted, the company will lose $4,000,000.

o If plan B is adopted, there is a 1/3 probability that there will be no loss, and a 2/3 probability that the company will lose $6,000,000.

Appreciating sample size• A certain town is served by two hospitals. In the larger hospital

about 45 babies are born each day. In the smaller hospital about 15 babies are born each day. Overall, about 50% of all babies born are boys. However, the exact percentage varies from day to day. Sometimes it may be higher than 50%, sometimes lower. For a period of one year, each hospital recorded the days on which more than 60% of the babies born were boys. Which hospital do you think recorded more such days?– The larger hospital.

– The smaller hospital.

– About the same

Appreciating sample size (2)

• An investor is looking to invest some money in the stock market. Each week for six straight weeks the investor receives a prediction about a particular index fund's performance from a stock broker. Each week the stock broker correctly predicts whether the fund will go up or down over the ensuing week. What do you think the probability is that the investor would be willing to pay for the broker's seventh prediction?
